FHW0003 12

[westcoaster]

opt 11c
version 2111
release 22
issue 8 D

ERR4286 12 (message count on the loop exceeds the threshold value)
FHW0003 12 (loop n has been detected as faulty by loip function ini000 0006 has been averted)

After several warnings with the ERR message (period of three hours or so), The FHW message pops up on the screen and the cards in slots 13, 14, 15 and 16 go into MBSY and eventually disable.
After the FHW0003 the terminal shows "NPR0000" and "NPR0003 PBXT DONE" it keeps repeating, and repeating, and... with a sprinkling of NPR300 thrown in for good measure.

there are only two cabnets on this system, I have replaced the fibre cord and the fibre receiver card (no change so the old cord and receiver went back in). today I threw in a fibre daughter board. I am still getting err4286 messages. I don't think throwing hardware at it is the answer as we have started to upgrade this switch to succession. So far the only thing done, is to load the callpilot migration utility on to the MM (when all my problems started...) Unfortunatly the MM powered up and down several times before it would boot from the tape (technician error (me))
does the opt 11c have loops? I couldn't help notice how this fault has played out...
card slots: (1, 2, 3, 4) (5, 6, 7, 8) (9, 10, 11, 12) (13, 14, 15, 16) (17, 18, 19, 20)
The cards in the expansion cabnet that occupy slots 11, 12, and 17 work just fine. All the cards in the main cabnet work just fine. just that fourth group of four goes faulty.

any and all sugestions where to go from here would be welcome. I had started another thread a short time ago

with the new info I thought it would be more useful to start a new thread...

The option 11C uses superloops to control card slots.

SUPL Cards
0 1-4
4 5-8
8 9-12
12 13-16
16 17-20

32 21-24
36 25-28
40 29-32
44 33-36
48 37-40

64 41-44
68 45-48
72 49-50

P096 61-64
P100 65-68
P104 69-72
P108 73-76
P112 77-80

If superloop 12 goes bad, then it would affect cards 13-16, as you stated above. I'm not sure what would cause such a problem, but you could try relocating the cards to a different superloop (group of 4 card slots) in order to see if one of your line cards is bad? Anyone else with ideas?
