POST Messages POST message 162 Description 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. Microprocessor update code has not been installed or cannot be found. The Erasing Lost or Forgotten Passwords procedure was performed. This procedure also erases configuration data. An invalid checksum is detected in CMOS memory (nonvolatile RAM). Action: 1. Verify that all external devices are turned on. You must turn on external devices before turning on the server. 2. Verify that all devices are properly installed and securely connected. 3. If you added, removed, or changed the location of a device, or if you erased passwords, you must save the new configuration in the Configuration/Setup Utility program. See "Using the Configuration/Setup Utility program" on page 39 for further information and instructions on saving the configuration. 4. If you changed the microprocessor, you must use the Configuration/Setup Utility program to update the settings. You must also update the server configuration. See "Updating the server configuration" on page 153 for instructions. 5. If you did not add, remove, or change the location of a device, a device is probably failing. Running the diagnostic tests might isolate the failing device, but you must have the system serviced. (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. Chapter 5. Solving problems 171
