Port PoE LED is not Solid Green

On those ports that are supplying PoE power to another device, verify that the port PoE LED is solid green. If the LED is not solid green, do the following:

ˆVerify that the connected device is no more than 100 feet from the switch.

ˆIf the port PoE LED is solid amber, then the power required by the connected device is more than the maximum power budget for the port. If this is the case, the connected device may not qualify for connection to the switch.

ˆIf the port PoE LED is blinking amber, then the overall power budget of the switch was exceeded when the powered device was connected. Re-evaluate the overall power requirements of all the powered devices connected to the switch to assure that the overall power budge is not exceeded. This may mean that more than one switch is required to supply the PoE power required by the PoE powered devices on the network.

Note

A 1000Base-T connection may require five to ten seconds to establish a link.
