Description
The CPU on the processor board generated an exception
interrupt.
The system video adapter is missing, or its memory is
faulty.
Note: This error is not fatal.
The ROM checksum value does not match the value
encoded in the BIOS.
Action
•
Check if the power cord is properly plugged in the power outlet.
If the system is a direct current (dc) version, the power cables
can be reversed; ensure that the polarity of the cables is correct.
• Ensure that the breaker corresponding to the cable is in the ON
position.
• Ensure that the correct type of cable is used, depending on the
type of power supply (ac or dc).
• Check if other equipment plugged in the same power outlet
works.
Note: If the fans are turning, but the system emits no beeps, check if
the monitor is turned on.
Check if the two LEDs on the power supplies (at the back of the
server) are on or red.
• If the LEDs are not on, check the power supply fuse.
• If the LEDs are on and red, one or both power supplies is not
plugged in or plugged in incorrectly, or the connection pins on
the power supplies are bent or missing.
