Installation Instructions
Document Number 9000-A2-GN1K-10
September 2000
The 9000 Series Access Carrier with a DC power supply is a metal enclosure that
supports mounting of up to 14 Network Access Modules (NAMs). It has been designed
and approved for use in telephone company central offices only.
It can be mounted in either a 19-inch or 23-inch cabinet or rack. Up to six carriers can
be installed in one standard 72-inch cabinet. All LEDs (light-emitting diodes) on the
NAM(s) are visible from the front of the access carrier. All I/O cables on the I/O card(s)
are accessed from the rear.
Package Checklist
In addition to the access carrier, verify that your package also contains the following:
Power supply (already installed) and power cord
Fan tray for NAMs (already installed)
Baffle for heat deflection, including extender brackets for installation in a 23-inch
rack, and associated screws

!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:
HInstall 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.
HInstall the access carrier into the cabinet/rack before installing any cards in the
unit.
HUse some type of strain relief to support multiple cables.
The cabinet/rack may or may not have threaded screw holes.

Installing in a Cabinet/Rack with Threaded Screw Holes
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. This positions 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.
5
Installing in a Cabinet/Rack without Threaded Screw Holes
1. Slip a Speed Nut into the 3rd, 9th and 16th rail holes on the left side of the carrier,
and into the 3rd, 12th and 16th holes on the right side of the carrier. Align the hole
of the Speed Nuts with the hole in the rails.
2. Place the access carrier against the front rail of the cabinet, allowing the installed
machine screws to pass through the keyholes.

3. Install the remaining machine screws at the top and bottom on both sides of the
brackets, then tighten them.
Power Supply
The DC power supply is designed and approved for –48 VDC power systems. The
access carrier obtains low-voltage power from the power supply.
HThe power supply, with its I/O card, is already installed in your access carrier.
HYou can also order an additional power supply for backup.
HThe power receptacle is part of the power I/O card.
6
Installing a Redundant Power Supply
The redundant DC power supply is a separately orderable product. Refer to the
instructions that came with the power supply,
DC Power Supply for 9000 Series Access
Carrier Installation Instructions
, Document No. 9000-A2-GN1L, for installation
information.
Alarm Relay Connector
The access carrier provides two independent alarm relays for:
HSystem alarm – Connects to the local central office alarm system to report major
and minor alarms, up to 60 VDC and 0.1 amp. Do not exceed these levels when
connecting an alarm to the product.
HPower supply alarm – Consists of an SPDT (Single Pole Double Throw) relay
with terminals that are available for connection to external alarms (common,
normally open, and normally closed). This is used to detect the failure of the power
supply in redundant configurations. The relay is energized when a fault is detected
in either of the redundant power supplies.
After making any necessary connections to your alarm system, plug the connector that
you received in the box with the housing 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
User’s Guide or Supplement.
Installing the Baffle
A baffle with Speed Nuts is provided for heat deflection. Extender brackets are also
provided to convert the baffle for use in a 23-inch rack.
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 Speed 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 Speed Nut onto the first
available hole on each side of the rack beneath the installed carrier. Align the hole
of the Speed Nuts with the hole in the rails.
3. Using four of the screws provided, attach the baffle to the rack immediately below
the carrier, as shown.

Installing Rear Filler Panels
Once I/O card installations are completed, a filler panel must be installed for each
unfilled I/O card slot to ensure compliance with safety requirements.
!WARNING:
Filler panels must be installed on the unused slots to avoid possible injury
from electrical shock.
The access carrier package contains rear filler panels and screws to install unused I/O
card slots. The filler panels provided will cover either four, two, or one empty I/O card
slot(s).
1. Select the proper filler panel size to cover empty slots.
2. At the rear of the carrier, align the filler panel with the upper and lower tracks of the
slot, then screw the panel into place using the screws provided.
NAM Card Installation
A NAM is required for network access and acts as an interface between the network
and the customer premises equipment. NAMs are installed from the front of the access
carrier.
CAUTION:
You must insert the cards in the correct slot so that they mate with their
corresponding I/O cards.
Refer to the Installation Instructions that came with your NAM card(s) for installation
information. Refer to the User’s Guide or Supplement for NAM operation information.

Installing Front Filler Panels
Once card installations are completed, a filler panel must be installed for each unfilled
NAM slot to ensure compliance with safety and FCC requirements.
!WARNING:
You
must
install filler panels on the unused slots to avoid possible injury
from electrical shock.
The access carrier package contains front filler panels for unused NAM slots and
captive screws to install them. Filler panels provided will cover either four, two, or one
empty NAM slot(s).
1. Select the proper filler panel size to cover the empty slots.
2. Latch the front filler panel into place using the upper and lower ejector latches.
