The rack-mountable Host is typically located with the RF source—a Base
Transceiver Station (BTS). The Host is DC powered and supports up to eight BTS
interfaces through DART (Digital/Analog Radio Transceiver) cards. (For further
information on DART Modules, see
“DART Modules” on page 24
.)
The Host is designed for use within a non-condensing indoor environment, such
as inside a base-station shelter, Central Office, wiring closet, or a
controlled-environment cabinet. It is installed into a 19- or 23-inch, rack-mounted
chassis, that is 9-inches deep and can hold up to three units. All controls,
connectors, and indicators, except for the grounding point, are accessible on front
of the Host.
Figure 7
shows the main elements of the Host.

NOTE:
The Host comprises a Fan Assembly, a SeRF II Board Module, a Host System II Module,
and a DC Power Module. These modules are pre assembled in the Host chassis at the
factory. This document describes them as separate modules for reference only.
Fan Module
The Fan Module, mounted on the left side of the Host, continuously blows cool air
into the Host enclosure, and vents hot air out of the chassis on the right. An alarm
is generated if a high-temperature condition occurs. The Fan Module is field
replaceable (see the Prism Host Unit Installation Guide, ADCP-77-089).
