48.3 PoE Status

A powered device (PD) is a device such as an access point or a switch, that supports PoE (Power over
Ethernet) so that it can receive power from another device through an Ethernet port.
You can also set priorities so that the Switch is able to reserve and allocate power to certain PDs.
Note: The PoE (Power over Ethernet) devices that supply or receive power and their
connected Ethernet cables must all be completely indoors.

DESCRIPTION
Specify how many times the Switch is to resend a ping request before considering the PD

Select Reboot-Alarm to have the Switch turn OFF the power of the connected PD (the

sending an SNMP trap and generating a log message.
When restarting, the PD entry disappears from the Switch's LLDP table and the PD Health
status LED will turn to yellow in the Status > Neighbor screen (see

Select Alarm to have the Switch send an SNMP trap and generate a log message.
Specify the number of seconds the Switch waits before monitoring the PD status again after it
restarts the PD on the port.
Specify how many times the Switch attempts to restart the PD on the port.
The PD Reboot Count will reset
• as soon as a ping is successful,
• or when any modification to the Auto PD Recovery screen is applied,
• or after restarting the Switch.
Specify the number of seconds the Switch waits before supplying power to the connected PD
again after it restarts the PD on the port.
Click Apply to save your changes to the Switch's run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to
save your changes to the non-volatile memory when you are done configuring.
