The Switch 7750 do not support the spare mode.
■
When a module is almost fully loaded and a new PD is added, the switch will
■
respond to the PD according to the PoE management mode. For details, see
"Setting PoE Management Mode" on page 720.
In auto mode, when the switch is reaching its full load in supplying power, the
■
switch decides whether to supply power to remote PDs on a port based on the
port priority. Note that the switch can compare only the priority of ports on the
same module.
The online upgrading of PSE processing software can update the processing
software or repair the software if it is damaged. After downloading the PSE
processing software to the Flash of the switch, you can perform the following
configuration. Refer to "File System Management" on page 791 for how to
download the PSE processing software.

The refresh update mode is to upgrade the valid software in the PSE through
■
refreshing the software, while the full update mode is to delete the invalid
software in PSE completely and then reload the software.
Generally, the refresh update mode is used to upgrade the PSE processing
■
software.
When the PSE processing software is damaged (that is, all the PoE commands
■
cannot be successfully executed), you can use the full update mode to
upgrade and restore the software.
When the upgrading procedure in refresh update mode is interrupted for
■
some unexpected reason (such as power-off) or some errors occur, if the
upgrade in full mode fails after restart, you must upgrade in full mode after
power-off and restart of the device. In this way, the upgrade procedure
succeeds.
After the above configuration, execute the display command in any view to see
the operation of the PoE feature and verify the configuration.
