Port LEDs in Stack Mode
The port LEDs in Stack mode show the stack member number of the Cisco StackWise EtherSwitch
service modules in the stack. Up to nine service modules or switches can be members of a stack.
Therefore, only the first nine port LEDs are used in Stack mode to reflect stack membership.
For example, you have a stack of three EtherSwitch service modules. Their stack member numbers are
3, 4, and 8. If you select the Stack mode on member number 8, then port 8x flashes green. Ports 3x and
4x display continuous green, showing you have two other stack members whose member numbers 3 and
4. All other LEDs are off since there are no other members in the stack. (See

Port LED
Color Meaning
Off PoE mode is not selected. None of the 10/100 or 10/100/1000 ports
have been denied power or are in a fault condition.
Green PoE mode is selected, and the PoE status is shown on the port LEDs.
Blinking PoE mode is not selected. At least one of the 10/100 or 10/100/1000
amber ports has been denied power, or at least one of the 10/100 or
10/100/1000 ports has a PoE fault.
EtherSwitch Service Module)
Description
No link, or the port was administratively shut down.
On PoE ports, no inline powered device (PD) detected, or the port is not
connected.
A link is present. The port or system is functioning normally.
On PoE ports, the Cisco EtherSwitch service module is providing power to a PD.
Activity is occurring. The port is transmitting or receiving data. Module POST is
in progress.
Link fault.
On PoE ports, the Cisco EtherSwitch service module is denying power to a PD,
or is experiencing a power delivery fault.
The port is blocked by the Spanning-Tree Protocol (STP) and is not forwarding
data.
After a port is reconfigured, the port LED can remain amber for up to
Note
30 seconds.
On a PoE port, indicates that the port is denied power and that the port is
administratively disabled.
The system is receiving power but is not functioning properly.
The port is blocked by STP and is transmitting or receiving packets.
On a PoE port, indicates an inline power delivery fault.
