WARNINGS AND CAUTIONS PAGE 3
WARNINGS AND CAUTIONS
WARNING
The Power Amplifier Module uses semiconductor devices containing Beryllium
Oxide. Dust from this oxide is toxic and, if inhaled or skin contact is made, can
be hazardous to health.
No danger can arise from normal handling, but no attempt should be made to
break open or tamper with these devices in any way.
These items should not be discarded with industrial or domestic waste.
Caution
During disassembly and assembly, refer to the ‘Torque Settings’ section in this
manual.
Caution
Preparing the radio for alignment will erase from the radio all customer PMR and
Trunking configuration data (channel, signalling information etc). The only data
retained by the Alignment Tool is the factory alignment data for the radio (DAC
settings for TX power, front-end tuning etc).
WARNING
To avoid RF injury, do not touch the Antenna when the Transmitter is in use.
Do not operate transmitter with antenna disconnected – RF burn hazard.
WARNING
The weight of a fully assembled Base Station in the wall mount is approx 10kg.
Two people should be used to lift the unit in this form.
WARNING
When drilling walls, check first for any buried cables or pipes.
WARNING
Disconnect Mains Electricity before working on the unit with wall-mount or rack

1 INTRODUCTION
1.1 GENERAL
Figure 1.1 - Front view of the Xfin Blade.
Brief Description: The Xfin Blade is a 1U trunking system with an integrated basestation
and the capability to provide a control and/or traffic channel. It incorporates the
established MPT1327 trunking standard with next generation hardware and VoIP
technology. A trunked site consists of a number of Blade units which are inter-connected
using standard CAT5 Ethernet cable.

3 DESCRIPTION
The Blade is a 1U high by 19” wide
rack-mountable unit containing two
SRM9000 sub-assemblies, a control
card, and a fan bulkhead which mates
with the angled front panel and MMI
card.
There is also provision for fitting a high
power amplifier or integrated power
supply option.
3.1 VENTILATION
In order to provide full-power
continuous operation in any
orientation and in a 1U envelope, the
Blade uses forced air-cooling. A pair
of fans draws air in from an air intake
located underneath the front lip of
the angled front panel. This air is
compressed by a baffle that directs
the airflow underneath the heatsink
of the SRM9000 sub assemblies. A
second pair of fans is used for the
high-power amplifier option if fitted.
Fans are located to maximise the cooling for the transmitting module. Air is exhausted
through a grilled area on the rear panel immediately below the electrical connectors.
Vent holes in the internal baffle allow a small amount of air to bleed diagonally through the
top section of the chassis to ensure that hot spots do not form on the component side of
the sub-assemblies.
The fans are mounted in a bulkhead located immediately behind the front panel. The front
panel, MMI board and fan bulkhead are separately assembled and removed from the unit
as sub-assemblies.
The fans, loudspeaker and indicator LEDs are all controlled from the MMI PCB that fits
into this sub-assembly. The fans are not only speed controlled to minimise noise and
wear, but their speed is also monitored to provide early warning of failure.
In normal operation, the fans are turned on to full speed to minimise any possibility of a
stall, the speed is then turned down based upon equipment temperature. Even if the
temperature is very low, fans are always kept running at a low speed. Temperature is
sensed from a Thermistor located on the underside of the control board. This Thermistor
protrudes into the airflow from the transmit PA module.
When installing the Blade it is important to ensure that adequate ventilation is provided for
each base station unit. A minimum free-area of 72cm2is recommended per base station at
the inlet AND at the outlet. This should be increased if air has to be drawn through ducts
or has to be deflected around corners.

PAGE 12 DESCRIPTION
Noise and dust build up can be reduced by keeping cabling and other obstructions out of
the main airflows.
There are no dust filters fitted in this product. If it is to be used in very dirty environments,
then additional steps should be taken to prevent ingress of dust as this will affect thermal
performance. Filters should only be used in external cabinets if they can be regularly
maintained.
3.2 SRM9000 SUB-ASSEMBLY
The RF performance of this product is derived from a pair of SRM9000 RF PCBs mounted
on a Heatsink sub-assembly that is designed to permit continuous operation at full power.
The sub-assembly also provides RF screening, so it is important that it is accurately
assembled and reassembled.
The sub-assembly has a plate attached to the rear edge with two quarter-turn fasteners for
rapid removal.
The unit is retained in the Blade chassis by the front edge of the Heatsink that inserts
underneath the fan baffle, the rear of the subassembly is held in place by the quick
release fasteners.
These units are electrically identical to SRM9000 and are also fully interchangeable in the
25W power group (the Transmit module is different for the 100W systems). Control is
provided via the 26-way ribbon connector. Power is supplied via the DB-15 connector and
RF signals are coupled to the BNC sockets with double-screened cables.

DESCRIPTION PAGE 17
Figure 3.3 – View of the Xfin Blade rear panel.
3.5.1 Tx/Rx
The antenna connections on the Blade are provided with 50Ωfemale N-type sockets.
Mating connectors should be galvanically compatible with nickel outer and gold centre pin
to minimise passive inter-modulation.
A minimum of 85dB transmit-receive isolation should be provided by the antenna system
and associated filters.
It is recommended that a good quality flexible co-axial cable is used, e.g. with double-
screening braid and multi-strand copper inner.
3.5.2 Power
This is a D-type housing with 5 stud-pin locations. From left to right (looking at the rear

Notes: 12VDC nominal is normally supplied with 13.6VDC
for battery float charge reasons.
24VDC nominal is normally supplied with 27.3VDC
for battery float charge reasons.
3.5.3 Fuses
Fuse F1 on the fuse-board is a 2A quick-blow, 20 x 5mm component and protects the 12V
line to the MMI PCB.
Fuse F2 on the fuse-board is a 10A quick-blow, 20 x 5mm component and protects the
24V line to the Power Amplifier, if fitted
Fuse F5 on the Xfin Control Card is a 3.15A quick-blow, 20 x 5mm component and
protects the 12V line to the PCB.
In event of failure, the reason for the failure should be investigated prior to replacement.
The fuse should only be replaced with a correctly specified component.
3.5.4 Ethernet
This is a 10/100 base-T RJ45 connection. This is a switch (not a NIC) configuration – care
should be taken to use the correct cable (crossover or straight-through) when connecting
to a network. The use of shielded cables is recommended, especially for VHF installations.
The two indicator LEDs, integrated into the connector, show 100Mbps bandwidth detection
and traffic activity. A third LED, on the Control Card shows if a connection is present.

3.5.7 USB Connector
The IXP420 processor's USB is integrated, USB 1.1-compliant and supports all standard
device requests issued by any USB host controller. It is an USB device-only controller.
The interface supports full-speed operation and 16 endpoints and includes an integrated
transceiver. There are six isochronous endpoints (three input and three output), one
control endpoint, three interrupt endpoints, six bulk endpoints (three input and three
output). The connector is a standard 4-pin socket (pin 1 is the bus voltage rail, 2 & 3 are
the positive and negative signals of the differential USB receiver/driver respectively and
pin 4 is ground).
Note: ensure that the current Blade software supports this interface before attempting to
