Installing the I/O Card
The NAM’s I/O card provides the network, DSX, DBM,
modem, DTE and COM port connections. The I/O card
inserts directly behind the NAM that it supports in the
access carrier.
1. Remove the I/O card from the shipping box.
To avoid damaging the card, handle by the top and
bottom edges only.
2. At the rear of the carrier, align the I/O card with the
upper and lower tracks of the slot.
Push gently toward the midplane until it stops and
the card cannot be pushed any further.
