Troubleshooting
Solution
Replace the indicated power supply module. (You can
turn off the audible alarm by inserting an appropriate
tool into the port on the front panel and pressing the
switch.)
Replace the entire power supply housing. (One or both
of the power supply modules may also be bad.)
Solution
Restart your server by pressing the reset button. If the
system is still non-responsive, press and hold in the
power button for 4 seconds to turn the system off. Turn
the system back on, then follow the on-screen
instructions.
Enter the password.
Solution
Enter the password.
Clear the sticking key, then turn off the system, wait for
a few seconds, then turn the system back on.
Make sure the cable is properly connected.
Turn off the system. Turn the keyboard upside down to
drain it, then turn is right-side up to let it dry before using
the keyboard again.
Try a keyboard that you know is working.
