The UID and the Beacon LED can be turned on by the administrator to indicate that the switch needs attention.
It helps the administrator identify the switch. The beacon can be turned on by either pressing the UID button
on the switch front panel, or by using the CLI. There is a blue beacon on the front and rear panel of the switch.
The blue beacon on the front panel is a button labeled UID, and on the back panel it is a LED labeled BEACON.

is providing power.
Alternating green-amber PoE+ is denied because providing power to the powered
device will exceed the switch power capacity.
Blinking amber PoE+ is off due to a fault or because it has exceeded a
limit set in the switch software.
Caution
Amber PoE+ for the port has been disabled.
Note
PoE+ faults occur when noncompliant cabling
or powered devices are connected to a PoE+
port. Use only standard-compliant cabling to
connect Cisco prestandard IP Phones and
wireless access points or IEEE
802.3af-compliant devices to PoE+ ports. You
must remove from the network any cable or
device that causes a PoE+ fault.
PoE+ is enabled by
default.
