POST message
162 A change in device configuration occurred. This error occurs under one or more of the following
conditions:
• A new device has been installed.
• A device has been moved to a different location or cable connection.
• A device has been removed or disconnected from a cable.
• A device is failing and is no longer recognized by the server as being installed.
• An external device is not turned on.
• An invalid checksum is detected in the battery-backed memory.
Action:
If you did not add, remove, or change the location of a device, a device is probably failing.
Running the Diagnostic program might isolate the failing device.
If you cannot isolate and correct the problem, call for service.
163 The time of day has not been set.
Action:
You can use the server until the system is serviced, but any application programs that use the
date and time will be affected.
164 A change in the memory configuration occurred. This message might appear after you add or
remove memory.
Note: The server can be used with decreased memory capacity.
Action:
If the problem persists, call for service.
175 A vital product data (VPD) error occurred.
Action:
176 A security hardware error occurred.

Table 16. POST error messages
Verify that all external devices are turned on. You must turn on external devices
before turning on the server.
Set the correct date and time. If the date and time are set correctly and saved, but the
163 error message reappears, call for service.
1. If POST error message 289 also occurred, follow the instructions for that error
message first.
2. If you just installed or removed memory, run the Configuration/Setup Utility
program; then, exit, saving the new configuration settings.
If the message appears again, shutdown the server, reseat the memory modules,
and restart the server.
3. If the problem persists, check to see if the system has isolated the problem to a
memory module:
• If the System Error light on the operator information panel is on, check to see
if the MEM LED on the diagnostic LED panel is on. If it is on, check the
DIMM Error LEDs next to the memory sockets. If a DIMM Error LED is on,
run the diagnostic program for the memory.
— If the tests fail, replace the DIMM. If the problem persists after you
replace the DIMM, call for service.
— If the memory tests do not fail, call for service.
• If no error LED is on, the error logs in the Configuration/Setup Utility program
might provide additional information on the memory error.
Call for service.
Check for indications that someone has tampered with the server. If no one has
tampered with the server, call for service.
