RCS20 M:N Redundancy Switch
Installation
2.3
Removal and Assembly
Carefully unpack the unit and ensure that all of the above items are in the carton. If the available
AC mains power at the installation site requires a different cordset from those included in the
package, then a suitable and approved cordset (for the country where the equipment is to be
installed) will be required before proceeding with the installation.
Should the Power Cable/AC Connector be of the wrong type for the installation, either the cable
or the power connector end should be replaced. The power supply itself is designed for universal
AC application. See specifications for appropriate voltages and currents.
2.4
Mounting Considerations
Adequate site planning and preparation simplifies the installation process and results in a more
reliable system. The user should ensure that the site has adequate electrical power. The power
sources should be properly grounded and as free as possible from electrical interference. If a
redundant configuration is to be used, then each power cord on the RCS20 must be plugged into
its own separate power circuit. Each circuit must have its own independent circuit breaker.
Grounding is achieved automatically when the three-prong power plug is inserted into a power
receptacle. Verify by testing that there is no voltage present between the chassis of the Switch and
the power line ground.
The protective ground must not be bypassed with a three prong to two-prong
adapter or defeated in any way. Defeating the ground may result in operator
injury or damage to the system.
When mounting The RCS20 in an equipment rack, adequate ventilation must be provided. The
ambient temperature in the rack should preferably be between 10° and 35°C, and held constant
for best equipment operation. The air available to the rack should be clean and relatively dry. The
units should not be placed immediately above a high-heat or EMF Generator to ensure the output
signal integrity and proper receive operation.
The RCS20 is designed so that it can be mounted in a standard 19-inch rack. The RCS20 is 5¼",
3 Rack Units (3RU) high and must be mounted on the front of a rack with the front panel facing
forward
The DDS20 is 8¾" (5RU) high and is preferably mounted at the top of a rack unit with the
Terrestrial Interface connectors available at the top of the rack and the modem connections
available at the at the bottom of the DDU20 in the interior of the rack. The DDS20 may also be
mounted at the rear of a rack with the Terrestrial Interface connectors available at the rear of the
rack and the modem connections available in the interior of the rack.
The IFS20A is also 8¾" (5 RU) high and is designed to be mounted at the rear of a rack with the
Up/Downconverter interface connections facing to the rear of the rack with the modem IF
connections available in the interior of the rack. The IFS20A may also be mounted in the top of a
rack with the Up/Downconverter interface connections available at the top of the rack and the
modem IF connections available inside the rack.
