Investigate tests in the order shown in. By clearing error codes associated with the first test, you 
may clear errors generated from other tests in the sequence.

The Read Error Register test queries three registers including the:

●

Optical line receiver’s CRC error register

CRC errors indicate problems with the optical interface between the active and standby 
servers.

●

SDRAM’s single-bit error register

Although the Duplication Memory board can “self heal” single-bit errors in the SDRAM’s 
error register, chronic problems can indicate a more serious problem.

●

SDRAM’s multiple-bit error register

An SDRAM multiple-bit error condition indicates a problem in the Duplication Memory 
board’s memory, and cannot be recovered.

The following errors can be detected:

1. D = Destructive; ND = Nondestructive
