2.7.65 CONTBUS-DISABLED
The CONTBUS-DISABLED alarm is a function of the enhanced cell bus verification feature. This alarm
occurs when a defective card is installed in the shelf assembly or when a card already installed in the
shelf assembly becomes defective (that is, the card fails the enhanced cell bus verification test). The
alarm persists as long as the defective card remains in the chassis. When the card is removed,
CONTBUS-DISABLED will remain raised for a one-minute wait time. This wait time is designed as a
guard period so that the system can distinguish this outage from a briefer card reset communication
outage.
If no card is reinserted into the original slot during the wait time, the alarm clears. After this time, a
different, nondefective card (not the original card) should be inserted.
When CONTBUS-DISABLED is raised, no message-oriented communication is allowed to or from this
slot to the TCC2/TCC2P (thus avoiding node communication failure).
CONTBUS-DISABLED clears only when the faulty card is removed for one minute. If any card at all is
Caution
reinserted before the one-minute guard period expires, the alarm does not clear.
CONTBUS-DISABLED overrides the
wait period, but afterward IMPROPRMVL can be raised because it is no longer suppressed.
IMPROPRMVL is raised after CONTBUS-DISABLED clears if the card is in the node database. If
CONTBUS-DISABLED has cleared but IMPROPRMVL is still active, inserting a card will clear the
IMPROPRMVL alarm.
