7.3 Troubleshooting Startup Screen (POST) messages

If the EC system encounters a problem at startup to where it cannot initiate
system software, a BIOS error message indicating the failure will be
displayed.

Some system failures can result in a High Priority alarm displayed.

Message

What it indicates

Troubleshooting Action Required

***NOTE:

RTC failed. xx

This indicates an illegal value in the
CPU's Real Time Clock date or time
registers.

Set the system date and time manually to the
correct values.

***NOTE:

CMOS defaults reloaded.

This is an informational message.

No action needed.

***NOTE:

CMOS battery failed.
Replace soon.

Service is required to replace the CPU
battery.

Replace the battery on the DU CPU board.
Reload software and check out the system.

***NOTE:

Alarm tone detection failed.

Service is required to correct a faulty
connection to the speaker.

Reconnect the speaker if possible. Replace DU
CPU board if speaker connection can not be
corrected.

***NOTE:

ECC failed. xx

The RAM memory ECC circuitry is
faulty.

Replace the DU CPU board.

***NOTE:

System reset. EC xx

This usually indicates a software
(BIOS) failure.

Report this error, along with the machine logs,
to Technical Support.
Reload software. If problem persists, replace
the DU CPU board.

***NOTE:

Critical hardware failure. xx

Some of the DU hardware could not
be initialized.

Replace the DU CPU board.

***NOTE:

OS/App ROM CRC failed.

The software must be reloaded.

Reload software and check out the system.

***NOTE:

System reset.

The software must be reloaded.

Reload Software and check out the system.

Message
