6.5.5.2 TRMS Installation
Any RF cable, which is terminated with a SMA connector, should be
tightened with a 5/16” torque wrench to avoid over tightening and
damaging the cable connector or mating connector.
The replacement TRMS should be installed in the following sequence:
1. Slide the replacement TRMS into the open slot in the LB cabinet electronics
compartment above the LBE.
2. Replace the four (4) Phillips pan head screws which secure the TRMS to the mounting
rails – see Figure 6-7
.
3. Re-connect the wires/cables to the TRMS rear panel in the order that they appear in
Table 6-6
.
4. Switch ON the TRMS circuit breaker (CB 8), located on the LB cabinet PDU front panel.
5. Switch ON the TRMS rear panel power switch.
6. Please refer to SiriusXM instructions as well as the TRMS Operating Manual to
configure the TRMS with specific settings for its assigned location.
7. Close the electronics compartment front and rear doors.
