PRODUCT DESCRIPTION

1. Product Description

The MPRFA/B MAXNET II module is an RF Detector A/B Switch, which provides redundancy for use of multiple RF Ampliers

or RF Sources. It has an integrated 2-way splitter for easy realisation of redundancy scenarios (see Application Examples –

3.5.). The integrated splitter allows for maximized rack space saving and comfortable cable/signal management.

The MPRFA/B RF Detector switch module is dual-width, taking up two slots in the Active MAXNET II Chassis and it is
powered through a hot-swapping backplane in the Active MAXNET II Chassis. An appropriate MAXNET II Power
Supply in the Active MAXNET II Chassis powers these modules. The MPRFA/B module features the standard

MAXNET II functionality including high-density packaging through the use of MCX coaxial cable connectors in conjunction

with Mini RG-59 Type coaxial cable. Also featured are: front access alarm/status LED indicators, a -20 dB test point
and the capability of module status monitoring through SNMP based Managers. The MAXNET II SNMP interface is
HMS compliant.

INSTALLATION

2. Installation

2.1. Product Inspection

Carefully unpack the switch module from the shipping box. If the box or switch module is damaged, please notify the freight
company to make a damage claim. If you suspect that there is a problem with the switch module that may affect it’s safe
operation, do not install such a suspect Switch into the Active MAXNET II Chassis.

2.2. Module Installation into the Active MAXNET® II Chassis

Slide the dual-width MPRFA/B switch module into an open slot in the Active MAXNET II Chassis, one that spans two single­width module locations beginning with an odd number (indicated by a white marker on the chassis), until the module drops
into its lock position. The module must be inserted into an odd number slot in order for the switch module to properly
mate to the active chassis back plane. If the module is installed properly, the switch will make contact with the 24 VDC
power bus in the chassis and if there is a MAXNET II Power Supply Module installed in the chassis, and it is plugged into
the respective power source, the module’s PWR (Power) LED indicator will light green. To remove a switch module from the
chassis, gently lift the front handle and pull back on the module until it is clear of the chassis guide slot.

Initially, when inserted in the Active MAXNET II chassis, the switch will start alarming (the front panel A LED indicator will start

ashing red), as there are no RF input signals. The switch will stop alarming (the front panel A LED indicator will stop ashing
red) once RF signals are applied to both A IN and B IN rear panel RF jacks.

2.3. RF Connections

The RF jacks on the MPRFA/B RF Detector A/B switch’ front/rear panel are MCX [female]. As an option, the RF jacks on
the rear panel can be F type [female]. There will be six RF connectors at the rear plus one front panel -20 dB test point per

MPRFA/B switch. The front panel test point is –20 dB relative to the RF output. The three connectors on the right side of the
rear panel are the A/B switch connectors (starting from top: A IN, B IN, RF OUT) and the three connectors on the left side of
the rear panel are connectors for the integrated 2-way splitter (starting from top: P2, P1, COM).
