Description
* Before replacing the electronics module do the following:
1. Unplug all cables.
2. Plug in the AC power cable and power on the electronics
module.
If the error blink pattern has changed, the problem may not be in
the electronics module. Refer to "Electronics Troubleshooting" on
page 4-51.

Real time clock read failure, POST soft error.
Real-time clock write failure, POST soft error.
Real-time clock re-read failure, POST soft error.
Real-time clock does not tick, POST soft error.
Memory test, less than 128 MB of RAM detected. This is the
minimum RAM required. Add more RAM. Reseat the RAM
SODIMM(s), then replace the RAM SODIMM(s), POST hard error.
