Preface MN/CRS100.IOM

IMPORTANT INFORMATION –

PLEASE READ BEFORE INSTALLATION AND USE

Safety Notices

Electrical Safety

The CRS-100 1:1 Redundancy Switch has been shown to comply with the following
safety standard:

EN 60950: Safety of Information Technology Equipment, including electrical

business machines

The equipment is rated for operation at +12 volts DC and -12 volts DC.
It has a maximum power consumption of 3.2 watts, and draws a
maximum of 160 mA at +12 volts DC and 100 mA at -12 volts DC. The
power supply current is, in all circumstances, supplied by either a single
Comtech CDM-500/550/550T Modem, or a pair of these Modems.

The User should observe the following instructions:

Equipment Connection

The CRS-100 is designed for operation ONLY with Comtech CDM-500, CDM-550 or
CDM-550T Modems. These Modems supply DC operating current (electronically fused
and protected) and control signals for the correct functioning of this unit. Connection to
other manufacturer’s equipment could result in damage to the unit.

Environmental

The CRS-100 must not be operated in an environment where the unit is exposed to
extremes of temperature outside the ambient range 0 to 50C (32 to 122F), precipitation,
condensation, or humid atmospheres above 95% RH, altitudes (un-pressurised) greater
than 2000 metres, excessive dust or vibration, flammable gases, corrosive or explosive
atmospheres.

vi

CRS-100 1:1 Redundancy Switch Revision 2
Preface MN/CRS100.IOM

Operation in vehicles or other transportable installations which are equipped to provide a
stable environment is permitted. If such vehicles do not provide a stable environment,
safety of the equipment to EN60950 may not be guaranteed

Telecommunications Terminal Equipment Directive

In accordance with the Telecommunications Terminal Equipment Directive 91/263/EEC,
this equipment should not be directly connected to the Public Telecommunications
Network.

EMC (Electromagnetic Compatibility)

The CRS-100 1:1 Redundancy Switch has been demonstrated, by independent testing, to
comply with the following standards:

Emissions: EN 55022 Class B - Limits and methods of measurement of radio

interference characteristics of Information Technology Equipment.

FCC Part 15 Class B

Immunity: EN 50082 Part 1 - Generic immunity standard, Part 1: Domestic,

commercial and light industrial environment.

In order that the CRS-100 continues to comply with these standards, observe the
following instructions:

• Connections to the transmit and receive IF ports (BNC female connectors) should
be made using a good quality coaxial cable - for example RG58/U (50 Ω) or
RG59/U (75 Ω).

• All 'D' type connectors attached to the unit must have back-shells which provide
continuous metallic shielding. Cable with a continuous outer shield (either foil or
braid, or both) must be used, and the shield must be bonded to the back-shell.

• The equipment must be operated with its cover on at all times. If it becomes
necessary to remove the cover, the User should ensure that the cover is correctly
re-fitted before normal operation commences.
