A major CB 0 failure alarm occurs in the event of a bad CB (unknown or mismatched CBs
do not trigger this alarm in Junos Release OS 12.3R9 and later). Following GRES or
recovery, if the hardware issue persists, the traffic moves to the good CB and continues.
If the alarm was triggered by something transient like a power zone budget on GRES,
bringing the CB back online can clear the alarm. Otherwise, replace the bad CB. Note
that fabric link speed is not impacted by an offline SCB. The alarm migh be raised on
CB0, CB1, and CB2.
