AN2016 cabinet structure
The basic NTNR01AA AN2016 cabinet structure consists of the following
items:
• cabinet physical design
— exterior
— doors and door locks
— cable access ports
• heat exchangers
• environmental control unit (ECU)
• cable routing brackets
• equipment compartment
• AC compartment
— battery distribution and disconnect panel
• surge protection center (SPC) and termination compartment
— VF and DS-1 protection blocks
• Battery compartment
— battery heater pad
Cabinet physical design
This cabinet can house up to three 672-line systems of Nortel Networks
AccessNode equipment. The four supported configurations are described in
the following sections of this chapter. The cabinet features an enclosed
equipment compartment with separate compartments for the outside plant
cable termination and commercial power entrance. The AN2016 cabinet has a
split base assembly designed to house the batteries for the battery backup.
A mounting template aligns the cabinet openings and the mounting bolts to a
concrete pad. Pad mounting bolts secure the cabinet to the concrete pad and
are accessible by opening the SPC and AC compartments.
Note: The pad mounting template is a required separate kit which you
must order ahead of time for site preparation.
Exterior
The exterior structure of the AN2016 cabinet, including the shell, exterior
walls, and floor is primarily constructed of powder-coated 1/8-inch thick
aluminum measuring 113.45 in. (288.16 cm) wide by 46.34 in. (117.7 cm)
deep and 71.25 in. (180.97 cm) high. Other parts, such as the equipment
frames, use thicker materials.

2-6 Equipment
AN2016 Cabinet User Guide Rel 1.0 Standard May 1999
Doors Six doors enable you to access the AN2016 cabinet:
• one each for the SPC and AC compartments
• two sets of double doors for the equipment compartment
The equipment compartment is accessible through overlapped hinged outside
doors. You can access the battery compartments and end compartment
kickplates from the equipment compartment or the end compartment.
Door locks
All hinged exterior doors are designed to be locked through a multi-point
locking mechanism to ensure that all door corners and edges are secure. The
locking mechanism contains a padlock hasp that can accept a 1/4 inch diameter
padlock shackle.
When the door locks are enabled, the front and rear equipment, the AC, and
the SPC and termination compartment doors can be opened with a 216-type
socket tool.
Note: Each door locking mechanism is disabled at the factory prior to
shipment.
The door locking mechanism prevents water intrusion into the cabinet.
Intrusion and system failure alarms are provided to a remote alarm monitoring
center. A local intrusion alarm is provided to work in conjunction with the
remote alarm.
Cable access ports
Four cable access ports are provided in the base of the surge protection center
(SPC) and termination compartment. These ports have 4 inch (10.16 cm)
inside diameter split-sleeve openings which facilitate the entrance of metallic
and optical fiber cables. One 1/2 inch (12.7 mm) grommet opening is also
provided for grounding purpose.
Two additional cable access ports are provided in the base of the AC
compartment. These ports have 4 inch (10.16 cm) inside diameter split-sleeve
openings. One 2 1/2 inch (63.5 mm) opening is provided for ac conduit.
Cable entrance seals prevent water intrusion into the compartments.

Equipment 2-7
User Guide Rel 1.0 Standard May 1999
Heat exchanger system
The equipment compartment is equipped with the air to air heat exchanger
system.Thesystem operate in a closedloopcooling methodwithseparatefield
replaceable fans for the internal and external flow paths.
Three heat exchangers provide a total cooling capacity of 4800 watts. Each
heat exchanger is equipped with internal and external fans which are powered
independently of one another. The external fans draw exterior air through the
bottom of thecabinet and exhaust it out into the air chamber in the cabinet top.
The internal fans draw interior air from the top of the equipmentcompartment
and exhaust it out the bottom of the chamber (see Figure 2-4).
Environmental control unit
One environmental control unit (ECU) is provided as part of the cabinet to
sense, control and report the internal climate of the cabinet (see Figure 2-5).
The ECU monitors and controls thermistor input for up to seven fan shelves,
ECU alarms outputs for high temperature, intrusion and system failures.
The system controller regulates each fan shelf and eachheatexchanger internal
and external fan group independently. Fans can be individually enabled or
disabled using dip switches to allow normal operation, even if the system does
not contain all the fans. Each fan group can have different temperature set
points using a single thermistor input. If the ECU fails to operate, the external
thermostat activates the fans.
The ECU has 12 bicolor light-emitting diodes (LEDs) to indicate the status of
the ECU and attached accessories. When all LEDs are green, the system is
running in the temperature control mode with no failures. Except for High
Temp, Intrusion and Mode LEDs, a red LED indicates failure of the labeled
device. If the high temp LED is Red, the thermistor is reporting a temperature
in excess of the set point. If the Intrusion LED is Red, a door has been opened.
If the Mode led is Red, the system has been overridden and the fans should be
on. The ECU is mounted on the lower baffle in frame/bay F.
The ECU has a start up and initialization routine when:
• The reset switch is pressed, which is located next to the heat exchanger
(HX) fan 1 LED on the front panel. This will cause a restart.
• The software locks up and the watchdog timer (WDT) times outand forces
a reset and a restart.
• When power is first applied, the power on reset causes a reset and start up
begins.
To verify the operation of the ECU, refer to the start up and initialization
routine, see Procedure 5-7,”Starting up the ECU”.
