Syntax
Release Information
Command introduced in Junos OS Release 12.1 for EX Series switches.
Description
Upgrade the PoE controller software on switches and line cards.
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.
For all Virtual Chassis except EX8200 Virtual Chassis, execute this command on the master. The master itself does not have to support PoE for this command to work—for example, you can execute this command on the master of a mixed EX4200 and EX4500 Virtual Chassis when the master is an EX4500 switch. On an EX8200 Virtual Chassis, you must execute this command on the member switch, not the master XRE200 External Routing Engine.
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.
You cannot downgrade the PoE controller software.
 | Note: When you enter the request system firmware upgrade poe command, a message advises you that the controller software upgrade has started and that it will take about 10 minutes to complete. This message appears even if the FPC you have specified does not have a PoE controller or if the PoE controller software is up-to-date. To determine whether or not the controller software upgrade has actually started, use the show poe controller command. |
| Note: While the upgrade is in progress, power to the powered devices is not guaranteed. We recommend that you upgrade the controller software during a regularly scheduled maintenance window. |
