ROUBLESHOOTING
At initial power-on or during a reset, Power and Self Test LEDs fail to
light.
Meaning: There is no power to the server.
Action: Power off the server by pressing the O side of the power
switch, then do the following:
1 Verify that the power cord is plugged securely into the power supply
module.
2 Verify that the power cord is connected to an outlet.
3 Ensure that power is available at the outlet you are using.
4 Inspect the server’s fuse and replace it, if necessary. For instructions,
refer to “Replacing the Fuse” on page 5-2.
5 Try replacing the power cord.
If the Power and Self Test LEDs still fail to light, contact 3Com or your
network supplier.
During self-tests, the Self Test LED remains on for longer than about a
minute or the console displays an error message.
Meaning: The server has failed a self-test.
Action: The server may not always be able to report a failure on the
console (for example, CPU failure). If a lighted Self Test
LED is the only symptom, contact 3Com or your network
supplier.
If an error message appears on the console, refer to
Appendix B, “Startup Messages,” for information. Report
the failure and console messages to 3Com or your network
supplier.
The Boot State LED remains on or goes on and off cyclically.
Meaning: The boot source is not present or not responding.
Action: Take the following action:
1 Check the console for messages.
Follow the instructions in the message (for example, insert the diskette
in the disk drive).
