OVERVIEW
The HiGain®HRM-238 List 1 is a two-slot HiGain Retrofit Management (HRM) shelf. This shelf fits into either
a 19- or 23-inch Central Office (CO) equipment rack. It accommodates up to two HiGain management units
(HMU-319s). It is used in conjunction with 220-type, unmanaged 3190 type, and DDM+ type mechanic shelves
to manage HiGain line units.
The HRM-238 shelf, with two management units installed, provides network management capabilities for a
maximum of 56 HiGain line units (one 3190 or DDM+ or two 220 shelves). Each management unit in the
HRM-238 shelf can manage up to 28 line units.
The HMU-319 management unit installs horizontally into the 4 ¾-inch slots labeled A or B on the HRM-238 shelf
(Figure 1). Each management unit connects to the shelf backplane through a 96-pin DIN connector.

FEATURES
Standard features include:
•50-pin Amp-type connectors for connection between the management units in the HRM-238 shelf and
previously unmanaged HiGain line units in 220, 3190, or DDM+ mechanics shelves.
•DB-25 connectors for connection to a computer, terminal, or modem
•British Naval Connector (BNC) for connection to a Local Area Network (LAN) or to a HMU-319 multi-shelf
connection
•screw-type terminals for -48 Vdc power connection and grounding
•23 wire-wrap pins to monitor alarm relay activity

OPERATIONAL CAPABILITIES
Application
With two HMU-319 management units installed, the HRM-238 shelf provides network management for up to 56
HiGain line units.
Recommended Network Setup for 220 Type Shelves
The configuration shown in Figure 2 is the recommended setup for 220 type mechanics shelves. Position the
HRM-238 shelf between the 220 type shelves, with up to two 220-type shelves above and two below. This limits
the distance for the wire leads between the connectors for the management units and the line units they manage.
Figure 2 shows the HRM-238 shelf from the rear view with the A-side connectors on the right and the B-side
connectors on the left. The leads from the HRM-238 shelf connector attach to the Network Management Agent
(NMA) pins on the rear of the 220-type mechanics shelves for each line unit managed. The NMA pin on 220 type
chassis is pin 46.
