be different from the subnet used in your network. You might see the following message
if you try to access the switch:
The switch and manager IP address are not in the same subnet.
To resolve this subnet conflict:
1. Disconnect the Ethernet cable between the switch and your network.
2. Shut down power to the switch.
3. Reconnect the Ethernet cable between the switch and your network.
4. Reapply power to the switch.
The switch powers on. The network DHCP server discovers the switch and assigns
it an IP address that is in the correct subnet for the network.
PoE troubleshooting suggestions
Here are some tips for correcting Power over Ethernet (PoE) problems that might occur
on switches that support PoE:
•
Make sure that the PoE Max LED is off. If the PoE Max LED is solid amber, disconnect
one or more PoE devices to prevent PoE oversubscription.
•
Make sure that the Ethernet cables are plugged in correctly. For each powered
device (PD) that is connected to the switch, the associated PoE port LED on the switch
lights solid green. If the associated PoE port LED lights solid amber, a PoE fault
occurred and PoE halted because of one of the conditions listed in the following
table.
Table 6. PoE fault conditions and possible solutions
Possible SolutionPoE Fault Condition
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.
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 15.4W for a PoE connection or
30W for a PoE+ connection.
The PoE current on the port exceeded the classification limit of the PD.
Restart the switch to see if the
condition resolves itself.
The PoE voltage of the port is outside the range that the switch permits.
