Safety Instructions
Please read the EMI warning and Important Safety Instructions that come with this unit.
!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. See the
FrameSaver 9620 Technical Reference (Document No. 9621-A2-GH30) for FTP
instructions.
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. Reinstall the DBM onto the replacement NAM.
Refer to the
ISDN BRI Dial Backup Module (DBM) Installation Instructions to uninstall
and reinstall 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
reinstalling the cables.

Recommended Order for Installing a NAM into an Access
Carrier
1. Install the I/O card.
2. Connect all cables into the I/O card.
3. Install the NAM.
4. Go to the
9000 Series Access Carrier Installation Instructions for power-up
verification procedures.
Installing the I/O Card into the Access Carrier
The NAM’s I/O card provides the COM port, network, 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.

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 NAM from the shipping box. Handle only by the top and bottom edges
to avoid damaging the card.
2. At the front of the carrier, align the NAM with the upper and lower tracks of
the appropriate slot.

Removing/Replacing a Card in the Access Carrier
Card removal procedures differ, depending on whether you are removing the card from
the front or rear of the carrier.
Removing/Replacing the NAM

2. Press open the ejector latches to disengage the card.
3. Supporting the card by its edges, pull straight out until the card clears the carrier.
4. Align the replacement card with the upper and lower tracks of the slot. Slide
forward until the NAM seats. Be careful not to force or bend any pins.
5. Close both the upper and lower ejector latches on the carrier to lock in place, then
tighten the captive screws.
Removing/Replacing the I/O Card
1. Remove the NAM from the carrier (see Removing/Replacing the NAM ).
2. Remove the network, DTE and COM port cables from the I/O card (if applicable).
3. Using a screwdriver, loosen the upper and lower screws fastening the card to the
carrier’s frame.
4. Gently pull the I/O card away from the midplane until it clears the carrier.
5. Reinstall the NAM.
6. Align the replacement 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.
7. Alternately tighten each captive screw until the screws are all the way in.
8. Reattach the cables as appropriate.

Troubleshooting
Symptom Possible Cause Solutions
No power, or none of the
system LEDs are lit. The power cord is not
securely plugged into the
wall receptacle, or into the
rear panel connector.
Check that the power cord
is securely attached at both
ends.
The wall receptacle has no
power. 1. Check the wall
receptacle power by
plugging in some
equipment that is known
to be working.
2. Check the circuit
breaker.
LED is burned out. Run the Lamp Test. If the
LED in question does not
flash with the other LEDs,
then contact your service
representative.
Power supply is defective. Contact your sales or
service representative.
Power-Up Self-Test fails.
Only Alarm LED is on
after power-up.
The access unit has
detected an internal
hardware failure.
