Figure 2-5. Remote Unit Indoor Mounting Shelf
4.2 STM and LPA Module Installation
Two mounting slots are provided within the indoor mounting shelf for installing the STM and
LPA modules. The mounting slots include tracks that guide each module into the installed
position. Separate mounting slots are provided for STM and LPA modules. Two D-sub
connectors (one male, one female) are located at the rear of each mounting slot. Each mounting
slot connector mates with a corresponding D-sub connector located on the rear side of each
module. A wiring harness links the mounting slot connectors together. The connectors and the
attached wiring harness provide the electrical interface between the STM and LPA modules.
The modules are held in the installed position with captive screws.
4.3 WDM and CWDM Installation
Mounting slots are provided in the indoor mounting shelf for installing a WDM or CWDM
module (accessory items). Each module is equipped with push-pull type fasteners for securing
the module to the mounting slot. A power cable is included with the mounting shelf for
supplying DC power when a CWDM module is installed.
4.4 Fiber Optic Cable Installation
Fiber optic cables and patch cords should be routed to the indoor mounting shelf using existing
fiber management systems. All fiber optic connections are made directly with the STM, WDM,
or CWDM modules. It is recommended that some provision be made at the mounting shelf for
storing excess patch cord slack.
