Interpreting LEDs
System activity and status can be determined through the activity of the LEDs on
the switch. There are three possible LED states: no light, a steady light, and a
flashing light. The lights are green or a combination of green and amber.
Note: The LEDs may flash during boot, POST, or other diagnostic tests. This is
normal and does not indicate a problem.
LEDs on the port side of the switch
The port side of the switch has the following LEDs (see Figure 15).
v One system status LED (above) on the left side
v
One system power LED (below) on the left side
v One Ethernet link LED at the Ethernet management port
v
One Ethernet activity LED at the Ethernet management port
v One link LED at each GE port
v
One activity LED at each GE port
v One port status LED for each Fibre Channel port
Figure 15 shows the LEDs on port side of the switch.
