SAFRAN NetClock Public Safety Master Clock Instructions

Update files do not need to be deleted before performing the update process.)

1.4.2 Archiving and Deleting Log Files
If the disk usage is higher than 70% (approximately), Spectracom recommends that you delete the logs and update files that may have been previously applied before performing the system software upgrade.

Archiving Logs
As an option, the logs can be archived (backed up) before deletion, by bundling
them into a single file, and then transferring them to your PC, all from within the
NetClock 9400 Web UI.

To archive logs:
1. In the Web UI, navigate to MANAGEMENT > OTHER: Log Configuration.
2. Click on Save and Download All Logs. This will generate a single bundled file (*.log) of the logs. Select where to save this file on your PC.

Deleting Logs and Statistics
To delete log files and statistics files, in order to cleanup disk space:

1. In the Web UI, navigate to TOOLS > SYSTEM: Upgrade/Backup.
2. In the bottom-left corner of the screen, take note of the Percent value, indicating how much disk space is currently used.
3. Then click on Clear All Logs, and then Clear All Stats below.
4. After completion of the process, the Percent value should show a smaller number, indicating how much disk space was cleared.

1.4.3 Deleting Old Update Files
Update files used in previously executed software upgrades are stored in the home/ spectracom directory. You can delete them individually via the Web UI (they are no longer used by the System, after the update has been applied).

To delete each update file:

1.4.4 Disk Cleanup Patch
Under some circumstances, clearing logs and stats conventionally via the Web UI (as described above) will require a second step in order to achieve an optimum restoration of disk space.

To this end, Spectracom provides a Disk Cleanup Patch that can be downloaded with instructions from https://files.spectracom.com/publicdownloads/ updatecleaner- securesyncnetclock- 9400, and run from within the Web UI. This Patch will clean items that are not user accessible otherwise.

1.5 Downloading the Upgrade Software Bundle
The new version system software upgrade (as well as previous versions, if needed) can be downloaded from the Spectracom Corporate website, see: Spectracom Support page for NetClock

Download the file(s) onto your PC, and note the location. If you download more than one file, the files will be bundled in a compressed file that needs to be extracted after download. Then, only upload the file updatexxx.tar.gz to the unit to be upgraded (where xxx = software version).

1.6 Hardware-Specific Steps
With certain hardware configurations and options (see below), the corresponding procedures described below must be carried out when upgrading from Versions 5.0.2 or higher to Version 5.9.8.

These instructions apply only, if one or several of these options are installed:

Trimble RES-SMT-GG Receiver
10/100 PTP Option
Gigabit Ethernet Option
Please note that these option-related procedures must be carried out only once, i.e. if you have previously upgraded your system from Version 5.0.2 to e.g., 5.1.5, you can skip this section.

1.6.1 Trimble RES-SMT-GG Receiver and u-blox M8T Receiver
Units shipped between 2Q 2014 and 3Q 2016 typically have a RES-SMT-GG GNSS receiver installed, while units built thereafter are equipped with a u- blox M8T receiver.

With either receiver, it may be necessary to execute the installation procedure twice in order to install not only the NetClock 9400 system software update, but also a GNSS receiver firmware update:

a. If your unit has a RES-SMT-GG receiver, AND you are upgrading from a version less than 5.1.5 to a higher version.
When upgrading from version 5.0.2 to 5.1.5 or higher, see “Required
Repeat of Upgrade Process” on page 23.
When upgrading from version 5.1.2 to 5.1.5 or higher, see “Potential
Need to Repeat Upgrade Process” on page 30.
b. If your unit includes a u-blox M8T receiver, AND you are upgrading from version 5.5.0 or lower to 5.6.0 or higher. See “Potential Need to Repeat Upgrade Process” on page 30.

Note: In cases other than the ones described above, the firmware update will be skipped automatically.

1.6.1.1 Determining the GNSS Receiver
Next, you need to determine which type of GNSS receiver is installed in your NetClock 9400.

Note: If the default Web UI of your unit is blue/white (rather than dark grey), your unit has a Res-T receiver.
1. If your Web UI is dark grey (see illustration below), navigate to Interfaces -> GNSS 0. The first line item under the default Main tab will report the GNSS receiver Model that is installed in your NetClock 9400. The example shown in the illustration below shows a “RES-SMT GG” receiver.

2. Take note of the receiver type installed in your unit.

When there are software updates that need to be automatically applied to the 10/100 PTP Option during the upgrade process, the upgrade process will take an additional 5 to 7 minutes longer, for each 10/100 PTP Option Module that is installed.

1.6.2 Gigabit Ethernet Option

Note: This section is not applicable when previously upgrading from versions 5.1.2 and above and the Ethernet ports have already been enabled by a user.

Important Notices when upgrading from version 5.0.2

When updating from versions prior to 5.1.2 with this Option installed, Eth1, Eth2 and Eth3 will all be disabled (not accessible by the network) upon applying this software update. If you are connected to one of these three ports to perform the update process, the time server will not be accessible once the update has completed. Further below is information about two different methods to enable each of these three Interfaces as desired, after applying the software update.

Because the three interfaces are disabled once the software update has completed, the network settings will appear to have been lost during the update.

However, the settings do actually persist through the update process. All of the settings will be present again, once each interface is individually enabled.

If the software was previously updated to versions 5.1.2 or higher, the three Ethernet ports will be in the same state (enabled or disabled) as they were before applying this update.

System software version 5.1.2 added a new feature which allows unused Ethernet interfaces (Eth1, Eth2 and/or Eth3) of the Gigabit Option , if installed, to be disabled via software for security purposes. Note this change does not apply to the base Ethernet port, “Eth0”, which cannot be disabled.

After applying this software update from version 5.0.2, all three of these Ethernet interfaces will be disabled. If any or all three of these interfaces are currently being used, after applying the software update (or if it’s desired to start using any of these three interfaces at a later date) the desired Ethernet interface(s) needs to be enabled. Until the interfaces have been enabled by a user, they will be inaccessible to the network.

Each of the three Ethernet interfaces can be enabled as desired, via either the web browser (using the “base” Ethernet interface “Eth0”) or by issuing a specific command with a CLI connection (telnet or SSH).

Enabling each interface using a CLI connection
After creating a CLI connection (using either telnet or SSH) the command to enable each desired interface is as follows: portset x on (where x is the Ethernet interface number – 1, 2, or 3 – for the interface you wish to enable). An example of enabling Interface “Eth1” is shown below:

14 NetClock 9400 Software

Enabling each interface using a web browser connection

To enable each desired Interface using the web browser, login to the browser using Eth0 (this interface is not disabled during the update). Navigate to the Management -> Network page of the Web UI. This will open a page displaying all four Ethernet interfaces (Eth0 through Eth3). The Status of Eth1 through Eth3 will be displayed as “DISABLED”.

For each Interface you wish to enable, click on the corresponding Gear button (center of the three buttons in that row). In the next screen that opens, click on the checkbox at the top of the page (as shown below). Then press either the Apply or Submit button to enable the interface. The port will now have the previous configuration as before the update was applied and will be accessible to the network.

CHAPTER 2

Upgrade Procedure
After completion of all preparation steps, the actual upgrade will be performed.
Chapter 2 will guide you through this process.

Depending on which software version is currently installed in your NetClock 9400 unit, proceed either to:
“Upgrading from V. 5.0.2 to a Newer Version” on the next page, or to “Upgrading from V. ≥5.1.2 to a Newer Version” on page 24.

2.1 Upgrading from V. 5.0.2 to a Newer Version

Note: Depending on the software currently installed on your unit, upgrading to the latest version may be a multi-step process. See “Determining the Correct Upgrade Procedure” on page 8 for more information.

The software upgrade process is performed using a PC that is either on the same network as the NetClock 9400 appliance, or is connected directly to the NetClock 9400 via a network cable.

Note: In order to perform the software upgrade, the Web UI of the unit to be upgraded must be accessible from this particular PC.

Once you downloaded the upgrade file onto a network PC, you can then transfer the file onto your NetClock 9400 unit, using the unit’s Web UI.

Note: Alternatively, you can also upgrade via Command Line
Interface: In this case, the file must be transferred manually, using FTP/SFTP, to the NetClock 9400 directory home/spectracom.

During the time that the file is being uploaded into NetClock 9400, the unit will remain fully functional and accessible for other network PC’s.

Once the file transfer is complete, NetClock 9400 is performing the software upgrade (“Upgrade System”), during which the unit is configured: Normally, all current NetClock 9400 configurations are automatically saved and restored as part of the update process. During the “Upgrade System” process, the front panel LCDs will go blank, and the unit will not be operational until the upgrade process has completed.

1. Local Clock: After updating from the “Classic” interface only SW Version (5.0.2) to a more recent version, you will have to create a new local clock, and apply it to the ports as desired. It is therefore advisable to write down any current Local Clock settings you may be using, before installing the new software.
2. Verify that LDAP has not been ENABLED inadvertently, by navigating to Network > LDAP Setup: If you are not using LDAP, DISABLE all services (if correctly configured, the services can remain ENABLED during the upgrade process).

3. Download the NetClock 9400 upgrade file (updateXXX.tar.gz) from the Spectracom website—see also “Downloading the Upgrade Software Bundle” on page 12—to an accessible directory on your local Windows machine (such as C:/Temp).
4. Open the Web UI, and login. Then navigate to Tools > Upgrade/Backup.

5. Ensure the Software/License Upgrade tab is orange (Orange indicates the tab is selected). Either click in the blank text box located next to Upload File, or select Browse to be able to select the update file (see illustration below).

6. Use the Windows® Explorer to navigate to the location on your network PC where the update file (updateXXX.tar.gz) was stored earlier (such as C:/Temp), and select it. Once the path appears in the text field (see illustration below), click the Upload button.

7. The file upload process may take several minutes. Once the file has been uploaded, the message “The file updatexxx.tar.gz has been uploaded.” (where xxx is the new version being applied) will be displayed underneath the field Upload Update/License File:

8. Now refer to the bottom of this page, under the title Upgrade the System. Ensure the correct file name (updateXXX.tar.gz) is selected in the box next to Update File.

9. Check the box next to Update System to install the software update.

Other available checkboxes:
Note: To perform the software update from an earlier software version to the latest version, only the checkbox next to Update System should be selected.

Force Update: When checked, will force the software to install all packages, even if it is already at the current revision, or (for example, it is desired to install version 5.9.8, even though version 5.9.8 is already installed). The software will reinstall over the previously installed packages.

USE CASE: This checkbox must be selected if it is ever desired to downgrade to a previous software version.
Delete Update File: When checked, will remove the Archive file that was uploaded into the unit. Note that this will not remove the file from your PC, just from NetClock 9400.

Note: If it is desired to remove the update file from the unit after completion of the upgrade process, note that the “Delete the Update File” checkbox should not be selected at the same time as the “Update System” checkbox. This process should be performed any time after the System Update process has been completed.

Restore Factory Configuration: When checked, will return NetClock 9400 to its original factory configuration.

USE CASE: This checkbox should be selected if it is ever desired to downgrade to a previous version (such as back to version 5.0.2, for instance).

During the System Upgrade you will see an analysis screen (as shown in the illustration below).

Note: If the unit has had any previous software updates applied and if any of the earlier upgrade files have not since been deleted from the unit, a Web UI screen may momentarily indicate the Upgrade process is “Complete”. This does not affect the software update process and the analysis screen will be displayed shortly thereafter.

**** Note: “OC” being displayed in the bottom rows refers to OPTION CARDS which may or may not be installed in your unit.

  Caution: Do not close the Web UI, or attempt to reboot the unit. The installation is in progress and may take several minutes to complete.

NetClock 9400 will reboot itself during the update process, as shown in the following screenshot:

Note: If using a DHCP assigned IP address (instead of having a statically assigned IP address), the unit’s IP address may change once the update has completed (it may be re-assigned a different IP address by the DHCP server). Automatic Reloading of the Web UI will not work if the address has been changed by the DHCP server. Therefore, a new web browser connection using the newly assigned IP address will need to be opened.

If the front panel LCD is configured to display network settings, the LCD window will show the newly assigned IP address.

When using a static-assigned IP address (or if the DHCP server did not assign a new IP address after the reboot), and as long the Web UI did not time-out during the update process (if it times-out, press the F5 key to refresh the connection), once the update is complete, you will now see the main page of the “new” Web UI design.

If you need to reconnect to the Web UI at any point, the login screen for the new Web UI design will now look like the following:

With the new Web UI design, the Upgrade Log with is located in the upper-right corner of the Home page. The top of this log should indicate “Successful”.

2.1.1 Required Repeat of Upgrade Process
IMPORTANT: The upgrade process must be performed a second time, if you are upgrading from a software version 5.1.4 or lower (as described in this chapter) AND your unit is equipped with a RES-SMT-GG receiver.

This is required to update the GNSS receiver firmware.

Caution: Note the second time performing the same update process does require the update file be uploaded into the unit again. The checkbox Force Update must NOT be checked.

With updateXXX.tar.gz in the update drop- down list after re- loading the update file, just select Perform Upgrade again and click Submit. The second time through the update process will be faster than the first time, as the receiver is the only item updated.

2.1.2 Confirming Successful Installation
Navigate to Tools > Upgrade/Backup. The following information should now be displayed:

2.1.3 Creating new Local Clock(s)
If you previously used a Local Clock (or several), manually re- generate these Local Clock(s), using the settings you wrote down in Step 1 above. For instructions see the main User Manual under MANAGING TIME > System Time > Local Clock(s).

2.2 Upgrading from V. ≥5.1.2 to a Newer Version

Note: Depending on the software currently installed on your unit, upgrading to the latest version may be a multi-step process. See “Determining the Correct Upgrade Procedure” on page 8 for more information.

The software upgrade process is performed using PC that is either on the same network as the NetClock 9400 appliance, or is connected directly to the NetClock 9400 via a network cable.
Note: In order to perform the software upgrade, the Web UI of the unit to be upgraded must be accessible from this particular PC. Once you downloaded the upgrade file onto a network PC, you can then transfer the file onto your NetClock 9400 unit, using the unit’s Web UI.

Note: Alternatively, you can also upgrade via Command Line Interface: In this case, the file must be transferred manually, using FTP/SFTP, to the NetClock 9400 directory home/spectracom.

During the time that the file is being uploaded into NetClock 9400, the unit will remain fully functional and accessible for other network PC’s.

Once the file transfer is complete, NetClock 9400 is performing the software upgrade (“Upgrade System”), during which the unit is configured: Normally, all current NetClock 9400 configurations are automatically saved and restored as part of the update process. During the “Upgrade System” process, the front panel LCDs will go blank, and the unit will not be operational until the upgrade process has completed.

1. Verify that LDAP has not been ENABLED inadvertently, by navigating to Management > Authentication > Actions: LDAP Setup: If you are not using LDAP, DISABLE the service (if correctly configured, the services can remain ENABLED during the upgrade process).

2. Download the NetClock 9400 ugrade file (updateXXX.tar.gz) from the Spectracom website—see also “Downloading the Upgrade Software Bundle” on page 12—to an accessible directory on your local Windows machine (such as C:/Temp).
3. Open the Web UI, and login. Then navigate to Tools > Upgrade/Backup.

4. Click the button Update System Software in the top-left corner of the Upgrade/Backup page:

5. Click Browse…, and navigate to the location to which you previously saved the update file (updateXXX.tar.gz) on your PC (such as C:/Temp). Select the file. The file name will appear next to the Browse… button.
6. Click Upload.

Note: When uploading files remotely via long distances, or when uploading multiple files via several browser windows simultaneously, the upload process may fail to complete. In this case, cancel the upload by clicking X, and go back to Step 2.

7. The file upload process may take several minutes. Once the file has been uploaded into your NetClock 9400, the directory of updatexxx.tar.gz (where xxx is the version) will be listed in the “File” dropdown, (The “down arrow” to the right-side of this field may need to be clicked, in order to see the file, if previous update files have been uploaded).

8. Ensure the correct file name (updateXXX.tar.gz)1 is selected in the “File” drop-down field.
9. Check the box next to Perform Upgrade to install the software update (or to downgrade to an earlier version).
Once this checkbox has been selected, two other checkboxes (Force Upgrade and Clean Upgrade) will become visible towards the bottom of the window. Note that these two checkboxes do not need to be selected for a standard upgrade to a newer version.

Force Upgrade — When checked, will force the software to install all update packages, even if it is already at the current revision, (for example, it is desired to install version 5.9.8, even though version 5.9.8 is already installed). The software will reinstall over the previously installed packages.
USE CASE: This checkbox needs be selected if it is ever desired to downgrade to a previous version of Software.

Clean Upgrade — When checked, will return the NetClock 9400 to its original factory configuration for the version of software being installed. (The Force Upgrade checkbox will be automatically selected when the Clean Upgrade checkbox is selected.)

Note: To perform a standard software upgrade, i.e. from an earlier software version to the latest version, only the checkbox Perform Upgrade needs to be selected.

During the System Upgrade process, the Upgrade Log window on the right-side of the browser will periodically have new entries asserted, indicating the update process is progressing.

Caution: Do not close the Web UI, or attempt to reboot the unit. The installation is in progress and may take several minutes to complete.

The Upgrade Status window will remain displayed during the upgrade progress, as long the browser is not refreshed (such as by pressing the keyboard F5 key, for instance) or as long as the web browser background is not clicked. If the page happens to be refreshed or the background clicked during the next few minutes while the update is being performed (causing the Status window to disappear), this Status window cannot be re-opened. However, the software update will continue to be performed with the window closed (the Upgrade Status window and the Web UI being open are not required for the update to be performed). The Status window will periodically report status change updates.

Note: If using a DHCP assigned IP address (instead of the unit having a statically assigned IP address), the IP address may change once the update has completed (it may be re-assigned a different IP address by the DHCP server).

Automatic Reloading of the web page will not work if the address has been changed by the DHCP server. Therefore, a new web browser connection using the newly assigned IP address will need to be opened.

If the front panel LCD is configured to display network settings, the LCD window will show the newly assigned IP address.

When using a static-assigned IP address (or if the DHCP server did not assign a new IP address after the reboot), and as long the web browser didn’t time- out during the update process (if it times-out, press the F5 key to refresh the connection), once the update is complete, you will now see the main page of the new web browser design.

Upgrade Log
The Upgrade Log is located in the upper- right corner of the Tools > Upgrade/Backup page of the Web UI. After completion of the upgrade process, the top of this log should indicate “Successful”.
2.2.1 Potential Need to Repeat Upgrade Process
IMPORTANT: The upgrade process must be performed a second time, if:
a. your unit is equipped with a RES-SMT-GG receiver, and you are upgrading from a software version 5.1.4 or lower
b. OR: If your unit is equipped with a u-blox M8T receiver, and you are upgrading from a software version older than 5.5.0 .

This is required to update the receiver firmware.

Caution: Note the second time performing the same update process does require the update file be uploaded into the time server again. The checkbox Force Update must NOT be checked.

With updateXXX.tar.gz1 in the update drop- down list after re- loading the update file, just select Perform Upgrade again and click Submit. The second time through the update process will be faster than the first time, as the receiver is the only item updated.

2.2.1.1 u-blox M8T: Upgrading to Version 5.9.8:

1. Update to software version 5.9.8.
2. The final update status page after reboot will show the u-blox M8T failed to update to version 3.0.1 TIM 1.10.
3. Re-run the update again in order to update the u-blox M8T. Should you see a version other than 3.0.1 TIM 1.10 displayed, the upgrade was not successful. Proceed as follows:

a. Reset the receiver from the Web UI: Navigate to Interfaces > References:
GNSS Reference, and click the GEAR button next to the GNSS Reference. In the GNSS 0 window, locate the Reset Receiver box, check it, and click Submit.
b. If the version persists, reboot NetClock 9400.
c. If it still persists, run the Release 5.9.8 update again.

2.2.1.2 RES-SMT-GG: Upgrading to Version 5.9.8:
1. Update to software version 5.9.8.
2. The final update status page after reboot will show the u-blox M8T failed to update to version 1.9.
3. Re-run the update again in order to update the RES-SMT-GG. Should you see a version other than 1.9 displayed, the upgrade was not successful. Proceed as follows:
a. Reset the receiver from the Web UI: Navigate to Interfaces > References: GNSS Reference, and click the GEAR button next to the GNSS Reference. In the GNSS 0 window, locate the Reset Receiver box, check it, and click Submit.
b. If the version persists, reboot NetClock 9400.
c. If it still persists, run the Release 5.9.8 update again.

2.2.2 Confirming Successful Installation

Note: You will need to log into the Web UI, using your login account information

Navigate to Tools > Upgrade/Backup. The new System software version should be displayed, and the new GNSS Receiver version should be displayed (Trimble RES- SMT-GG: SW V1.9; u-blox M8T: SW V3.0.1 TIM 1.10.)

APPENDIX

Appendix

3.1 Upgrading via CLI
It is possible perform a software upgrade via a Command Line Interface, rather than using the Web UI, for example for scripting software updates.

Starting in Archive software version 4.8.8, the software update can be initiated using a CLI command (issued via telnet, SSH or the front panel Serial port), instead of using the web browser, if desired. This entails performing an FTP/SCP transfer of the software update file into NetClock 9400’s /home/spectracom directory and then issuing the sysupgrade CLI command to initiate the software upgrade.

Note: IMPORTANT: When transferring the update file using either FTP or SCP (instead of uploading it using the web browser), make sure the Update file is transferred using BINARY mode (SCP transfer is preferred, because it always transfers using Binary mode). Otherwise, this file will likely be altered during the file transfer, preventing the updater from being able to extract it. The following error message will be asserted into the Update log if the Update file is altered/can’t be extracted: “ERROR (-1) – Failure while unpacking Upgrade Bundle (SWUE)”.

The syntax for issuing the sysupgrade command is:
Standard upgrade (Such as upgrading versions 4.8.8 to 4.8.9, for example): “sysupgrade” followed by the upgrade file name (Example: sysupgrade update489.tar.gz).

Forced upgrade (Such as downgrading versions 4.8.9 to 4.8.8, for example, but can also be used with Standard upgrades, also): “sysupgrade force” followed by the upgrade file name (Example: sysupgrade force update489.tar.gz).

Clean upgrade (Such as first performing a Forced upgrade from 4.8.8 to 4.8.9, for example. Then automatically resetting the NTP server back to factory default settings and deleting all log files): “sysupgrade clean” followed by the upgrade file name (Example: sysupgrade clean update489.tar.gz).

3.2 Saving/Restoring Configuration Files
Important note about restoring old configuration files
Due to fairly significant changes to the system configuration files from system software versions prior to version 5.9.8, it is not recommended to perform a configuration restore with 5.9.8 software installed, from a configuration save that was performed in a NetClock 9400 with versions 4.8.9 or earlier installed. If a configuration restore from versions 4.8.9 or below software is performed on a version 5.x.x time server, a ‘clean’ will be required to be performed via the front panel keypad thereafter to reset the NTP server to the factory default settings for the installed version.

In general, due to possible changes to configuration files from one version to another, if you wish to have a configuration backup file saved, we recommend performing a new “configuration save” after each new software update is performed, to replace the earlier configuration bundle. This will ensure that if a configuration restore is performed, the configs in the captured file will be identical to the ones in the NTP server.

3.3 Software Update Log Entries
Software update log entries, such as upgrades that have already been performed, or an error occurring during the update process, are placed in the Update Log (Tools > Logs page of the Web UI). Please refer to this log if you have any problems with the software update process (such as if the message “Upgrade Failure” is displayed, for instance).

3.4 Downgrading the SW to a Previous Version
If your current software is below 5.9.6, the software can be downgraded to previous versions 5.0.0 or higher (it is not recommended to downgrade to versions 4.8.9 or below from versions 5.0.0 and above). The downgrade process is the same as an upgrade, except an earlier version update bundle is selected during the process and the update needs to be “Force Updated” (to override the version checking that normally occurs).

Note: It is not possible to downgrade from 5.9.6 to any earlier version due to significant core package updates. All versions following 5.9.6 cannot downgrade to any software version earlier than 5.9.6.

Note: Due to incompatibilities between later and earlier configuration files, a “Clean Upgrade” is also required to be performed during the software “downgrade” process (the unit will need to be reconfigured as desired, once it’s been downgraded to the desired, earlier version).

Note: You will not be able to apply a Saved configuration file from a later version of software to any earlier, downgraded version of software to restore the configurations. However, a saved config file previously performed when it was at the earlier version can be safely reapplied as desired to restore configs.

Downgrading to an earlier version using the newer (black- /charcoal background) Web UI:

To simultaneously downgrade and ‘Restore Factory Configuration”:

1. Navigate to the Tools > Upgrade/Backup page.
2. Press Update System software (on the left side of the screen, under Actions).
3. Verify the desired update bundle you wish to downgrade to is in the File drop-down. If not, press Upload New File and browse to where the earlier update bundle is stored. Upload the bundle into the unit.
4. Select the Perform Upgrade checkbox in the menu that opens, which will expand the menu down to display two additional checkboxes.
5. Select the desired Update bundle version which you wish to downgrade to.
6. Select also the Force Upgrade and Clean Upgrade checkboxes, before clicking Submit (as shown in the screenshot below) to begin the downgrade. The Clean Upgrade checkbox resets all of the configurations back to factory default, as needed to occur when downgrading to an earlier software version.
   The software downgrade will take several minutes to complete.

Note: If the software was downgraded back to a version prior to version 5.1.0, the “classic interface” will be displayed after logging back in, once the downgrade has completed.

1. Once downgraded, reconfigure the unit’s settings as desired, or restore a previously Saved config file from the version the software has been downgraded to.
Downgrading to an earlier version using the “classic interface” Web UI

To simultaneously downgrade and Restore Factory Configuration, in addition to selecting the Update System, and Force Update checkboxes, also select the Restore Factory Configuration checkbox before clicking Submit (as shown in the screenshot below). The software downgrade will take several minutes to complete.

The Restore Factory Configuration checkbox resets all of the unit’s configurations back to the factory default settings.

Note: If the software was downgraded back to a version prior to version 5.1.2, the “classic” interface will be displayed after logging back in, once the downgrade has completed.

Reconfigure the settings as desired, or restore a previously saved config file from the version the software has just been downgraded to.

3.5 “Upgrade Failure” (V. 5.0.2 to a Newer Version)
If the Update process returns “Upgrade Failure” (as shown below), the software update process was not successful

If this happens, review the entries in the Update and System logs.

Applying the same version already installed or downgrading to an earlier version of software without select the “Force Update” checkbox, in addition to selecting the “Update System” checkbox can cause the upgrade to fail. Make sure to select “Force update when applying the same or earlier version of software.

The Update log may contain the following entry: “Error (-1) Failure while unpacking Upgrade Bundle” / “Problem unpacking NWP bundle” (as shown below):

Likely causes for this error message in the Update log

The update file may be corrupt (preventing it from being able to be extracted in the time server). Run MD5 checker against the update file to verify file integrity. Spectracom provides the MD5 file for each software update file.

Too many Update Bundles are stored in the time server. Delete previous update bundles (such as update489, for instance).

Once a software update has been applied, the update bundle can be deleted (the bundles only need to be stored in the time server to alleviate the need to transfer them again to perform a software downgrade. Otherwise, they can be safely deleted without affecting the time server). Having too many upgrade files saved can prevent the update file being applied from being able to extract.

To delete earlier update files, select each one individually in the drop- down, check only the “Delete Update File” checkbox in the screen where you normally select “Update File”. Then press Submit. This will delete the selected update file.
Then run the update process again.
3.6 “Upgrade Failure” (V. ≥5.1.2 to a Newer Version)
If the Update process returns “Upgrade Failure” (as shown below), the software update process was not successful. Note that starting the update process again after it is already been started will result in an “upgrade failure” of the subsequent update process, while the first one is still being performed in the background.

If this happens, review the entries in the Update and System logs.

1. The time server may be retaining earlier upgrade bundle files which were applied and are no longer needed. Previous update bundles should be deleted. For more information, see “Deleting Old Update Files” on page 11.
2. Applying the same version already installed or downgrading to an earlier version of software without select the “Force Update” checkbox, in addition to also selecting both the “Force Upgrade” and “Clean Upgrade” checkboxes can cause the upgrade to fail. Make sure to select the “Perform Upgrade”, “Force Upgrade” and “Clean Upgrade” checkboxes when applying the same or earlier version of software.
3. The Update log may contain the following entry: “Error (-1) Failure while unpacking Upgrade Bundle” / “Problem unpacking NWP bundle”

Likely causes for this error message in the Update log:
The update file may be corrupt (preventing it from being able to be extracted in the time server). Run MD5 checker against the update file to verify file integrity. Spectracom provides the MD5 file for each software update file.

Too many Update Bundles are stored in the time server. Delete previous update bundles (such as update489, for instance).

Once a software update has been applied, the update bundle can be deleted (the bundles only need to be stored in the time server to alleviate the need to transfer them again to perform a software downgrade. Otherwise, they can be safely deleted without affecting the time server). Having too many upgrade files saved can prevent the update file being applied from being able to extract.

To delete earlier update files, select each one individually in the drop- down, check only the checkbox Delete Upgrade File in the screen where you normally select “Update File”. Then click Submit. This will delete the selected update file. Then run the update process again.

3.6.1 Failure of Component Upgrades
Certain conditions may cause your overall upgrade status to be listed as Complete, even though some components show Failed upgrades.

Note: One known cause of this problem is in units currently running software version 5.8.7 and upgrading to a newer version.

If a component such as an option card fails your first attempt at upgrade:

• Upload the upgrade file again
• Repeat upgrade
• Note component status

If all Failed messages have cleared, the update has been successful with all expected materials.

If you receive additional Failed messages, it is recommended that you contact Technical support for additional insturction or infomation.
