Dual-Purpose Port LEDs

The LEDs on a dual-purpose port show whether an RJ-45 connector is connected to the port, or if an SFP
module is installed in the slot. See the example in
10/100/1000 port through the RJ-45 connector or as an SFP module, but not both at the same time. The
LEDs show how the port is being used (Ethernet or SFP module).
The LED colors have the same meanings as described in

Meaning
PoE is off.
If the powered device is receiving power from an AC power source, the PoE port LED is off
even if the powered device is connected to the switch port.
PoE is on. The port LED is green only when the switch port is providing power.
PoE is denied because providing power to the powered device will exceed the switch power
capacity. The Catalyst 2960-24PC-L, 2960 48PST-L, 2960-48PST-S, and 2960-24PC-S
switches provide up to 370 W of power. The Catalyst 2960-24LT-L and 2960-24LC-S
switches provide up to 124 W of power.
PoE is off due to a fault.
PoE faults are caused when noncompliant cabling or powered devices are
Caution
connected to a PoE port. Only standard-compliant cabling can be used to connect
Cisco prestandard IP Phones or wireless access points or IEEE 802.3af-compliant
devices to PoE ports. You must remove from the network the cable or device that
causes a PoE fault.
PoE for the port has been disabled. By default, PoE is enabled.
