LED activity interpretation
System activity and status can be determined through the activity of the LEDs on the switch.
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.
Brocade 6520 LEDs
The Brocade 6520 has the following LEDs:
• One system status LED (bicolor: green/amber).
• One power status LED (green).
• Two Ethernet port LEDs (green).
• One port status LED for each port on the switch (bicolor: green/amber). These LEDs are
arrayed above each pair of Fibre Channel ports.
• Two power supply status LEDs per power supply (AC indicator is bicolor: green/amber and DC
indicator is green).
• One fan status LED per fan (bicolor: green/amber).
NOTE
The serial console port LEDs do not light up at any time, even when a cable is inserted and the link
is active.
LED locations
Figure 4 shows the port side of the Brocade 6520. The port status LEDs for the FC ports are
arranged left and right to correspond to the upper and lower ports in each pair. Refer to Figure 1 for
the locations of the FC ports.
