Warning
Cards must be inserted in the correct slot positions. This is particularly true with back cards. If
service module back cards are inserted into slots intended only for ASC and/or BNM back cards
(slots 1, 2, 3, and 4), damage to the card and backplane can result.
If you accidentally attempt to insert a service module back card into slots 1, 2, 3, or 4 and have
difficulty in operating the shelf, examine the backplane pins and the backcard connector to see
if they have been bent or damaged.
