1. GENERAL

This practice provides installation and maintenance

procedures for the ADTRAN 23-inch T400 Shelf,

illustrated in Figure 1.

Revision History

Issue 5 clarifies shelf backplane fuse requirements and

updates text format.

Features

The T400 shelf, P/N 1150092L1, supports the

following features and functions:

•Accommodates up to 14 industry standard

T400/T200 circuit packs.

•Meets applicable sections of GR-1089-CORE

and GR-63-CORE for NEBS Level 3

Compliance.

•Provides four 25-pair amphenol connectors.

•Locking front cover.

•Various mounting positions for standard rack

configurations.

•Loss of power alarm relay.

•Front panel electrostatic discharge (ESD)

grounding jack.

General Description

The T400 Shelf is designed to deploy T200/T400

circuit packs. The shelf supports 2-wire, 4-wire, or

two to 4-wire circuit pack form factors for both central

offices and customer premises.

Equipped with mounting flanges, the T400 shelf

installs in a standard 23-inch central office

communications bay. The shelf measures 21 inches

wide, 11 inches deep, and 7 inches high, occupying

four vertical rack units. Two sets of holes on the

mounting flanges allow for positioning the shelf in

either of two standard bay mounting configurations.

The shelf backplane printed circuit board (PCB)

accommodates card edge connectors plus the

interconnects for signals, power, ground, and loss of

power alarm (Figure 2). The backplane of the T400

Shelf contains the following:

•Fourteen 56-pin card edge connectors, one for

each individual circuit pack.

•Four 50-pin male amphenol connectors for

input/output signals.

•One loss-of-power relay.

•One five-terminal barrier strip for power,

ground, frame ground, and two Loss-of-Power

Alarm contacts.

2. INSTALLATION

After unpacking the unit inspect it for damage. If

damage is noted, file a claim with the carrier, then

contact ADTRAN. See Warranty and Customer

Service.

After unpacking the shelf, verify the zip-lock bag

contains the following items:

•Four cable tie-wrap mounts.

•Five cable tie-wraps.

•Five #12-24 mounting screws.

•One card and card pouch.

•One key for lockable front cover.

Before installing the T400 Shelf into a bay, remove

any plug-in cards that were shipped with the shelf. To

remove the cards, grasp the faceplate handle and pull.

Temporarily store these units in an area protected

from static electricity.

Mounting

The T400 Shelf is designed to mount directly into a

standard 23-inch wide flange type communications

bay. The T400 Shelf is factory configured to mount 4

inches from the front of the bay. Holes are also

provided for mounting the shelf 5 inches from the

front of the bay. The flanges are easily repositioned

for the applicable mounting arrangement.

Instructions for mounting and electrically connecting

the T400 Shelf in the bay are as follows:

1. Determine the chassis location in the bay.

2. Align the flange mounting holes on each side of

the shelf with the bay mounting holes and

secure with supplied fasteners.

3. Remove the rear cover by disengaging the two

Phillips-head screws.

NOTE

Customer supplied ring-lug wire terminals are

recoáGended for TS1 connections.

4. Insert wires through the cable side entry

grommet before attaching ring-lug terminals.

5. Connect a fused -48 Vdc supply and return, that

is electrically isolated from an AC source, to

-48 V and GND on TS1 (see Figure 3). Fuse

rating depends on the type of circuit cards

deployed. Maximum current for the shelf PCB

is 15 A.

NOTE

Although rated at 15 A, the shelf PCB can be

fused at 5 A if all shelf units are ADTRAN.

6. Connect frame ground to TS1 FRAME (see

Figure 3). Because the 48 V return (TS1 GND)

is isolated in the shelf, connect it externally to a

central ground.

7. Connect power alarm contacts to TS1-A and B

(see Figure 4).

8. Provide some slack to ensure that wiring and

terminals are not under strain then tie down the

TS1 wire bundle using the cable tie mount and

wrap provided.

WARNING

Do not dislodge or damage the fiber sheet

insulators on the inside of the cover.

CAUTION

To meet accessibility requirements of

GR-1089-CORE Electrical Safety Criteria, the

rear cover must be installed when span powering

voltages meeting Class A2, A3, AB, B, or C are

present. The front access cover must be installed

when circuit pack design does not prevent

inadvertent contact with non-Class A1 voltage

limits.

9. Replace the shelf rear cover and reinstall the

screws.

10. Determine the routing direction of the

amphenol connector and cable. Insert the cable

tie-wrap mounts into the appropriate holes of

the rear cover, based on the routing direction.

Cable tie-wrap mounts should be located on the

cable side of the amphenol connector.

11. Attach the applicable 50-pin female amphenol

cables to P1, P2, P3, and P4 of the shelf

backplane. See Figure 2. Use the cable tie-wrap

mounts and tie-wraps provided to secure the

cabling.

Power, Ground, & Data Connections

The 14 slot backplane connectors are all identical.

Refer to Table 1 for pinout connections for power,

ground, and tip and ring connections.

Table 2. Interface Wiring for P1 Through P4

Telco Connectors

Four 50-pin amphenol connectors (P1 through P4) are

provided for the interconnect wiring of the 14 channel

positions. The connector is usually terminated with a

punch-down block for customer premises wiring or

connected directly to a cross-connect or main

distribution frame. Table 2 describes and Figure 5

details the pinout of each connector.

Loss-of-Power Alarm

The T400 Shelf provides an alarm contact which is

open during normal conditions. During a loss of

power the alarm contact will close. The dry contact

closures are rated for 125 Vac at 10 mA and are

designed for connection to a central office alarm

system, such as Dantel.

ESD Grounding Jack

The installer should use the ESD grounding jack

provided at the front of the shelf as a known ground to

prevent ESD during plug-in unit installation.
