The indoor RU is designed for mounting in a non-condensing indoor environment such as
inside a wiring closet or within an environmentally-controlled cabinet. The indoor RU is
intended for rack-mount applications and may be mounted in either a 19- or 23-inch WECO or
EIA equipment rack. The indoor RU consists of a Spectrum Transport Module (STM), a Linear
Power Amplifier (LPA) module, and a mounting shelf that supports the modular components.
The mounting shelf installs in the equipment rack. Slots are provided in the mounting shelf for
the STM and LPA modules. Slots are also provided for mounting the WDM or CWDM remote
module (accessory items).
