Document Revision History
Table 1. Revision History

New Dell Networking OS Version 9.14(2.14) Features
The following features are integrated into the Dell Networking 9.14.2 branch through this release:

• None

Changes to Default Behavior and CLI Syntax

• If you are upgrading from an earlier OS9 version to 9.14.2.x, ensure you first upgrade to version 9.13.0.0 before upgrading to the required version of 9.14.2.x to prevent any issues during the upgrade procedure.

Restrictions

• You can use non-Dell qualified cables, adapters, and optics in a S6000 switch, but Dell Networking does not guarantee their performance as the S6000 does not support non-Dell qualified transceivers of 25G and above. If you insert
  a non-Dell qualified transceiver of 25G and above into a SFP28, QSFP+, or QSFP28 port, the switch places the interface in an error-disabled (operationally down) state and generates a syslog message, such as: %S6000LC0640:8 %IFAGT-2-TRANSCEIVER_UNSUPPORTED_ERROR: Transceiver in slot 1 port 49 unrecognized, putting interface in operational-down state.

To verify the error-disabled status of an interface, enter any of the following show commands.

NOTE : If you are using Bare Metal Provisioning (BMP), refer to the Bare Metal Provisioning chapter in the Dell Networking OS Configuration Guide or the Open Automation Guide.

Manual Upgrade Procedure
Follow these steps carefully to upgrade your S6000 systems:

1. Dell Networking recommends that you back up your startup configuration and any important files and directories to an external media prior to upgrading the system.

2. Upgrade the Dell Networking OS in flash partition A: or B: EXEC Privilege Mode
   upgrade system [flash: | ftp: | stack-unit <0-5 | all> | tftp: | scp: | usbflash:] [A: |B:]

3. In case of a stack setup, upgrade the Dell Networking OS for the stacked units.
   EXEC Privilege Mode
   upgrade system stack-unit [0-11 | all] [A: | B:] If A: is specified in the command, the Dell Networking OS version present in Management unit’s A: partition will be pushed to the stack units. If B: is specified in the command, the Management unit’s B: will be pushed to the stack units. Upgrade of stack units can be done on individual units by specifying the unit id [0-5] or on all units by using all in the command.

4. Verify the Dell Networking OS has been upgraded correctly in the upgraded flash partition.
   EXEC Privilege Mode
   show boot system stack-unit [0–5 | all]

5. Upgrade the S6000 Boot Flash and Boot Selector images.
   EXEC Privilege Mode
   upgrade boot [all | bootflash-image | bootselector-image] stack-unit [0-5 | all] [booted | flash: | ftp: | scp: | tftp: | usbflash:] Dell Networking OS version 9.14(2.14) requires S6000 Boot Flash image version 3.1.1.7 and Boot Selector image version 3.1.0.3. The Boot Flash and Boot Selector images can be upgraded together by selecting all in the command. If the user wishes to upgrade Boot Flash image or Boot Selector image separately, the options bootflash-image or bootselector-image needs to be given separately in the command. The booted option is used to upgrade the Boot flash and Boot Selector images to the image versions packed with the loaded Dell Networking OS image. The Boot Flash and Boot Selector image versions packed with the loaded Dell Networking OS can be found using the show os-version command in EXEC PRIVILEGE mode.
   NOTE : The Boot Flash version packed in Dell Networking OS 9.14(2.14) for S6000 system is 3.1.1.7. Upgrade of Boot Flash to version 3.1.1.7 is not mandatory for proper functioning of the system.

6. Change the Primary Boot Parameter of the S6000 to the upgraded partition A: or B: CONFIGURATION Mode boot system stack-unit [0–5 | all] primary system: [A: | B: | tftp: | ftp:]

7. Save the configuration so that the configuration will be retained after a reload using write memory command. EXEC Privilege Mode write memory

8. Reload the unit.
   EXEC Privilege Mode reload

9. Verify the S6000 has been upgraded to the Dell Networking OS version 9.14(2.14).
   EXEC Privilege Mode show version

10. Verify that the S6000 has been upgraded to the latest Boot Flash and Boot Selector images
    EXEC Privilege Mode
    show system stack-unit [0-5]

SMARTSCRIPTS

Upgrading the CPLD

The S6000 system with Dell Networking OS Version 9.14(2.14) requires System CPLD revision 10, Master CPLD revision 12, and Slave CPLD revision 10.
Verify that a CPLD upgrade is required

NOTE : If your CPLD revisions are higher than the ones shown here, DO NOT make any changes. If you have questions regarding the CPLD revision, contact technical support.
Use the following command to identify the CPLD version:

Use the following command to view CPLD version that is associated with the Dell Networking OS image:

**** Upgrading the CPLD Image

NOTE: The upgrade fpga-image stack-unit 0 booted command is hidden when using the FPGA Upgrade feature in the CLI. However, it is a supported command and will be accepted when entered as documented.
NOTE : Ensure that the BIOS version is 3.1.0.3 or above. You can verify this version using the show system stack-unit 0 command.

To upgrade the CPLD image on S6000, follow these steps:

1. Upgrade the CPLD image.
   EXEC Privilege Mode upgrade fpga-image stack-unit booted

2. Power cycle the system physically. Switch off the system by unplugging the power chords from the REAR PSUs and wait until the PSU FAN–REAR STATUS LED is completely OFF.
   NOTE : Do not switch on the system with PSU–REAR LED glowing AMBER.

3. Switch on the system and wait for the Dell prompt. The CPLD version can be verified using the show revision command.
   EXEC Privilege Mode show revision NOTE : Do not power off the system while FPGA upgrade is in progress. For any queries, contact technical support

VLT Upgrade Procedure

Follow this procedure to upgrade the system from release 9.4(2.8) to the latest version in a VLT setup:

1. Upgrade the system-flash partition A or B with the new image on both VLT peers.On both the VLT peers, set Primary boot parameter to boot the system from upgraded system flash partition [A or B].You can enter one of the following options:flash— Copies from flash file system (flash://filepath).ftp — Copies from remote file system (ftp://userid:password@hostip//filepath).scp — Copies from remote file system (scp://userid:password@hostip//filepath).tftp — Copies from remote file system (tftp://hostip/filepath).
   EXEC Privilege Mode
   upgrade system [flash: | ftp: | scp: | tftp: | usbflash:] [A: | B:]

2. Reload or power-cycle one of the VLT peers (For Example, Peer 2).
   EXEC Privilege Mode reload or power cycle

3. Wait for Peer 2 to come up; VLT adjacency will be established. (Peer 2 – new image and Peer 1 – old image).

4. Wait for the Peer 2 to bring up all VLT LAG ports. Use the command show vlt detail to confirm all VLT ports in the local chassis are active.
   EXEC Privilege Mode show vlt detail

5. Following upgrade, use the write memory command to save the running-config to memory.
   EXEC Privilege Mode write memory

6. Ensure both the nodes are now forwarding traffic.

7. When all VLT ports are active on the Peer 2, repeat steps 2 through 5 for the Peer 1.
