Overview  
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.

Overview  
Recommended Network Setup for 3190 Type Shelves  
The configuration shown in Figure 3 is the recommended setup for 3190 type mechanics shelves. Position the  
HRM-238 shelf below the 3190 type shelves. This limits the distance for the wire leads between the connectors  
for the management units and the line units they manage. Figure 3 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 3190-type mechanics shelves  
for each line unit managed. The NMA pin on 3190 type chassis is pin 7.

for the management units and the line units they manage. Figure 4 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

INSTALLATION  
INSPECTING YOUR SHIPMENT  
Upon receipt of the equipment:  
Unpack each container and inspect the contents for signs of damage. If the equipment has been damaged in  
transit, immediately report the extent of damage to the transportation company and to ADC  
Telecommunications, Inc. Order replacement equipment, if necessary.  
Check the packing list to ensure complete and accurate shipment of each listed item. If the shipment is short  
or irregular, contact ADC as described in “Appendix B - Product Support” on page 14. If you must store the  
equipment for a prolonged period, store the equipment in its original container.  
INSTALLING THE HRM-238 SHELF  
Install the HRM-238 in a CO equipment bay rack. If the CO rack is 19 inches wide, attach the short side of the  
mounting bracket to the HRM-238 shelf and use the long side of the mounting bracket to attach to the CO rack.  
If the CO rack is 23 inches wide, reverse the mounting bracket. Attach the long side of the mounting bracket to  
the HRM-238 shelf and use the short side of the mounting bracket to attach to the CO rack (Figure 6).  
1
Position the HRM-238 shelf in the CO rack. (See “Operational Capabilities” on page 2, and Figure 2 on  
page 2, Figure 3 on page 3, or Figure 4 on page 3 for recommended placement.)

INSTALLING FRAME GROUND AND BATTERY POWER  
Perform the following steps to install the -48 Vdc battery to the HRM-238 shelf and to connect battery common  
ground (LGND) and frame ground (FGND). The HRM-238 shelf terminal block TB1 has two connection points  
for supplying redundant battery capability. Connect a -48 Vdc battery source to Terminal 1 (-48V_A) to supply  
voltage to the HRM-238 shelf (Table 2 on page 6). Connect another -48 Vdc battery source to Terminal 2  
(-48V_B) to supply redundant voltage to the HRM-238 shelf. See Table 2 on page 6 for TB1 terminal block  
information.

INSTALLING COMMUNICATION WIRING  
All wiring and connections for the HRM-238 shelf are on the back. Figure 5 on page 4 shows the shelf backplane  
and connectors. Connect the NMA wiring from the HRM-238 shelf to each HiGain or Megabit Modem line unit  
that will be managed using the steps beginning on page 7. Then, use the other connectors in “Connect to a LAN  
appropriate for your application.
