Cisco EtherSwitch Services Modules Chapter 18 Connecting Cisco EtherSwitch Service Modules Table 18-7 Port LEDs on the Cisco StackWise EtherSwitch Service Module (continued) Port Mode LINE PWR Port LED Color Off Green Blinking amber Meaning 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. PoE mode is selected, and the PoE status is shown on the port LEDs. PoE mode is not selected. At least one of the 10/100 or 10/100/1000 ports has been denied power, or at least one of the 10/100 or 10/100/1000 ports has a PoE fault. Table 18-8 Port LED on the Cisco EtherSwitch Service Modules (Excluding the Cisco StackWise EtherSwitch Service Module) Port LED Color Off Green Flashing green Alternating green-amber Amber 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. Note After a port is reconfigured, the port LED can remain amber for up to 30 seconds. Flashing amber 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. 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.
