150-504-100-03 Overview
HRE-504 List 1, List 1B, and List 2 August 1, 2002 1
OVERVIEW
The ADC®HRE-504 List 1, List 1B, and List 2 are outdoor, stainless steel, weatherproof enclosures designed to
house up to four HiGain®remote or doubler units. The HRE-504 is part of a HiGain system.
FEATURES
The following features are included on the HRE-504 weatherproof enclosures:
•Four doubler card slots
•30 foot (9.14 m) gel- or air-filled 28-pair cable stub (HRE-504 List 1 and List 2) or 100 foot (4,000 m)
gel-filled 28-pair cable stub (HRE-504 List 1B)
•Flat surface, rack, or pole mount
•Primary surge protection
•Seamless stainless steel cover
•Single stub access
•Unique card guides automatically adapt every slot to three mechanics
APPLICATIONS
The primary application of the HRE-504 remote enclosure is to house HiGain doubler units in an HDSL/T1
transmission system. The HRE-504 is an outdoor enclosure with four single-width mechanical slots. It has a single
gel-filled stub (HRE-504 List 1 and List 1B) or air-filled stub (HRE-504 List 2).
The gel-filled unit is intended for aboveground pole mounting applications that do not require pressurization
through the cable stub. However, if you prefer to pressurize the unit, it can be locally pressurized by an optional
pressure relief valve, as shown in Figure 1 on page 2.
The air-filled unit is intended for underground installations. It can be pressurized from the main feeder cable
through its air-core stub. The pressurization prevents the enclosure from flooding when mounted in underground
manholes.
Both units have primary gas-tube surge protection on all cable pairs.
The HRE-504 can be used to house the following doubler and repeater units:
•HDU-439, HDU-437, HDU-409 or HDU-407 Full T1 unit (1.544 Mbps)
•HDU-219 or HDU-217 Fractional T1 unit (0.772 Mbps)
•EDU-842 ETSI unit (2.048 Mbps) and EDU-409 E1 unit (2.048 Mbps)
•ISDN repeater
•DDS repeater
•239 T1 repeater
All doublers and repeaters share the same generic slot pair assignments as shown in Table 1 on page 16.

PRESSURIZED APPLICATIONS
For pressurized applications on the HRE-504 List 2, the Schrader air stem valve isused. A pressure gauge attaches
to the valve for the purpose of measuring the internal pressure of the enclosure. This valve is also used to relieve
the internal pressure prior to opening and removing the dome cover. This can be done by depressing the center pin
on the valve. Figure 1 below and Figure 2 on page 3 show the Schrader air stem valve location.
Figure 1. HRE-504 List 2 Air-filled Remote Enclosure
An optional breather vent assembly is enclosed in the air-filled HRE-504 List 2 shipping kit. The kit is a small
plastic bag attached to a red and brown-colored spare pairs shrink tube. The breather vent replaces the pressure
relief valve, if the air-filled unit is not pressurized. The assembly allows the enclosure to breathe and keeps the
internal atmosphere free of harmful contaminants. Figure 2 on page 3 shows the four metal valves.
This depressurizing must be performed every time the cover is removed from the enclosure.
Failure to do so may cause personal injury or damage to the equipment.
Unlike the gel-filled unit, the pressure cutoff valve in the air-filled unit cannot be used to cut off
an external source that is applied to the Schrader air stem valve. The air-filled unit pressure
cutoff valve can only control the air source that is applied to the enclosure through the air core
stub.
