Front Panel LEDs
Refer to Figure 1-5. LEDs visible through lenses in the front of the chassis indicate
chassis and port status. During a Reset operation (for about two seconds at the
beginning of power-up) all LEDs are forced ON. The following definitions are
valid following the Power-On-Self-Test (POST) when the POST finds no errors.
Refer to Section 3 Diagnostics/Troubleshooting for information about how the
LEDs act if the POST finds an error or if the control code (located in Flash
memory) hangs up.
Heartbeat LED (Yellow)
The Heartbeat LED indicates the status of the internal Switch processor and the
results of Power-On-Self-Tests (POSTs) run at power-up.
Following a normal power-up the Heartbeat LED blinks about once per second to
indicate that the Switch passed the POSTs and the internal Switch processor is
running.
Refer to Section 3 Diagnostics/Troubleshooting for more information about Heart-
beat LED error codes.
Switch Logic Power Good LED (Green)
This LED is ON when the Power Supply is delivering power within normal limits
to the Switch logic (the Power Switch must be ON).
Fan Fail LED (RED)
This LED is normally OFF. It comes ON only when the speed of a Fan drops below
operational level. Refer to Figure 1-5 for the location of the LED. Contact QLogic
Customer Support if a Fan fails.
Over Temperature LED (Red)
This LED is normally OFF. The over temperature LED illuminates to indicate that
the air temperature inside the switch has exceeded a certain limit. If this LED
illuminates, inspect the following:
• Ambient air temperature: maximum 40°C (104°F)
• Proper clearance: 163mm (6.5”) front, left side, and back
• Fan operation
• Power supply operation
If the over temperature LED remains illuminated, contact your authorized mainte-
nance provider (refer to Appendix B).
