Safety Instructions
Please read the EMI warning and Important Safety Instructions that come with this
NAM.
!HANDLING PRECAUTIONS FOR STATIC-SENSITIVE DEVICES
This product is designed to protect sensitive components from
damage due to electrostatic discharge (ESD) during normal
operation. When performing installation procedures,
however, take proper static control precautions to
prevent damage to equipment. If you are not sure
of the proper static control precautions, contact
your nearest sales or service representative.
Removing a NAM from a 1-Slot Housing
Before replacing a NAM, locate or record the access unit’s configuration options, or
transfer the configuration using the FTP (file transfer protocol) feature. This is useful
when setting up the replacement NAM, verifying operation, or troubleshooting.
1. Disconnect the power cord/transformer, first from the ac outlet, then from the rear
of the access unit.
2. Disconnect the other cables.
3. Open the 1-slot housing using a small flat-head screwdriver. Gently pry open the
housing at each of the four connecting tab points. However, if the screwdriver is
too big or you do not open carefully, you could cause damage to the housing.

6. Work the NAM away from the I/O card (not the backplane,
since the backplane might bend) by very carefully and
gently pulling and rocking the NAM connectors
away from the I/O card connectors. Work
first from one side, then the other,
until the NAM is separated from the
I/O card. Set the NAM aside.
If an ISDN BRI DBM is Installed
1. Remove the DBM from the NAM being replaced.
2. Re-install the DBM onto the replacement NAM.
Refer to the
ISDN BRI Dial Backup Module (DBM) Installation Instructions
to de-install
and re-install the DBM.

Installing a NAM in a 1-Slot Housing
1. Remove the NAM from its shipping box.
2. Carefully align the NAM connectors with the
integrated I/O card/backplane (rear panel)
connectors. (See Step 3 of
Removing a
NAM from a 1-Slot Housing
on Page 2
if you need to open the housing first.)
3. Gently, but firmly press the connectors
together until they are fully seated.
Be careful not to force or bend
any pins.
4. Place the NAM and integrated I/O card/backplane
into the 1-slot housing’s base. Make sure the
backplane rests inside the guides on the
base at the rear of the access unit.
5. Place the cover over the base, aligning the four connecting tabs. Make sure the
backplane rests inside the guides on the cover at the rear of the access unit.
6. Press the cover and base together until all four connecting tabs snap into place.
7. Reconnect the power cord/transformer, verifying that the faceplate’s OK LED lights
once the self-test is passed.
Refer to the
1-Slot Assembled Access Unit Installation Instructions
before
re-installing the cables.

Installing the I/O Card into the Access Carrier
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.
1. Remove the I/O card from the shipping box. Handle only
by the top and bottom edges to avoid damaging the card.
2. At the rear of the carrier, align the I/O card with the
upper and lower tracks of the slot. Push gently towards
the midplane until it stops and you cannot push the card
any further.

block. The T1 mass termination cable is a 5-foot RJ48H cable consisting of a 50-pin
plug-to-seven RJ48C plugs. See the RJ48H Connector for T1 Mass Termination Cable
table on page 20 for pin assignments.
1. Insert up to seven of the RJ48C plugs on the RJ48H network cable into the NET
interface(s).
2. Insert the 50-pin plug end of the cable into the M66 block.
