Instrument Care and Safety Information
Please read the whole of this section before using your ViaLiteHD product. It contains important safety
information and will enable you to get the most from your Fibre Optic link.
Electrical Safety The ViaLiteHD chassis provides the termination for power inputs and can be fitted with power supplies.
The ViaLiteHD chassis is a Safety Class 1 product (having metal chassis directly connected to earth via the power
supply cable).
When operating the equipment note the following precautions:
Hazardous voltages exist within the equipment.
There are no user serviceable parts inside; the covers MUST NOT be removed.
There are no user replaceable fuses in the chassis mounted equipment. Replacement should only be carried out
by a ViaLite Communications technician.
The chassis earth stud SHOULD be connected to the safety earth.
When using a 2 pin power supply cable the chassis earth stud MUST be connected to the safety earth.
The ViaLiteHD Power Supply Modules do not have an isolating switch on the mains voltage inlet. For this
reason, the ViaLiteHD chassis MUST be installed within easy reach of a clearly labelled dual pole mains
isolation switch, which supplies the equipment.
PSU modules are fused on the mains live feed only. A second fuse should be used for the neutral connection
where the polarity of the connectors can be reversed; rating should match those given in section 5.1.1.
ESD Precautions The ViaLiteHD chassis is not equipped with any active electronics but it may be fitted with them.
Precautions for handling electro-static sensitive devices should be observed when handling all ViaLiteHD modules.
Technicians should ensure that they use effective personal grounding (i.e. ESD wrist strap etc.) when servicing the
equipment. Any equipment or tools used should be grounded to prevent static charge build-up. Good practice should
be observed at all times. For reference see relevant standards.
EN 61340-5-1, “Protection of Electronic Devices from Electrostatic Phenomena – General Requirements”
Optical Safety The ViaLiteHD chassis is not equipped with optical units but it may be fitted with them
The ViaLiteHD RF Transmitter and Transceiver modules contain laser diode sources operating at nominal
wavelengths of 1270nm to 1610nm.
These devices are rated as EN60825-1:2007 CLASS 1 radiation emitting devices. A class 1 laser is safe under all
conditions of normal use.
When operating the equipment note the following precautions:
Never look into the end of an optical fibre directly or by reflection either with the naked eye or through an optical
instrument.
Never leave equipment with radiating bare fibres –always cap the connectors.
Do not remove equipment external covers when operating.
Hot surface The ViaLiteHD Redundancy load module may have hot surfaces when operating under fulll load. The hot surfaces are
not accessible when fitted in an approved chassis installation.
Suitable precaution should be taken when handling this device.
Allow to cool for 10 minutes
Do not touch metallic surfaces or printed circuit board when hot.
When handling, hold front panel and handle only.

1 Initial Inspection
Unpack and inspect the equipment as soon as possible. If there is any sign of damage or any parts missing, do not install the equipment
before seeking advice from ViaLite Communications or your local agent.
The equipment received should match the delivery note that is shipped with the equipment. If there are any discrepancies, contact ViaLite
Communications or your local agent.
2 Introduction to the ViaLiteHD Range
The ViaLiteHD range has been developed to provide a modular solution to the transmission of a wide range of analogue and digital data
where traditional ‘copper wire’ systems cannot be used, for example, in electrically noisy environments or over long distances.
The range is ideal for permanent and semi-permanent installation in Satellite communications, GPS, antenna remoting and other related
applications.
The variety of links available includes low frequency timing (2kHz) to wideband RF (4.2GHz), RF splitters, amplifiers and switches; they also
include a full suite of supporting functions including RS232/422/485, Ethernet and control systems to monitor and control the system with
both Web and SNMP interfaces.
All ViaLiteHD equipment operates over high quality glass fibre optic cable, which can be supplied in low-cost 3mm jacket, riser and outdoor
specifications. The links can also be used with existing cable systems at customer premises.
A ViaLiteHD system can be added to at any time, enabling the system to evolve with the needs of the user.
ViaLiteHD is a product brand manufactured by Pulse Power and Measurement Ltd (PPM). ViaLite Communications is a division of Pulse
Power and Measurement Ltd (PPM).

3 ViaLiteHD and ViaLite Classic compatibility
The RF and optical interfaces of most ViaLiteHD and ViaLite Classic modules are compatible. However the physical size, mounting
systems and control of the modules are different, so it will not be possible to fit ViaLiteHD module in a ViaLite Classic chassis or housing and
vice versa. However it is possible for modules of different types to interwork and be used to expand existing systems. Listed below is a brief
summary of inter family compatibility.
RF Compatible optical and RF interfaces
RF + digital Compatible optical and RF interfaces
RS232 Compatible optical and digital interfaces
RS422 Compatible optical and digital interfaces
RS485 Compatible optical and digital interfaces
Ethernet Modules of matching speed have compatible optical and digital interfaces
Redundancy Switch Compatible RF interfaces may need interface cable (no optical interface)
RF Splitters Compatible RF interfaces (no optical interface)
Amplifier Compatible RF interfaces (no optical interface)
SNMP Not compatible

4 ViaLiteHD System Components
4.1 ViaLiteHD 19” chassis
4.2 Description
The 19” chassis is suitable for 19” rack mounting. There are two versions, one for alternating current (AC) power and one for direct current
(DC) power.
The chassis accommodates up to thirteen (5HP) plug-in RF/data modules, one (7HP) control module and two (6HP) plug-in power supplies.
The hot-swappable, dual power supply capability provides full redundancy and maximum reliability to avoid traffic loss in the event of a power
supply failure. The chassis incorporates a backplane PCB for the distribution of DC power, status alarms and data.
Note: Each power supply position requires a separate power source to provide fully redundant protection.
The plug-in modules simply plug into the chassis, allowing the user to replace modules quickly and easily or to upgrade the system with
additional modules at any time. For ease of upgrade and replacement, most modules are offered with the option of a Blindmate interface,
where all interface cables are connected to in the chassis hardware and not the module.
Each of the RF/data module positions has a dedicated D type connector that provides access to all the digital data for that module; this is
fitted to the chassis backplane.
All of the module alarm outputs, both digital alarms and analogue monitors, are routed to a SCSI-3 connector on the rear panel of the
chassis. This connector also has the interface for the summary alarm relay if a module has been fitted to provide this function. This permits
the integration of the ViaLiteHD equipment into a Maintenance & Control system.
All of the module external power connections (LNA feeds) and chassis backplane external power connections are routed to a second SCSI-3
connector on the rear panel of the chassis.
Module slots 1-14 have a data bus that can be used for sending and receiving data between modules.
4.3 Power Interface Management
External power can be provided to, or taken from the chassis via the “Power Concentrator” connector J4, the current should be limited to 1A
per pin for single pins or 0.8A per pin for shared pins. The power level (sum of chassis and external power) must be within the capability of
the chassis power supplies, see specification in section 5.2.
4.3.1 External backplane power
If the chassis is powered externally the input DC voltage measured at the power concentrator connector should be 12Vdc +/- 0.5V. If chassis
power supplies are also fitted we would advise that a low voltage drop diode (i.e. Schottky or similar) be used to OR the power feeds.
It is also possible to provide external power to a chassis fitted with PSUs, for this reason the current share bus (CSB) is available on “Power
Concentrator” connector J4. If this option is used the chassis must be interfaced to ViaLite Communications approved external power
supplies, and the +12Vdc, GND and CSB lines for each power source should be connected in parallel.

4.3.2 Module bias feed
It is possible to provide a bias voltage from the modules to connected devices. Dependent on module type, this can be either internally
sourced from the module or provided via the “Power Concentrator” connector J4. The current limit is dependent on module type fitted.
4.4 Alarm Management
The alarm strategy on the ViaLiteHD system caters for all levels of Alarm and Monitoring System complexity from simple module failure LED
indication, to local and remote end alarm notification and redundancy switching.
All modules provide an alarm output to the chassis backplane to indicate that the module is present and working correctly. The alarm is fail-
safe in that when a working module is withdrawn from the chassis an alarm is registered for that module position.
4.4.1 “Alarm Concentrator” 50way Connector J1
All module alarms are provided for the user on the 50 way “Alarm Concentrator” connector on the chassis rear panel. These outputs are
"open collector" outputs. There are also two analogue monitors per module position. Their function depends on the type of module fitted.
4.4.2 Connecting to an "open collector" output.
The alarm output pin should be connected to a suitable current source (a positive voltage via a 10kohm pull-up resistor is adequate). When
the module is in a working (non-alarm) state, the alarm output pin is short circuited to ground by the module. If the module enters an alarm
state, the alarm pin is released to a high impedance state and current is no longer drawn from the constant current source. In the case of a
positive voltage and pull-up resistor, the voltage on the alarm output pin will rise to indicate the alarm state. It follows that, if a module is
removed from the chassis, the alarm will be raised for that module position.
The capability of the open collector is dependent on the module that provides it.
The typical capability of the Open Collector/Drain is 50mA maximum current sink and 15V maximum voltage (Vext)
4.4.3 Summary Alarm
A summary alarm can be provided if an appropriate module is fitted in the 7HP slot (slot 14). This function can be provided by either of the
following modules
SNMP control module (automatic sensing of module presence)
Summary alarm relay module (manual setting of module presence)
If no module is fitted the summary alarm relay connections will all be open circuit.
If an appropriate module is fitted there is a volt free 3-pin connection present on “Power Concentrator” Connector J4. The three connections
are Normally Open (NO), Common (COM) and Normally Closed (NC).
Condition 1 - Power applied to chassis, no alarms (i.e. normal condition)
Pin NO is open circuit
Pin NC is connected to COM
Condition 2 - Power removed from chassis and/or one or more module alarms (i.e. Alarm condition)
Pin NO is connected to COM
Pin NC is open circuit

4.4.4 Module Alarm Defeat
In some installations, the chassis might not be fully populated with modules. In this case, the module alarm output for the vacant positions
would register a continuous alarm state and the Summary Alarm Output would also register an alarm condition.
It is very important to ensure that the DIP switches on the Summary alarm relay module or software alarm mask of the SNMP control module
for chassis positions where modules are “present” is set correctly. If a DIP switches/software mask is set incorrectly for a “present” module,
then if this module were to fail, NEITHER THE MODULE ALARM NOR THE SUMMARY ALARM WOULD DETECT THE FAILURE. The
front panel LEDs of the module will always register an alarm condition correctly regardless of the state of the DIP switches/software mask.
4.4.5 Using open collector alarms with controller cards
When a chassis is fitted with a controller card (i.e. SNMP and web controller or summary alarm card) all the alarm lines will be loaded and
pulled up. The alarm lines are pulled up to as shown below.
SNMP and web controller pulled up to 3.3V via 4.7k ohms* (see warning below)
Summary Alarm pulled up to 5V via 100k ohm, with series diode
* Applying external voltage to these pins may cause damage, contact ViaLite communications
Note: the alarm line for slot 14 is always pulled up irrespective of the card status, these cards are all fitted with summary alarm relays.
4.4.6 Using open collector alarms with RF switch and RF splitter cards
When a chassis is fitted with an RF switch or RF splitter card the alarm lines of the adjacent slots will be loaded and pulled up. The alarm
lines are pulled up to as shown below.
RF switch or RF splitter pulled up to 5V via 10k ohm, with series diode
4.5 Heat management
The chassis is designed to meet its environmental specification, when operating in a typical configuration. A typical configuration is all
modules populated (13*Transceiver, 1*SNMP, 2*PSU), chassis power consumption 67 watts, no external DC power input or DC output and
no obstruction to convection air path.
Under normal operating conditions module slots 1-14 are cooled by convection, module slots 15 and 16 are force air cooled with exhaust at
rear of the chassis. The chassis will continue to run without the forced cooling provided by the integrated fan but its operating temperature
will be reduced.
Single PSU only fitted: maximum operating temperature reduced by -5C
Airflow above chassis blocked: maximum operating temperature reduced by -10C
Airflow below chassis blocked: maximum operating temperature reduced by -5C
No forced air: maximum operating temperature reduced by -10C
Also see section 5.2 that details the typical power consumption of most common types of modules.
4.6 Unused module positions
We advised that all unused slots be fitted with blanking panels. Different widths of blanking panel are available these fit the 5HP general
purpose (slots 1-13), 7HP controller card slots (slot 14), 6HP power supply slots (slots 15,16). They can be used with any ViaLiteHD 19inch
chassis and will prevent accidental/unwanted access and the ingress of dust. Blanking panels available are.
85044 ViaLiteHD Blank Panel, 5HP Slots 1-13
85050 Reusable ViaLiteHD Blank Panel, 5HP Slots 1-13
HPS-0 ViaLiteHD Blank Panel, 6HP Slot 15, 16
85046 ViaLiteHD Blank Panel, 7HP Slot 14
85049 Reusable ViaLiteHD Blank Panel, 7HP Slot 14
Contact ViaLite Communications or your local agent for more details.
There are two types of the 5 and 7 HP blanking panels. The standard blanking panels are fitted with snap in plastic barbs. These are
designed to permanently hold the blanking panel in position. Please ensure that you have fully planned the configuration of your chassis, as
the plastic barbs are a close tolerance fit and removal results in the barbs being broken; the panel should then be discarded.

There are also reusable panels available (85049 and 85050) with handles to keep them in place.
The 6 HP blanking panels are fitted with handles to secure them into either slot 15 or 16. These are design to permanently hold the blanking
panel in position.

4.7 Minimum power supply load
If the chassis power supplies are operating in dual redundant configuration, there should be a minimum load of 12 watts to ensure that both
power supplies are active, below this level one power supply may be in idle mode (its LED will not be illuminated). If necessary a
redundancy load module can be supplied, to fit into any unused slots to meet this minimum power requirement, see section 5.3.
