an outdoor, above-ground enclosure. Up to 24
61150090L1-5A Section 61150090L1-5A, Issue 1 1
Trademarks: Any brand names and product names included in this document are
trademarks, registered trademarks, or trade names of their respective holders.
ADTRAN Line Powered T200 or T400 Circuit Packs
can be installed per cabinet. The cabinet system is prewired with surge arrestor boards to reduce installation
and turn-up time. Wiring consists of either pre-wired
cable stubs or pre-wired internal splice module
connections depending on the model.
The cabinet body is constructed of aluminum with a
powder coated gray finish. Earth ground connects to
the ground lug on the bottom of the cabinet. The nonvented enclosure protects the internal electronic
circuitry from the surrounding environmental
conditions.
For the pad mount model, the cabinet sits on two
bolt-on mounting brackets. The brackets are in-turn
bolted to the craft designated pad. The front and back
security access panels are then bolted to the brackets
to provide a secure enclosure for the wire runs exiting
the bottom of the cabinet.
All models incorporate tamper resistant access with
lockable front and rear cabinet doors, replaceable
surge arrestor gas tubes, and replaceable fan modules.
Features
The T200/T400 High Capacity Cabinet includes the
following features and components:
• Two 19 inch T200/T400 chassis with 24 slots
(2x12) for line powered T400 or T200 Circuit
Packs.
• Line powered internal cooling fans.
• Pre-wired 50 foot cable stubs, or internal splice
module connections, depending on the model.
• Pre-installed splicing modules on cable stub
ends or wiring harness for fast, simple
connections at the customer’s site or splice case.
• Surge arrestors are provided for each slot with
replaceable gas tubes.
• Gas tube extraction pliers.
• Moisture absorbing desiccant.
• Spare cable hole entrance with removable seal.
• Mounting template for craft planning.
Cabinet Access
The front and rear cabinet doors and support bracket
access panels include tamper resistant security
fasteners. The cabinet doors allow for a customer
supplied lock for added security. The front door
provides access to insert and remove the circuit packs
and desiccant bags. The rear door provides access to
the chassis backplane, cable and wire connections, fan
boards, and surge arrestor boards. All cable
penetrations are through the bottom panel.
When opened, the front and rear door switches
provide intrusion detection at the Central Office FPU
(Fan Power Unit). The door switch can then be
manually positioned to disable intrusion detection.
The door switch automatically resets when the door
closes. Retainers hold the door open until they are
manually released. Front and rear door features are
identical. Refer to Figure 2 for cabinet details, rear
view.
Mounting
The Cabinet is pad or pole mountable depending on
the model. The cabinet is for above ground use only.
The pad mounted model includes two interchangeable
boxlike brackets that raise the cabinet 18 inches above
the pad to allow easier access, provide additional
clearance for manipulating cables, and protection from
a high water condition. Pole mounting is
recommended where water conditions could reach a
pad mounted cabinet.
Mounting Template
The pad mounting footprint dimensions are provided
as a full size template on the unit’s packaging, and
complete installation measurements are shown in
Figure 3.

Fan Operation and Indication
Two thermostatically controlled line powered cooling
fans limit heat buildup. The primary fan energizes at
about 110° F. The secondary fan energizes at about
150° F.
Primary and secondary fan board operation is
monitored by the FPU. The following conditions
cause an alarm at the FPU:
• Any fan or fan board not receiving power.
• Secondary fan turning On.
• Open cabinet door.
The single FPU at the CO has a separate power supply
for each fan board. The FPU fits into one slot of the
E220 HTU-C shelf (for HDSL applications).
The FPU is purchased separately. Information on fan
board operation and testing is in Section 3. For
additional details on the FPU refer to I&M Practice:
61150091L1-5. The FPU Practice should be on-hand
at the CO for reference during cabinet testing.
61150090L1-5A Section 61150090L1-5A, Issue 1 3
NOTE
Because heat dissipates across the cabinet
surfaces, the cabinet should not be installed
within another enclosure or hut unless such
enclosure has positive ventilation.
Status Indicator LEDs
Each fan board has two status indicator LEDs:
• DOOR LED (Red), verifies that FPU power is
present on the associated fan board.
• FAN LED (Green), verifies the open or closed
position of the fan’s associated thermostat.
The LEDs give positive indication that power is
present to operate the fans and thermostats.
DOOR (Power) LED
Power is present at the corresponding fan board if the
red Door LED turns On when the door is opened as
explained here:
• When the front door is opened, the secondary
fan board red Door LED turns On until the front
door switch is manually disabled or the front
door is closed.
• When the rear door is opened, the primary fan
board red Door LED turns On until the rear door
switch is manually disabled or the rear door is
closed.
2. INSTALLATION
C A U T I O N !
SUBJECT TO ELECTROSTATIC DAMAGE
OR DECREASE IN RELIABILITY.
HANDLING PRECAUTIONS REQUIRED.
The cabinet assembly weighs about 200 pounds. This
Practice assumes that proper lifting devices are on
hand for maneuvering and holding the cabinet in
position until securely mounted.
After unpacking the T200/T400 High Capacity
Cabinet inspect it for damage. If damage is noted file
a claim with the carrier, then contact ADTRAN
Customer Service (refer to Section 5).
WARNING
Never install telephone wiring during a
lightning storm.
If equipment is to be stored for any period of time,
ADTRAN recommends that the equipment be kept in
the original shipping container until arriving at the
installation site.
CAUTION
Although sealed from the elements the cabinet
is not designed to be waterproof and must not
be located where any type of immersion could
occur.
NOTE
The door switch also controls intrusion
detection on the FPU at the CO.
Cabinet location should be selected with the following
in mind:
• Personnel and equipment safety
FAN (Thermostat) LED
The green LEDs indicate that power is present at the
thermostat by being On when the fans are Off.
When the thermostat is Open, the green FAN LED
should be On and the fan should be Off. When the
thermostat is Closed, the FAN LED should be Off and
the fan should be On. FAN LED operation is
independent of door switch status.
• Personnel access
• For cable stubbed versions, the proposed cable
routes should not exceed the 50-foot cable stub
lengths.
• Clearances between the cabinet and adjacent
structures must be adequate for access during
maintenance (refer to pad and pole mount
subsections).
Pad Mount Installation
Pad configuration is designated by the installing
activity. The cabinet shipping box has a printed
template for support bracket bolt hole location. Craft
planning will ensure the pad four bolt pattern matches
4 Section 61150090L1-5A, Issue 1 61150090L1-5A
the bracket pattern. Refer to Figure 4 for pad mount
