1.7.42 CONTBUS-DISABLED
The CONTBUS-DISABLED alarm occurs when an Ethernet card is defective upon insertion into the
chassis or when a card that is already present in the chassis 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
Ethernet slot to the controller card (15310-CL-CTX or CTX2500), 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 IMPROPRMVL alarm during the one-minute 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.
