request system firmware upgrade jfirmware poe
Syntax
request system firmware upgrade jfirmware poe file jfirmware-file fpc-slot (number | all-members) <poe-at-firmware | poe-bt-firmware>
Description
Upgrade the PoE controller software on switches and line cards through jfirmware.
The Junos OS image running on the switch contains a copy of the PoE controller software. This command compares the Junos OS version with the version of the software running on the PoE controller. If the Junos OS version is a more recent version, the command downloads the more recent version to the controller.
We recommend that all members of a Virtual Chassis run the same version of the PoE controller software.
Upgrading the controller software can take up to 10 minutes.
Use the show poe controller
command to monitor the progress of the software download.
If you load a version of the Junos OS software that is not compatible with the PoE firmware version, a major alarm will be raised. See Table 1 for firmware compatibility.
