Chapter 3: Troubleshooting

 If 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.

 If 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.

 If the PoE LED is off, then do the following:

– Verify that the twisted pair cable is securely connected

to the port on the switch and to the port on the

connected device; and

– Verify that the connected device conforms to IEEE

802.1af

Note

A 1000Base-T connection may require five to ten seconds to

establish a link.
