HRE-204 List 1 and List 2 May 7, 1999 1
OVERVIEW
This document describes the ADC®HiGain®Remote Enclosure HRE-204 List 1 and List 2. The HRE-204 List 1
and List 2. List 1 and List 2 house HiGain Line Units (HLUs) and remote units (HRUs). The HRE-204 List 1 and
List 2 List 1 has RJ48C DS1 connectors, and the HRE-204 List 1 and List 2 List 2 has RJ48X connectors.
FEATURES
The HRE-204 List 1 and List 2 List 1 and List 2 provide the following features:
•four 200 mechanics or two 400 mechanics slots
•optional RJ48C (List 1) or RJ48X (List 2) modular jack for DS1 customer interface connections
•printed-circuit backplane provides terminal block or RJ48 connectors
•tamper-proof locking screw for security
•accepts 48 V input power for HLU applications
•wall or desktop mounting
•separate 48 V input terminals for slot isolation
•optional wall hinge mount
•pre-painted, cold-rolled, #16 gauge steel construction
APPLICATIONS
HiGain provides a quick and cost-effective way of delivering T1 High Capacity Digital Service (HCDS) to
customers over metallic cable pairs. The primary application of the HRE-204 List 1 and List 2 Remote Enclosure
is to house the remote units of a HiGain repeaterless T1 transmission system.
Because the HRE-204 List 1 and List 2 uses standard 200 and 400 mechanics slots, it can
accommodate anyplug with 200 or 400 mechanics, including the HiGain HRU-412, HRU-411, and
HRU-402 remote units and the HLU-431 line unit.

MOUNTING OPTIONS
The HRE-204 List 1 and List 2 is suitable for mounting on a desktop or on a wall. Before setting up the equipment,
select a location that will provide appropriate security.
Desktop Mounting
The remote enclosure includes four inverteddimples in the bottom plate fordesktop mounting. Thedimples create
an air gap between the bottom of the enclosure andthe surface of the desk. This prevents overheating by providing
air flow through the enclosure. Do not block the air flow from the bottom of the unit.
Wall Mounting
To mount the enclosure on a wall, loosen the backplate and use it as a template for the two mounting holes as
follows:
1Loosen the 216 HEX security nut on the side panel (Figure 4) with a 7/16-inch CAN wrench.
Figure 4. Side Panel Assembly
2Remove the side panel.
3Remove the top retaining screw that holds the backplate to the chassis.
Regardless of where the HRE-204List 1 and List 2 is mounted, ADC recommends that the frame
ground lug be connected to earth ground according to the grounding recommendations found
in Section 9 of Bellcore’s GR-1089-DEC, 1996. See “Power and Grounding”on page 9 for more
information.

4Grip the top of the rear panel, which is held in place with corner friction clasps, and unlatch it from the
enclosure.
5Use the backplate as a template to mark the wall locations for drilling the mounting holes (Figure 5).

6Drill pilot holes and attach the backplate to the backboard with the two No. 10 x 5/8-inch sheet metal screws
and washers supplied with the remote enclosure.

7Rotate the main chassis up and snap it into the backplate friction clasps (Figure 6).
Figure 6. Wall Mounting and Hinging View
8Reattach the side panel and tighten the 216 HEX security nut to secure it to the main chassis.
When the main chassis is attached to the backplate, it can be rotated down to provide access
to the backplane connector and other internal areas. Unlatch the chassis from the two friction
clasps in the upper corner of the backplate to lower it. See Figure 6 for hinging details.

Optional Hinged Wall Mounting
To reduce the forward profile of the normal wall mounted HRE-204 List 1 and List 2, a wall mount hinge
assembly, part number 150-2224-01, is available to attach the side of the unit flush to the wall. This reduces the
outward projection from 7.5 inches to 4.8 inches.
1Use the hinge as a template to mark the wall location for drilling the mounting holes.
2Drill pilot holes and attach the hinge to the wall with the two No. 10 x 5/8-inch sheet metal screws supplied
with the hinge assembly.
3Use the two 6-32 x 1/4machine screws, also supplied with the hinge assembly to attach the hinge to the two
mounting holes on the HRE-204 List 1 and List 2 backplate, as shown in Figure 7.
Figure 7. Optional Mounting Hinge
4The two snap-in standoffs on the hinge bracket fit into two mounting holes in the HRE-204 List 1 and List 2
side panel when the enclosure is closed against the hinge. This secures the HRE-204 List 1 and List 2 to the
hinge and prevents normal vibration from jarring it loose.

TURN-UP
Follow these steps to complete the turn-up procedure:
1Loosen the 216 HEX security nut on the side panel (Figure 4 on page 5) with a 7/16-inch CAN wrench.
2Remove the side panel from the chassis to expose the card slots.
3Insert the card in the assigned slots and refer to the card’s technical practice for the appropriate turn-up
procedure.
If you are using the HRE-204 List 1 and List 2 to locally power one or more HRUs or HLU-431 Line Units,
see “48 Volt Power Options”on page 9. If you install an HLU-431 Line Unit into the HRE-204 List 1 and List 2,
see “HLU Alarm Output Interface”on page 14 for information about the alarm output interface.
POWER AND GROUNDING
The chassis frame and pins 1 and 17 (slot frame ground) of each slot are connected to the HRE-204 List 1 and List
2 ground lug G1, located on the backplane, as shown in Figure 1 on page 2. ADC recommends that the frame
ground lug be connected to earth ground according to the grounding recommendations found in Section 9 of
Bellcore’s GR-1089-DEC, 1996.
48 VOLT POWER OPTIONS
When using the HRE-204 List 1 and List 2 to locally power HRU plugs or HLU-431 line units, the 48 V power
can be provided in either an isolated or non-isolated mode. Power is provided to terminal blocks TB3 and TB4,
the pin assignments for which are shown in Figure 8 on page 10.
The isolated mode requires two separate external power supplies, which are connected to TB3 for Slots 1 and 2,
and to TB4 for Slots 3 and 4. This isolated mode prevents the loss of all circuits if one power supply fails.
Failure to properly ground the enclosure can cause unsafe voltage levels to occur which can
result in the following adverse situations:
•a shock hazard to craft personnel who come into contact with the enclosure
•damage to the installed circuits if the normal discharge path to earth ground of the
enclosure’s secondary surge voltage protection components is missing
•bit errors due to the inability of the ungrounded enclosure to attenuate the noise inducing
energy from stray EMI fields
•bit errors due to crosstalk from adjacent communication equipment.
In certain unusual noise environments, it may be necessary to connect the HRU’s circuit ground
pin 17 to frame ground pin 1 of the card-edge connector to remove bit errors from the T1
payload.

Power and Grounding 150-204-100-03, Issue 3
10 May 7, 1999 HRE-204 List 1 and List 2
The non-isolated mode only uses one power supply, but has no failsafe feature, since all circuits are lost if the
power supply fails. To connect a single power supply for non-isolated mode:
1Connect the power supply to either TB3 or TB4.
2Connectthe equivalent pinsoftheunused terminalblockto theactiveterminal block.Thisconnects thepower
source to all slots.
Figure 8. TB3 and TB4 Pin Assignments
Third party wall mount power supplies can be used to provide 48 V power for various plug applications, as shown
in Table 2.
