System LED

Table 1-6

System LED

 

 

 

 

Color

 

System Status

 

 

 

Off

 

System is not powered on.

 

 

 

Green

 

System is operating normally.

 

 

 

Blinking Green

 

Switch is running power on self-test (POST).

 

 

Blinking Amber

There is a fault with one of the following:

 

 

Network module (non-traffic-related)

 

 

Power supply

 

 

Fan module

 

 

 

Amber

 

System is receiving power but is not functioning properly.

 

 

 

 

For information on the System LED colors during power-on self-test (POST), see the “Diagnosing Problems” section on page 4-1.

XPS LED

Table 1-7

XPS LED

 

 

 

Color

 

XPS Status

 

 

 

Off

 

XPS cable is not installed.

 

 

Switch is in StackPower mode (Catalyst 3750-X).

 

 

 

Green

 

XPS is connected and ready to provide back-up power.

 

 

 

Blinking green

 

XPS is connected but is unavailable because it is providing power to another device

 

 

(redundancy has been allocated to a neighboring device).

 

 

 

Amber

 

The XPS is in standby mode or in a fault condition. See the XPS-2200

 

 

documentation for information about the standby mode and fault conditions.

 

 

 

Blinking amber

 

The power supply in a switch has failed, and the XPS is providing power to that

 

 

switch (redundancy has been allocated to this device).

 

 

 

Port LEDs and Modes

Each Ethernet port and 10-Gigabit Ethernet module slot has a port LED. These port LEDs, as a group or individually, display information about the switch and about the individual ports. The port mode determines the type of information shown by the port LEDs. Table 1-8lists the mode LEDs and their associated port modes and meanings.

To select or change a mode, press the Mode button until the desired mode is highlighted. When you change port modes, the meanings of the port LED colors also change. Table 1-9explains how to interpret the port LED colors in different port modes.
