Safety guidelines
While troubleshooting your server, follow these safety guidelines:
■ Never remove the top panel while your server is turned on and while the
modem cable and the power cords are connected.
■ Do not attempt to open the monitor. To do so is extremely dangerous.
Even if the power is disconnected, energy stored in the monitor
components can be dangerous. Also, opening the monitor voids its
warranty.
■ Make sure that you are grounded correctly before opening the server. For
more information about preventing damage from static electricity, see
“Preventing static electricity discharge” on page 30 .
■ After you complete any maintenance task where you have to open the
server case, make sure that you close the case and reconnect all cables
before you restart your server.
Warning
To avoid bodily injury, do not attempt to
troubleshoot your server problem if:
- The power cords or plugs are 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.
Error messages
These messages often indicate procedural errors such as typing an incorrect
keystroke or trying to save a file to a write-protected diskette. Some messages,
however, may indicate a problem that requires further troubleshooting.
Memory messages
Gate20 Error
The BIOS is unable to correctly control the system board’s Gate A20 function,
which controls access of memory over 1 MB. This may indicate a problem with
the system board.
Multi-Bit ECC Error
This message will only occur on systems using ECC enabled memory modules.
ECC memory has the ability to correct single-bit errors that may occur from
faulty memory modules.
A multiple-bit corruption of memory has occurred and the ECC memory
algorithm cannot correct it. This may indicate a defective memory module.
Boot messages
Boot Failure ...
This is a generic message indicating the BIOS could not boot from a particular
device. This message is usually followed by other information concerning the
device.
