The following lists the individual Dell S4048T–ON system hardware components that are available to order:

Table 2. Hardware Components Available to Order

Fan with airflow from I/O side to PSU side (red — normal air flow direction)

Fan with airflow from PSU side to I/O side (blue — reversed air flow direction)
AC or DC power supply with airflow from I/O side to PSU side
AC or DC power supply with airflow from PSU side to I/O side

NOTE: Fan modules and power supplies are field replaceable units.
NOTE: All fans and PSUs must have the same airflow direction. If you mix the airflow direction, the switch detects the discrepancy, issues an alarm, and may auto-shutdown to avoid heat damage to components. You must correct the mixed airflow direction.

Supported Software

The following software is supported with this platform:

NOTE: For information on non-Dell OS versions, see the Release Notes for the Hardware Platform S4048T–ON.

New Dell Networking OS Version 9.14(2.20) Features

The following features are integrated into the Dell Networking 9.14.2 branch through this release:
None.

Restrictions

• You can use non-Dell qualified cables, adapters, and optics in a S4048T-ON switch, but Dell Networking does not guarantee their performance as the S4048T-ON 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:
  %S4048TLC0640:8 %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.

• Prerequisite steps to upgrade the Dell Networking OS from earlier version to 9.14.2.0 or later:

1. Uninstall the older version of the Open Automation (OA) package
2. Upgrade the Dell Networking OS to 9.14.2.0 or later version
3. Install the following OA packages from the respective upgraded version:
   a. SmartScripts
   b. Puppet
   c. Open management infrastructure (OMI)
   d. SNMP MIB

Prerequisite steps to downgrade the Dell Networking OS from 9.14.2.0 or later to the earlier version:

1. Uninstall the OA package of 9.14.2.0 or later version
2. Downgrade the Dell Networking OS to an earlier version
3. Install the respective OA package from an earlier version

For more information about installing, uninstalling and upgrading the Dell Networking OS and OA package, refer the respective Dell System Release Notes.

• If you downgrade the Dell Networking OS version from 9.14.2.20 to 9.11.0.0 or any older versions, the system displays the following error message even though there is no functional impact:

• Before downgrading, save the current configuration and then remove the CDB files (confd_cdb.tar.gz.version and confd_cdb.tar.gz). To remove the files, use the following steps:

• In a VXLAN scenario, hybrid port is not supported.

• While deploying the system in the normal-reload mode in BMP configuration, use the ip ssh server enable command at the beginning of the startup configuration if the write memory command is used at the end of the configuration.

• The following features are not available in the Dell Networking OS from version 9.7(0.0):

  • PIM ECMP
  • Static IGMP join (ip igmp static-group)
  • IGMP querier timeout configuration (ip igmp querier-timeout)
  • IGMP group join limit (ip igmp group join-limit)

• You can use the negotiation auto command to turn auto-negotiation on or off only on fiber interfaces operating at 1G speed.

• If you use the interface range command to select multiple interfaces that are added to the management VRF, the ipv6 address command does not display the autoconfig option. You can configure the autoconfig command on individual interfaces.

• If you use the interface range command to select multiple interfaces that are added to the management VRF, the ipv6 nd command displays the following options but they do not take effect if you use them:

  • dns-server
  • hop-limit
  • managed-config-flag
  • max-ra-interval
  • mtu
  • other-config-flag
  • prefix
  • ra-guard
  • ra-lifetime
  • reachable-time
  • retrans-timer
  • suppress-ra

• REST API does not support AAA authentication.

• Do not configure the vxlan-instance command on the port, which is configured with the portmode hybrid command. Do not configure the vxlan-instance enabled port as a member of VLAN, which does not have VXLAN-VNI configuration.

• Half-Duplex mode is not supported.

• When FRRP is enabled in a VLT domain, no flavor of Spanning tree should concurrently be enabled on the nodes of that specific VLT domain. In essence FRRP and xSTP should not co-exist in a VLT  environment.

Changes to Default Behavior and CLI Syntax

The following behavior and CLI changes are applicable to the S4048T–ON switch with Dell Networking OS version 9.14(2.20): None

Documentation Corrections

This section describes the errors identified in the current release of the Dell Networking OS.

• The router bgp command allows you to configure only one L3 interface with an IPv4 address. The Configuration guide does not mention this limitation and will be corrected in the next release of the guide.

Deferred Issues

Known S4048T–ON 9.14(2.20) Software Issues

The following caveats are open in Dell Networking OS version 9.14(2.20): None

Upgrading the sub-components

1. It is recommended to upgrade the sub-components in the following order and reload the switch where necessary, before
   proceeding with the next sub-component upgrade.

2. Upgrade the BIOS or Boot-selector – using the upgrade boot bootselector-image stack-unit 1 booted command.

3. Upgrade the GRUB or Bootflash – using the upgrade boot bootflash-image stack-unit 1 booted command.

4. Upgrade the CPLD – using the upgrade fpga-image system cpld stack-unit 1 booted command.

Upgrade the BIOS or Boot Selector

To upgrade the BIOS or Boot Selector from Dell Networking OS, perform the following steps:

1. Upgrade the S4048T-ON Boot Selector image.

EXEC Privilege Mode

1. upgrade boot bootselector-image stack-unit [ | all] Dell Networking OS version 9.14(2.20) requires S4048T-ON Boot Selector image version or higher. The booted option is used to upgrade the Boot Selector image to the image version packed with the loaded Dell Networking OS image. The Boot Selector image version packed with the loaded Dell Networking OS can be found using the show os-version command in EXEC Privilege mode.
2. . Reload the unit. EXEC Privilege Mode reload
3. Verify the Boot Selector image. EXEC Privilege Mode
   show system stack-unit

Upgrade the GRUB or Boot Flash

To upgrade the GRUB or Boot Flash from Dell Networking OS, perform the following steps:

1. Upgrade the S4048T-ON Boot Flash image.
   EXEC Privilege Mode upgrade boot bootflash-image stack-unit [ | all] [booted | flash: | ftp: | scp: | tftp: | usbflash:]

Upgrade the CPLD

The S4048T-ON system with Dell Networking OS Version 9.14(2.20) requires System CPLD revision 12 and Master CPLD
revision 13.
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.

Verify that a CPLD upgrade is required

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 1 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.
To upgrade the CPLD image on S4048T-ON, 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.
   You can alternatively power cycle the switch using the power-cycle stack-unit <1-6> command as follows:

3. The CPLD version can be verified using show revision command output:
   EXEC Privilege Mode
   show revision

NOTE: Do not power off the system while FPGA upgrade is in progress. For any queries, contact technical support.
