Alarm Log Entries
Notes:
a. Event ID #2 Test failed — Error counter query for single-bit EDC (bad error register) on
the SDRAM is pegging. If the test detects 20 consecutive failures, the following Warning
alarm is logged:
#1,ACT,[DAJ1|DAL1],A,2,WRN,Single-bit EDC test (bad SB err count)
b. Event ID #3 SDRAM has multiple bit errors — The [DAJ1|DAL1] board can also
generate this event as an in-line error.
If this test detects a failure, the media server’s state of health is lowered to its most
critical level, and the following Major alarm is logged:
#1,ACT,[DAJ1|DAL1],A,3,MAJ, SDRAM multibit errors
c. Event ID #4 Looparound test failed — Either a mismatched address or a mismatched bit
pattern could have caused a failure.
If this test detects 3 failures, the following Minor alarm is logged:
#1,ACT,[DAJ1|DAL1],A,4,MIN,Local Looparound test failure
d. Event ID #5 Optical Line Receiver experiencing CRC errors — If this test detects 3
failures, the following Minor alarm is logged:
#1,ACT,[DAJ1|DAL1],A,5,MIN,Link Receiver CRC errors
e. Event ID #6 Inability to open a communications link with the Duplication Memory board.
The board is out of service if this failure occurs once, and a Major alarm is logged:
#1,ACT,[DAJ1|DAL1],A,6,MAJ,Failed to open [DAJ1|DAL1] card
