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).
1Position 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.)
2Align the HRM-238 shelf mounting brackets with the vertical mounting holes on the CO rack (Figure 6).
3Install the mounting hardware and secure.

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.
