Upgrading Firmware on the CFP2-DCO-T-WDM-1 Transceiver

Before you upgrade the firmware package, ensure that a previous version is not installed on the router. For more information, see Before You Begin Installing or Upgrading the Firmware.

1. Run the show system firmware command to view the list of components installed on the router and the firmware version for each component.
   user@host> show system firmware

   FPC 4       ROM Monitor 0  0   13.3.1              OK
   FPC 4       MPCS(0)        2   0.24.0              OK
   Routing Engine 0 RE BIOS        0   1.18           OK
   Routing Engine 1                0   1.18           OK
   

   The output of the show system firmware command displays the current firmware version of the transceiver as .0 and the available firmware version as 1.0.

2. To upgrade the firmware of the transceiver, use the request system firmware upgrade pic command. For example, to upgrade the firmware version of the transceiver from .0 to 1.0, specify the FPC slot (or MPC slot) and PIC slot (or MIC slot) in the command.
   user@host> request system firmware upgrade pic pic-slot 1 fpc-slot 0 tag 20

   Perform indicated firmware upgrade ? [yes,no] (no) yes

   Confirm that you want to perform the firmware upgrade by typing Yes so the firmware upgrade is initiated.

3. To monitor the progress of the upgrade, use the show system firmware command. During the installation process, the status of the transceiver changes to PROGRAMMING. When the installation process is complete, the status of the transceiver changes to UPGRADED SUCCESSFULLY.

   Note: The amount of time it takes to upgrade firmware varies depending on the component.

   Note: If the installation process fails, delete the firmware package by using the request system software delete firmware-package-name command. Reinstall the firmware package by following the procedure for installing the firmware package and then upgrade the firmware package.

4. Restart the FPC that the transceiver is installed in by using the request chassis fpc fpc-slot restart command.
5. Confirm that the firmware upgrade was successful by using the show system firmware command and verifying the correct firmware version appears.
6. (Optional) After the firmware upgrade is successfully completed, uninstall the firmware package from the router by using the request system software delete command.
