■ Follow the instructions in “Opening the server case” on page 26 , then make
sure that all cables inside the case are attached securely. Also, make sure
that the colored cable edges are aligned correctly and that the connectors
do not miss any pins.
■ If you have the correct test equipment, make sure that the new battery
has power. Although unlikely, your new battery may be defective.
Beep codes
Whenever a recoverable error occurs during the power-on self-test (POST), the
BIOS displays an error message that describes the problem. The BIOS also sounds
a beep code (one long tone followed by two short tones) during POST if the
video configuration fails (a faulty video controller) or if an expansion card is
not functioning correctly.
A PCI expansion card (for example, a RAID controller) can also issue audible
errors by itself, usually consisting of one long tone followed by a series of short
tones. For more information on the beep codes issued, check the
documentation for that device.
Several POST routines issue a POST terminal error and shut down the system
when they fail. Before shutting down the system, the terminal error handler
sounds a beep code (one long tone and a series of short tones) that identifies
the test point error. If POST completes normally, the BIOS issues one short beep
before passing control to the operating system.
Warning To avoid bodily injury, do not attempt to troubleshoot your
server problem if:
■ The power cord or plug is damaged
■ Liquid has been spilled into your server
■ Your server was dropped
■ The case was damaged
Instead, unplug your server and contact a qualified
computer technician.
