SANbox-16HA Fibre Channel Switch
Installer’s/User’s Manual 59005-03 Rev. A Installation 2-7
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 1-5 for 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 1-5 for 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 1-5 shows 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.
