1. GENERAL
1.1 This section provides installation and
maintenance information for the ADTRAN Type 400
(T400)SingleMount Housing. Figure1isanillustration
of the unit. The part number and basic features for the
unit are provided in Table A.
The T400 Housing is used to house a standard
T400 circuit pack, and is capable of performing loop
termination.
1.2 Future changes to this practice will be listed in
this paragraph.
1.3 The T400 Housing is designed to accept any
standard Type 400 plug-in card. For non-loop powered
units,the T400 Housing can providepowertothe circuit
card through an external power supply. The ADTRAN
1353.DSK48V02 power supply can be used to provide
-48 VDC from standard 120 VAC to power these cards.

DESCRIPTION
1.4 The ADTRAN T400 Housing, part number
1242034L2, is a Type 400 metal chassis that can be
either table or wall-mounted. It houses a single T400
circuit card.
2. PHYSICAL DESCRIPTION
2.1 Figure 1 shows the ADTRAN T400 Housing
with the cover on. Connections are made available by
unscrewing the lock screw and lifting the hinged cover.
2.2 Inside the housing is a terminal barrier strip
(Figure2)forconnectingtothenetwork,totheCPE,and
toanexternalpowersource,ifoneis used. Agrounding
lug is provided for frame ground connections.

2.3 The rear panel of the T400 Housing contains a
slotforeitheranRJ-48Cjack(factoryinstalled)oranRJ-
48X jack (shipped loose) for CPE connections, and a
portal for network and power connections (see Figure
3).
2.4 The T400 Housing is 2 inches high by 6.00
inches wide by 9.75 inches deep and weighs less than 1
pound. It can be mounted on a desk, table, or wall. The
unit operating temperature range is -40°Cto +70°C.

Other power supplies may not conform
to this convention.
When using plug-in cards that only require
one pair (i.e., ATRAN FNID, P/N 1242042L),
use one set of loop connection screws
only
(Loop 1 for the FNID).

3. INSTALLATION
3.1 After unpacking the unit, immediately inspect it
for possible shipping damage. If damage is discovered,
file a claim immediately with the carrier, then contact
ADTRAN Customer Service (see subsection 7).
Componentsshippedwiththeunit includethefollowing:
• T400 chassis (including RJ-48C jack)
• RJ-48X jack (shipped loose)
• Three #8 screws
• Wall mounting template
3.2 TheT400 chassis is designed to bewallordesk
mounted.Forwall mounting,three #8screwshavebeen
included. Select a suitable position on a wall or desk for
installation.
Figure 4 indicates the keyhole mounting in the
base of the chassis. The three mounting screws should

surface, leaving a clearance of at least 1/4inch, and no
greater than 1/2inch.
A mounting template is provided with each unit
toassistinlocatingthedrillholes.Thetemplateattaches
to the wall by a tape strip located across the top of the
template.Removethetemplatefromthewallafterusing.
After the screws have been secured, place the
unit over the screw heads and pull the base gently
downward topositionthescrewheadsonthenarrowslot
of the keyholes. If necessary, the screws may be
tightenedby lifting thetopcover and torquingthescrews
from inside the base of the unit.
4. CONNECTIONS
4.1 Connections
The terminal barrier strip is used to make
connections to the housing. The terminal strip is
connected to the edge card connector to interface the
connections to the circuit card. Table B describes the
pinout of the edge card connector in relationship to the
barrierstrip. TheRJ-48jackalongwiththeterminalstrip,
provides for CPE connection.
4.2 Power
The T400 Housing is designed to house a loop-
powered or locally-powered circuit card. The terminal
barrier strip provides the ability to connect an external
-48 VDC supply to the circuit card. These connections
are made to the -48 V and GND on the barrier strip (see
Figure 2). Connection from the barrier strip to the edge
card connector is described in Table B. A ground lug
(see Figure 2) is provided to connect an external frame
ground wire to the unit.
