Power Supply Troubleshooting
Table 3-1
and
Table 3-2
are troubleshooting matrixes for finding AC source power
and Power Supply problems. They use indications such as LEDs and fan rotation to
find problems. Use
Table 3-2
for chassis that contain one Power Supply. Use
Table
3-1
for chassis that contain two Power Supplies.
If the appropriate table does not lead you to the problem or if you need a new
Power Supply, notify QLogic Customer Support or your authorized maintenance
provider. Refer to
Appendix B QLogic Customer Support
for information about
how to contact QLogic Customer Support.
