PoE Troubleshooting
Here are some tips for correcting PoE problems that might occur:
•
If the PoE Max LED is solid amber, disconnect one or more PoE devices to
prevent PoE oversubscription.
•
For each powered device (PD) that is connected to the switch, the associated
PoE LED on the switch lights solid green. If the PoE LED lights solid amber, a
PoE fault occurred and PoE halted because of one of the conditions listed in
the following table.
PoE Fault Condition
A PoE-related short circuit occurred on the port.
The PoE power demand of the PD exceeded
the maximum level that the switch permits. The
maximum level is 15.4 for a PoE connection or
30W for a PoE+ connection
The PoE current on the port exceeded the
The PoE voltage of the port is outside the range
that the switch permits
Mount the switch in a rack
We recommend that you use the brackets and screws that came with the switch.
1. Attach the mounting brackets to the side of the switch.
2. Insert the screws through each bracket and into the bracket mounting holes
in the switch.
3. Tighten the screws with a No. 1 Phillips screwdriver to secure each bracket.
4. Align the mounting holes in the brackets with the holes in the rack, and insert
two pan-head screws with nylon washers through each bracket and into the
rack.
5. Tighten the screws with a No. 2 Phillips screwdriver to secure mounting
brackets to the rack.
Possible Solution
The problem is most likely with
the attached PD. Check the
condition of the PD, or restart
the PD by disconnecting and
reconnecting the PD.
Restart the switch to see if the
condition resolves itself.
