Switch Logic Power Good LED

Refer to Appendix A Reference Information for Switch power requirements.

1.Connect the power cable to the front of the chassis.

2.Connect the other end of the power cable to a 3 wire, grounded, AC outlet that delivers power in accordance with the power requirements specified in Appendix A Reference Information. Press the Power Switch to the ON position. Refer to Figure 1-5for its location.

The 3-wire grounded power circuit and the 3-wire power cable provide adequate grounding for the Switch.

Switch Logic Power Good LED

The Switch Logic Power Good LED on the front of the chassis will light when at least one of the two Power Switches has been in the ON position for two or more seconds, and the power supply is supplying DC power within its normal operating limits. Refer to Figure 1-5for the location of the LED.

If the Power Good LED fails to light about two seconds after the Power Switch is pressed to the ON position, ensure that both ends of the appropriate power cord are properly plugged in, the AC power source is turned ON, and that the input fuses for that power input are good.

If you have checked these things and the Power Good LED still is not lit, contact QLogic Customer Support or your authorized maintenance provider. Do not proceed to the next step unless the Power Good LED is lit.

Check the Power-On-Self-Test (POST) Results

When the Power Supply applies DC power to the Switch logic, the logic runs a Power-On-Self-Test (POST) diagnostic. POST tests the condition of firmware, memories, data-paths, and Switch logic and uses the Heartbeat LED to indicate pass or fail conditions. Refer to Section 3 Diagnostics/Troubleshooting for a description of POST.

About three seconds after the Power Good LED comes on, POST will be complete. At this point the Heartbeat LED will start to indicate whether or not there is a POST error. Check the Heartbeat LED. Figure 1-5shows the location of the Heart- beat LED.

If the Heartbeat LED is blinking about once every second, the POST passed and you may go to the next step.

If the Heartbeat LED is not blinking once every second, the POST failed. Note what the Heartbeat LED is indicating (by the flash pattern) and contact QLogic Customer Support or your authorized maintenance provider. Do not proceed to the next step unless the POST passed.
