There are three possible LED states: no light, a steady light, and a flashing light.
Flashing lights may be slow, fast, or flickering. The LED colors are either green or
amber.
Sometimes, the LEDs flash either of the colors during boot, POST, or other
diagnostic tests. This is normal; it does not indicate a problem unless the LEDs do
not indicate a healthy state after all boot processes and diagnostic tests are
complete.
LED locations
The port side of the switch has the following LEDs (see Figure 11).
v One system status LED (above) on the left side
v
One power LED (below) on the left side
v Two Ethernet Port LEDs (one amber, one green)
v
One bicolor (green/amber) port status LED for each port on the switch. These
LEDs are located above each pair of Fibre Channel ports.
v The serial console port LEDs do not light up at any time, even when a cable is
inserted and the link is active
Figure 11 shows the LEDs on port side of the switch. The port status LEDs for the
FC ports are arranged left and right to correspond to the upper and lower ports
respectively in each pair.
