ˆ 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.
ˆ 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.
ˆ 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.
