3 LED activity interpretation LED activity interpretation 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. Flashing LEDs 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. Brocade 6505 LEDs The Brocade 6505 has the following LEDs: • One system status LED (upper) on the left side. • One power status LED (lower) on the left side. • Two Ethernet port LEDs (one amber, one green). • One bicolor (green and amber) port status LED for each port on the switch. These LEDs are arrayed above each pair of Fibre Channel ports. • One power supply and fan assembly LED above the AC power switch on each power supply on the non-port side of the switch. LED locations Figure 3 shows the LEd locations on the port side of the Brocade 6505. 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. Refer to Figure 1 for the locations of the FC ports. 18 Brocade 6505 Hardware Reference Manual 53-1002449-01
