ADTRAN T200 H2TU-R Status Indicator LEDs, Door Power LED, FAN Thermostat LED, Installation

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.

NOTE

The door switch also controls intrusion detection on the FPU at the CO.

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.

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.

Cabinet location should be selected with the following in mind:

Personnel and equipment safety

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
