If a site is configured with RFUs and RRUs, the RRUs and their cables must be installed onsite. For details, see the related RRU installation guide.
11.11 Installing the AC Heater
When the environmental temperature of a cabinet is low, the cabinet can be configured with a heater so that the temperature in the cabinet is kept in a proper range. This section describes the procedure for installing a heater in an APM30H or TMC11H.
11.12 (Optional) Installing the HAU01A-01
This section describes the procedure and precautions for installing the HAU01A-01 and its related cables.

l In the following figure showing the digital distribution module, a, b, and s have different meanings.
– a and b indicate signal cables. – s indicates a PGND cable.
1. Insert the bare wires at one end of the twisted pair cable to the corresponding digital distribution module according to the colors and labels of the wires.
2. Use an impact tool to seat the wires of the twisted pair cable into the terminal blocks on the DDF, as shown in Figure 11-22.
Step 2 Distribute the twisted pair cable on the DDF on the peer equipment side. This twisted pair cable is connected to the peer equipment.
1. Insert the bare wires at one end of the twisted pair cable to the corresponding digital distribution module according to the colors and labels of the wires.
2. Use an impact tool to seat the wires of the twisted pair cable into the terminal blocks on the DDF, as shown in Figure 11-22.
Step 3 Arrange the wires on the DDF, as shown in the following figure. Figure 11-22 Cabling on the DDF
NOTE
l After distributing cables on the DDF, ensure that no bare wire is exposed outside the DDF. l When interconnecting cables on both sides of the DDF, interconnect wires according to actual
situations. The colors of interconnected wires must be the same, as shown in Figure 11-22.
Step 4 Optional: If there is a filler module in the installation position for the SLPU, remove the filler module, as shown in the following figure.
1. Use a Phillips screwdriver to remove the two M6 screws from the mounting ear on each side of the filler module.
2. Slide the filler module out of the cabinet.
NOTE
The removed filler modules must be installed in the vacant slots in the lower part of the cabinet from top down. If vacant slots are all occupied with filler modules, other redundant filler modules are discarded.
Figure 11-23 Removing the filler module
Step 5 Check whether floating nuts are installed on both sides of the 19-inch rack. If no, install the floating nuts delivered with the DDF to both sides of the rack.
Step 6 Align the DDF with the cabinet, slide it into the cabinet, and use a screwdriver to tighten two M6x12 screws on each side of the DDF to 2 N·m (17.70 lbf in.), as shown in the following figure. Figure 11-24 Installing the DDF
11.5 Installing the Batteries
This section describes the procedure and precautions for installing the batteries and related cables in the IBBS200D, IBBS200T, IBBS700D, and IBBS700T.
Prerequisites
