Cisco EtherSwitch Services Modules Chapter 18 Connecting Cisco EtherSwitch Service Modules Port Numbering The Ethernet ports are numbered right to left, top to bottom. The port numbering scheme to configure the ports on the Cisco EtherSwitch service module includes the port type (such as fa or fastethernet for Fast Ethernet, or gi or gigabitethernet for Gigabit Ethernet), the stack member number (range is 1 to 9), the module slot number (always 0), and the switch port number. For example, to configure the Fast Ethernet port 3 on stack member 1, the interface configuration command would be: switch (config)# interface fa1/0/3 Cisco EtherSwitch Service Module LEDs Cisco EtherSwitch service module LEDs provide green, amber, and off states for system and port status. The following sections describe LEDs on the service modules: • EN LED • System LED • Master LED • Port Mode LEDs • Port LEDs • Port LEDs in Stack Mode Note LEDs for System, Master, Port Mode, and PoE are available on the 24-port Cisco StackWise EtherSwitch service module only. Port LEDs on nonstacking Cisco EtherSwitch service modules only show link status. EN LED All Cisco EtherSwitch service modules have an enable (EN) LED. This LED indicates that the module has passed its self-test and is available to the router. (See Figure 18-5.) Table 18-3 lists the EN LED colors and their meanings.
