CAUTION: Opening the access panel for an extended period of time when the
server is on interferes with proper airflow and will cause a temperature
violation. It is appropriate to open the server access panel briefly during server
operation to view the internal diagnostic LEDs during problem diagnosis or to
replace a redundant hot-plug power supply or hot-plug fan. If you feel that you
will need to keep the access panel open for an extended period of time, prior to
opening the unit:
1. Close all applications.
2. Bring down the operating system.
3. Press the Power On/Standby switch to place the server in standby mode.
Table C-2
No LED Indicators on the Front Panel Are On
See “Front Panel LEDs” in Appendix D for a complete description of these LEDs.
Possible Reasons Next Steps
1. No AC power. 1. Check power supply installation and look for
missing or bent pins on a power supply.
Try reseating the power supplies.
2. Power supply problem exists. Check
power supply diagnostic LEDs on the front
of the power supply. The power supply
may not be inserted correctly, may have
bent connector pins, or may have failed.
2. Verify that the power switch connector is properly
plugged into the backplane.
3. There is a broken connection between the
system and backplane.
3. Check the power switch cable for bent pins. Try
reconnecting the power switch cable.
Refer to “Power Problems” in the Compaq Servers
Troubleshooting Guide for further options.
