POST message Description
20x A failure occurred during the memory test. This error can be
caused by:
Ÿ
Incorrectly installed memory
Ÿ
A failing memory module
Ÿ
A system-board failure
Action:
1. If you just installed memory, verify that the new memory is
correct for your system, and that the memory modules are
installed properly. If the memory is not installed correctly,
reseat the memory modules. (See “Working with memory
modules” on page 96.) Verify that the memory modules are
configured correctly. (See Chapter 3, “Configuring your
server” on page 33.)
2. Run the diagnostic programs to verify the problem. (See
“Running the diagnostic test programs” on page 164 for
information on running the diagnostic programs that come
with your server.)
If the problem cannot be isolated and corrected, have the system
serviced.
301
303 An error occurred during the keyboard and keyboard controller
test. These error messages also might be accompanied by
continuous beeping.
Action:
Ensure that:
1. Nothing is resting on the keyboard and pressing a key.
2. No key is stuck.
3. The keyboard cable is securely connected to the keyboard
connector on the server. (See “Input/output connectors” on
page 11 for the location of the keyboard connector.)
Note: If you have just connected a new mouse or other pointing
device, turn off the server and disconnect that device.
Wait at least 5 seconds; then, turn on the server. If the
error message goes away, replace the device. If the error
message remains, have the keyboard, cable, and system
serviced.
