Defective
backplane
553-3001-510 Standard 11.00 June 1999
Action
Unseat the CE cards, then reinstall them:
— Make sure all CE cables are securely connected, including the cable
between the IF and FN cards.
— Make sure the ROM card is properly installed on the FN card.
If the system does not recover, continue with this procedure. Try to
sysload after any card is replaced.
Check the inactive CPU by entering:
LD 35
TCPU
— If a disabled card is indicated, check it with the appropriate test or
stat command.
— Try to software enable any disabled card (software disable, hardware
disable, then reenable).
If the system does not recover:
— Unseat all CE cards (including SBE and 3PE cards) on the inactive
CPU; try to sysload by pressing the reload button on the active CMA.
— If a sysload occurs, reinsert the cards one at a time; the system will
fail when the defective card is inserted; replace that card.
If the system does not sysload when all cards are reinstalled on the
inactive CPU:
— Remove the cards from the other CPU and try to sysload.
— Again, if a sysload occurs, reinsert the cards one at a time; replace
the card that causes the failure.
If the system still does not sysload, one at a time, replace the CE cables
until a sysload occurs.
If the system does not recover, go to the next possible cause.
Replace the card cage assembly in the module.
