LEDs

You can use the switch LEDs to monitor switch module activity and performance. Graphical representations of the LEDs described in these sections are visible in the device manager.

•Stack LED, page 1-5

•Stack Master LED, page 1-6

•Stack Member LED, page 1-6

•UID and Health LEDs, page 1-6

•RJ-45 Uplink Port LEDs, page 1-6

Note The System LED (SYST), stack LED (STCK), Stack Master LED (MSTR), and Stack Member LED (MMBR) are shown as item 4 in Figure 1-1 on page 1-2.

System LED

The System LED (SYST) shows whether the system is receiving power and is functioning properly. Table 1-2lists the LED colors and their meanings.

Table 1-2	System LED

Color		System Status

Off		System is not powered on.

Blinking green		POST is in progress.

Solid green		System is operating normally.

Amber		System is receiving power but is not functioning properly.

Stack LED

To see the status of the StackWise Plus ports, press the Mode button. The Stack LED (STCK) is green when the StackWise Plus ports are up and amber when the ports are down. The bottom two 10-Gigabit Ethernet module slot LEDs show the status for StackWise Plus ports 1 and 2, respectively (see item 11 in Figure 1-1 on page 1-2).

When in stack mode, if both 10-Gigabit Ethernet uplink port LEDs are green, the stack is operating at full bandwidth. If one or both of the 10-Gigabit uplink LEDs are not green, the stack is not operating at full bandwidth.

See the “LED Behavior in Stack Mode” section on page 1-8for more information.
