Installing the I/O Card
The NAM’s I/O card provides the COM port, network, DSX and
DTE connections. The I/O card inserts directly behind the NAM
that it supports. Slot numbers are identical (in this case, Slot 01)

Installing the T1 NAM
In both the 2- and the 5-slot housings, the NAM is always installed in Slot 01. The NAM
can be installed in any slot in the access carrier.
!
WARNING:
Do NOT remove any jumpers located on the battery. To do so can cause
non-volatile memory loss. Should a jumper become separated from the
battery, contact your service representative immediately.
CAUTION:
Be sure that you install the NAM in the correct slot so that it mates with its
matching I/O card. Otherwise, you could damage your card.
1. Remove the housing’s bezel, if applicable. See the housing installation instructions
for information.
2. Remove the NAM from the shipping box. Handle only by the top and bottom edges
to avoid damaging the card.
3. At the front of the housing, align the NAM with the upper and lower tracks of
the appropriate slot.
