    Upgrading the Re-timer Firmware on a UFM6

    Use this procedure to upgrade the re-timer firmware on UFM6 modules. This procedure is supported in releases 4.3 and higher.

    The UFM6 contains re-timer firmware on each of the dual-mode ports (client ports 1, 2, 6, 7). When you upgrade the software from a release compatible with one re-timer version to a release compatible with another re-timer version, the system raises a Firmware Upgrade Required (firmUpgrdReqd) alarm. To clear the alarm, you should upgrade the re-timer firmware on all UFM6 modules in the system.

    Table 1 shows the different re-timer versions available and the software releases that they are compatible with.

    Table 1: UFM6 Re-timer Versions

    Re-timer Version

    Packaged with Software Release

    Compatible with Software Release

    D013

    4.1, 4.2

    D015

    4.3 and higher

    4.1, 4.2, 4.3, and higher

    For example, if you upgrade your system from release 4.1 or 4.2 to release 4.3, you should also upgrade the re-timer firmware to version D015 on the dual-mode ports on all applicable UFM6 modules.

    A dual-mode port running an older version of the re-timer firmware behaves as follows in a system running a software release that is not compatible with the older version of the re-timer firmware:

    • All existing interfaces and cross-connects associated with that port continue to run normally.
    • New interfaces cannot be created on that port.

    You can upgrade the re-timer firmware on the UFM6 in one of two ways:

    • Reseat or perform a cold reload of the UFM6. Once the UFM6 boots back up, it will automatically upgrade the re-timer firmware on all dual-mode ports to the latest version. This automatic upgrade also occurs if you insert a UFM6 that is running an older version of the re-timer firmware into the chassis. Note that you can cause a cold reload without explicitly issuing the cold reload command. For example, changing the administrative status of the UFM6 from up to down and back to up causes a cold reload of the module.
    • Upgrade the re-timer firmware manually using CLI commands. The remainder of this section describes this procedure.

    Note: Upgrading the re-timer firmware is service affecting on the port where the firmware is being upgraded.

    Warning: Once the re-timer upgrade has started on any port, you must let the upgrade proceed to completion and not issue any commands that interfere with the upgrade. Without limiting the generality of the foregoing, this includes warm and cold reloads (and removal) of the containing UFM6, system software upgrades and rollback, CMM firmware upgrades, system database restoration, CMM commissioning, and CMM replacement.

    1. Determine the UFM6 modules that require re-timer firmware upgrades.

      For example:

      bti7800# show system firmware retimer
      Module            Port Number      Device       Firmware
      ----------------  ---------------  -----------  ---—-------–-–-----—------
      ufm:1/14          1                Retimer      D013 **Firmware Mismatch**
      ufm:1/14          2                Retimer      D013 **Firmware Mismatch**
      ufm:1/14          6                Retimer      D013 **Firmware Mismatch**
      ufm:1/14          7                Retimer      D013 **Firmware Mismatch**
      

      Ports that require an upgrade are shown with a **Firmware Mismatch**.

    2. Disable the port on which you want to upgrade the re-timer firmware.

      For example:

      Note: This is service affecting for the port.

      bti7800# config
      Entering configuration mode terminal
      bti7800(config)# equipment chassis:1 module ufm:1/14 transceiver qsfp:1/14/1/2 admin-status down
      bti7800(config-transceiver-qsfp:1/14/1/2)# commit
      Commit complete.
      bti7800(config-transceiver-qsfp:1/14/1/2)# end
      bti7800#

      If you want to upgrade the re-timer firmware on more than one port, repeat this step for the other ports.

    3. Upgrade the re-timer firmware.

      For example:

      bti7800# system upgrade firmware retimer module ufm:1/14 port 2

      If you want to upgrade the re-timer firmware on all ports on the module, use the system upgrade firmware retimer module ufm:1/14 port all command but be sure to disable all dual-mode ports on the UFM6 first.

    4. To see which ports are being upgraded, check the outstanding conditions. A Firmware Upgrade In Progress (firmUpgrdInProg) condition is raised against the port during the upgrade. For example:
      bti7800# show conditions | inc rtmr
      rtmr:1/14/1/1                                   firmUpgrdInProg          non-alarmed   2017-05-17T17:29:24-04:00      not-reported        false               Firmware upgrade in progress
      rtmr:1/14/1/2                                   firmUpgrdInProg          non-alarmed   2017-05-17T17:29:24-04:00      not-reported        false               Firmware upgrade in progress
      rtmr:1/14/1/7                                   firmUpgrdInProg          non-alarmed   2017-05-17T17:29:24-04:00      not-reported        false               Firmware upgrade in progress
      

      Note: A re-timer upgrade can take 10 minutes or more to complete.

      Warning: Once the re-timer upgrade has started on any port, you must let the upgrade proceed to completion and not issue any commands that interfere with the upgrade. Without limiting the generality of the foregoing, this includes warm and cold reloads (and removal) of the containing UFM6, system software upgrades and rollback, CMM firmware upgrades, system database restoration, CMM commissioning, and CMM replacement.

      After the upgrade is complete, the firmUpgrdInProg condition is cleared on the port. If the re-timer firmware on the dual-mode ports on all UFM6 modules have been upgraded to the proper version, the firmUpgrdReqd alarm is cleared.

      If the upgrade fails, a Firmware Upgrade Failed (firmUpgrdFail) alarm is raised against the port. In this situation, reissue the upgrade command.
