Power Supply Troubleshooting

Power Supply Troubleshooting

Table 3-1and Table 3-2are 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 3-2for chassis that contain one Power Supply. Use Table 3-1for 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.
