other cards, there will be a conflict for resources. The conflict results in any circuits previously
switched to the spare low-speed card (and still present there) to be switched back to their home low-
speed cards. If the home low-speed cards are not able to maintain the circuits, the circuits will be
dropped.
MSO Conflicts with Spare Card
If you remove more than one MSO Electronics card section from a Wide Bank, there will not
be enough spares to maintain traffic. This conflict will cause all low-speed circuits handled by
the removed electronic sections to be dropped. To resolve the conflict, re-insert all the MSO
Electronics card sections, then remove and replace only one card at a time, starting with the card
containing the failed low-speed circuits. Removing the relay sections of the MSO cards will
also resolve the conflict but will not restore dropped circuits.
