Troubleshooting Switching Modules
Each switching module has one LED labeled STATUS that provides information
about the module and one numbered LED labeled LINK for each port on the
module.
Figure 5-1
shows the Gigabit Ethernet port and status LEDs.
Figure 5-2
shows the 10/100BASE-T port LEDs.
Table 5-1
describes the switching module
LEDs and their expected behavior.
