This article introduce the method to upgrade BIOS firmware for a virtual-chassis setup.

Perform the following steps to upgrade the VC firmware:

• Add the jfirmware package in primary Routing Engine (RE).

         user@host> request system software add /var/tmp/jfirmware-ex.tgz

• Upgrade the BIOS and check the status in primary RE.

         user@host> request system firmware upgrade jfirmware bios
         user@host> request system firmware upgrade jfirmware bios progress

• Upgrade the System CPLD and check the status in primary RE.

         user@host> request system firmware upgrade jfirmware cpld sys
         user@host> request system firmware upgrade jfirmware cpld sys progress

• Upgrade the CPU CPLD and check the status in primary RE.

user@host> request system firmware upgrade jfirmware cpld cpu progress

Repeat the steps 2, 3, and 4 in each member of the VC by logging in to the member. Use the request session member <fpc-slot> command to log in.

Power cycle or reboot all the members of the VC. Reboot the members one by one after the upgrade is successful after Step 4 depending on either CPLD or BIOS upgrade.
