When inserting the OIM into the BDM, make the interface of the optical module on the
OIM face outward to ensure that optical fibers can be inserted into the optical module
of the OIM from the right side of the BDM, as shown in Fig. 10.3-5.

10.3.5 Installation of LFM
If a remote station need be configured for a macro-BTS, it is only necessary to replace
TRX of a sector with LFM by just inserting LFM into the TRX slot in the TRX layer of
the macro-BTS without changing any cable connections on the backplane. The RF
modules such as TRX, HPA and RFE need not be installed in the macro-BTS.
Refer to “7.2.1 Connecting Optical Fiber” for the connection with LFM and the
cabling of optical fibers in a macro-BTS.
10.4 Points for Attention
1. Main tool: Philips screwdriver.
2. When installing MPA and MPD400W, cover the place between the
MPA/MPD400W and the main radiator with silicon.
3. The modules should be installed firmly and reliably.
