Power over Ethernet (PoE) Commands
502
ProSafe Managed Switch
no poe timer schedule name
Use this command to detach the schedule from the port.
poe usagethreshold
Use this command to set a threshold (as a percentage) for the total amount of power that can be
delivered by the switch. For example, if the switch can deliver up to a maximum of 300 watts, a
usage threshold of 90% ensures that only 270 watts are used for delivering power to devices.
This ensures that more power is not drawn than the switch can provide.
When the usage threshold is set, all the PDs are brought down and then brought back up. If the
consumed power is less than the threshold power (in the preceding case, 270 watts), then the
devices continue to power up. If the consumed power is 269 watts or less, the next device is
powered up. The moment consumed power exceeds the threshold power (270 watts), no other
devices can power up.
This command allows you to set the usage threshold based on each individual PoE unit or all
PoE units.
no poe usagethreshold
Use this command to set the usage threshold to a default value.
poe traps
Use this command to enable logging of specific PoE-related events, such as a PoE port powering
a device, the threshold being exceeded, and so on.
