Poe Update - H3C s3100 series Command Manual

The switch disables the PoE feature on all ports when its internal temperature exceeds 65°C (149°F) for
self-protect, and restores the PoE feature settings on all its ports when the temperature drops below
60°C (140°F).
By default, PoE over-temperature protection is enabled on the switch.
You can use the display poe temperature-protection command to display whether PoE
over-temperature protection is enabled on the switch.
Example
# Disable PoE over-temperature protection on the switch.
<Sysname> system-view
System View: return to User View with Ctrl+Z.
[Sysname] undo poe temperature-protection enable
The temperature protection is disabled.

poe update

Syntax
poe update { refresh | full } filename
View
System view
Parameter
refresh: The refresh update mode is used when the PSE processing software is available. The refresh
update mode is to upgrade the original processing software in the PSE.
full: The full update mode is used when the PSE processing software is damaged. The full update
mode is to delete the original damaged software in the PSE completely and then reload the PoE
processing software.
filename: Update file name, with a length of 1 to 64 characters and with the extension .s19.
Description
Use the poe update command to update the PSE processing software online.
Use the full mode only when the refresh mode fails. In normal cases, use the refresh mode.
When the PSE processing software is damaged (that is, all the PoE commands cannot be
successfully executed), you can use the full mode to update and restore the software.
When the online upgrading procedure is interrupted for some unexpected reason, for example, the
device is restarted due to some errors. If the upgrade in full mode fails after restart, you must
upgrade in full mode after power-off and restart of the device, and then restart the device manually.
In this way, the former PoE configuration is restored.
