Important Safety Instructions
on page 15.
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.
WARNING:
!
Never install the access carrier on its side. Make sure that it is installed in an
upright position. You MUST ensure that the cards remain in a vertical, upright
position while the unit is operating.

Installing the Access Carrier into a Cabinet/Rack
One 72-inch cabinet can hold up to six access carriers; however, a cabinet does not
need to be fully populated. The minimum vertical distance between access carriers is
1U (1.75 inches, EIA-310-C standard). Follow these rules during installation:
Install access carriers from the bottom of the cabinet and work up. This provides the
following:
—Proper alignment for subsequent access carriers.
—Easier installation since the access carriers can be lowered onto the mounting
screws from above.
—Convenient connection of the interface cables.
—Proper cabinet balance. Bottom-up installation keeps the cabinet from
becoming top heavy.
Install the access carrier into the cabinet/rack before installing any cards in the unit.
Use some type of strain relief to support multiple cables. An RJ48H mass
termination cable is available to attach seven T1 Network interfaces to an M66
block.
The cabinet/rack may or may not have threaded screw holes.
If the

Installing in a Cabinet/Rack with Threaded Screw Holes
Procedure
1. Use a screwdriver to install the screw loosely enough to allow the bracket keyhole to
drop under the screw head during installation. Use the 9th hole as shown on the left
side of the carrier. Use the 12th hole on the right side of the carrier.
2. Place the access carrier against the front rail of the cabinet, allowing the installed
machine screws on each side to pass through the keyholes.
3. Lower the access carrier into place, allowing the keyholes to slide under the screw
heads. Thispositions and supports the access carrier correctly for installation of the
remaining machine screws.
4. Install the remaining machine screws at the top and bottom on each side of the
brackets and tighten them.

Power Supply
The access carrier obtains low-voltage power from the power supply.
The power supply, with its I/O card, is already installed in your access carrier.
You can also order an additional power supply for backup.
The power receptacle is part of the power I/O card.
Installing a Redundant Power Supply
The redundant ac power supply is a separately orderable product. Refer to the
instructions that came with the power supply,
AC Power Supply for 5-Slot Housing and
9000 Series Access Carrier Installation Instructions
, Document No. 9000-A2-GN17, for
installation information.
Power Supply Fan Tray
A power supply fan tray is included with your access carrier beneath the power supply.
You can order a replacement power supply fan tray, if needed. Observe the following
LEDs on the power supply fan tray upon powering up the access carrier.
If this LED is lit . . . Then the power supply fan tray is . . .
Green Operational.
Yellow Not operating at the proper speed.

Alarm Relay Connector
The access carrier provides one independent alarm relay for a system alarm light or
buzzer. This relay uses SPDT (Single Pole Double Throw) contacts (common, normally
open, and normally closed). After making any necessary connections to your alarm
system, plug the connector that you received in the box with the access carrier into the
socket on the power I/O card.
NAM Fan Tray
A fan tray for the NAMs is used so that the ambient temperature remains within the
acceptable range. A replacement fan tray is available as a separately orderable product.
Once the carrier is connected to AC power, the fans in the fan tray begin circulating air
and the green LED lights. If not, check potential reasons in
Troubleshooting
in the
appropriate product manual.
Installing the Baffle
A baffle with self-retaining nuts is provided for heat deflection. Extender brackets are
also provided to convert the baffle for use in a 23-inch rack.
Procedure
1. If installing the baffle in a 23-inch rack, attach the two extender brackets to each
side of the baffle using four of the self-retaining nuts (#12-24) and four of the screws
(#12-24 x 1/2-inch) provided.
2. If the rack does not have threaded screw holes, slip a self-retaining nut onto the first
available hole on each side of the rack beneath the installed carrier. Align the hole
of the nut with the hole in the rail.
