request system firmware optics update (Junos OS Evolved)

Syntax (PTX Series)

Description

After installing the junos-evo-install*.iso package with the request system software add command and rebooting your system, use the request system firmware optics update command to update the firmware for CMIS 4.0 optics modules. This upgrade may cause the link to go down, the module to be re-initialized, and traffic to be lost. Do not apply any configuration to the optics modules during the upgrade.

Note: If you need to upgrade third-party CMIS 4.0 optics modules, you need to obtain the firmware file from your supplier first. Then copy this file to the router's filepath /var/tmp before attempting to update the firmware for the optics modules.

The firmware upgrade uses the CDB commands defined in the CMIS 4.0 specification. The host software assumes that the optics hardware and firmware complies with the CMIS 4.0 CDB support definitions and that the optics vendor does not deviate from the standard. If the optics vendor does not implement the CDB support as per the standard, then a firmware upgrade may fail and lead to firmware corruption on the optics module.

For more information about the CMIS 4.0 specification, see Common Management Interface Specification.

The operating system does not fetch any PM metrics from the optics EEPROM during the firmware upgrade. Therefore, PM bins and DOM output are not accurate during the firmware upgrade.

Use the show chassis pic fpc slot-number pic slot-number command to look up part numbers and port numbers.

Some examples of ways to combine the command options:

  • Update multiple optics modules with the same part number within the specified FPC: request system firmware update optics fpc-slot slot-number firmware-path path part-num part-number.

  • Update multiple optics with the same part number within the specified FPC and PIC: request system firmware update optics fpc-slot slot-number pic-slot slot-number firmware-path path part-num part-number.

  • Update a single optics module within the specified port number - request system firmware update optics fpc-slot slot-number pic-slot slot-number port port-number firmware-path path

If you do not specify a path, then the command uses the firmware bundle that was contained within the junos-evo-install*.iso installation package.

Options

The fields that are valid may vary depending on the platform and software release.

firmware-path path

Path to the firmware tar file, usually /var/temp/file-name.bin.
fpc-slot slot-number

Slot number of FPC.
part-number

Optics module part number. Use the show chassis pic fpc slot-number pic slot-number command to look up the part number.
port port-number

Slot number of the port. Use the show chassis pic fpc slot-number pic slot-number command to look up the port number.
pic-slot slot-number

Slot number of the PIC.
password password Password to unlock the firmware download. Range is 0 to 2147483647. For third-party optics modules, you need to get this password from your supplier.
