3.5 2000 Lite Installation and Connections
MA 2000 Lite is designed to be a wall mounted device. It is usually installed in the
communication shaft of the corresponding floor and is powered from an external power
source. It may also be connected to a backup battery.
The remote units are mounted externally to the 2000 Lite device and their antenna outputs
are connected to either side of the 2000 Lite device. The combined outputs are then
connected to the antennas in the covered area.
2000 Lite is capable of supporting two types of remote units: RU 2000 and MA 850
(wireless 802.11a/b/g coverage). A MA 1200 add-on module can be connected to each RU
2000 module to provide additional services.
The MA 2000 Lite connections are shown in the following figures. Note that the power
connections are on the underside, and the coax connections are at the sides of the modules.

4.1 Overview
This chapter describes each of the system elements, and their individual connections. It can
be used as reference to verify the connections of each module or to upgrade your system. In
order to describe the installation process clearly, it will be described as consisting of two
logical parts:
A. Telecommunications room – installing the RIUs, BUs, MA 410/430
controllers, and the required
room close to the RF signal source. This installation may differ between single
and multi-building topologies.
B. Remote locations – RC installations and connections. These are
mounts.
The installations for two basic topologies are described in detail: for single building and for
multi-building. By understanding the two generic installations you will be able to address any
variations in system deployment.

4.2 MA 2000 Remote Cabinet
The MA 2000 Remote Cabinet can house various combinations of up to five RU 2000 and MA
1200 add-on modules. The number of modules depends on the models, required filtering,
etc. In addition, a MA 850 module may be installed externally. The Remote Cabinet provides
the filtering, combining, power interface and antenna interface functions.
NOTE: If an MA 860 module is installed as well, the antenna outputs are further connected
to the appropriate connec ions on the MA 850 and the antennas then connec ed to the MA
850 antenna connections.
The optic connection from the BUs are routed internally and connected directly to the
corresponding RU 2000 module.
The MA 2000 Remote Cabinet is provided in two power configurations:
• Integrated power supply – a power supply is integrated into the cabinet and fed
from an external AC power source. The individual modules are internally connected
to the power supply. This model includes a battery connection as well.
t t
• External power supplies – the power source is external to the cabinet: it can be from
a central remote source (most common configuration) or from local installed
dedicated power supplies. Power is routed to external connectors on the Remote
Cabinet, where each external power connector is internally connected to a specific
module.
The cabinet may be mounted on a wall or in a 19” rack. The appropriate brackets are
provided with each type of installation.

4.3 MA 2000 2000 Lite Installation
The 2000 Lite provides the required interface and filtering required to support two RU 2000
modules to which MA 1200 add-on modules can be connected for additional services. This
MA 2000 configuration is fed from external power supplies. The RU 2000 modules, the
dedicated power supplies and any MA 1200 add-on modules are installed externally to the
2000 Lite.

3. Connect the remote module optic fiber connections.
4. Connect the antenna coax infrastructure cables to the 2000 Lite connectors.
4.4 Remote Modules
The Optical to RF conversion of each service at the individual building floors is performed by
Remote Units (RU) 2000 modules corresponding to the service types. These consist of MA
2000 RUs and in addition, may include MA 1200 and MA 850 modules.
The location installations may be performed in various configurations depending on the
requirements of the site and the supported services. If a Remote Cabinet installation is
performed, the RU 2000 and MA 1200 modules are housed inside the cabinet while the MA
850 module is installed externally and integrated into the system. If a 2000 Lite installation is
performed, the modules are installed externally to the enclosure.

The following sections describe each of the elements and the connections as they relate to
the MA 2000 system.
4.4.1 Remote Units 2000
Each RU supports two different services (one high-band and one low-band). All RUs are
add-on ready, meaning that an additional (high-power) service can be added by connecting
a 1200 add-on module to the RU.
A fiber optic connection is implemented between each RU 2000 and corresponding BU. The
RU may be remotely monitored through the corresponding BU connection to the MA NMS.
The RU 2000 services, MA 1200 add-on service and MA 850 data services at each location
are combined prior to transmission to strategically placed antennas.
