Descriptions and Error Codes
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.
Read Error Register Test
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:
