RCU101 1:1 Protection Switch Installation
TM055 - Rev. 2.2 Page 2-1
Section 2 - Installation
2.0 Installation Requirements
The RCU101 is designed to be installed within any standard 19-inch equipment cabinet or rack,
and requires 1 rack unit of mounting space (1.75 inches) vertically, and 17-inches of depth.
Including cabling, a minimum of 20-inches of rack depth is required. The unit can be placed on a
table or suitable surface if required.
There are no user-serviceable parts or configuration settings located inside the RCU101
chassis. There is a potential shock hazard internally at the power supply module. DO
NOT open the RCU101
chassis under any circumstances.
Ÿ CAUTION: Before initially applying power to the unit, it is a good idea to disconnect
the transmit output from the operating satellite ground station equipment. This is
especially true if the current RCU101 configuration settings are unknown, where incorrect
setting could disrupt existing communications traffic.
2.1 Unpacking
The RCU101 was carefully packaged to avoid damage and should arrive complete with the
following items for proper installation:
1. RCU101 1:1 Protection Switch
2. One cable set per paragraph 2.3.
3. Installation and Operation Manual.
2.1.1 Removal and Assembly
If using a knife or cutting blade to open the carton, exercise caution to ensure that the blade does
not extend into the carton, but only cuts the tape holding the carton closed. Carefully unpack the
unit and ensure that all of the above items are in the carton. The RCU101 is shipped fully-
assembled and does not require removal of the covers for any purpose in installation.
2.2 Mounting Considerations
When mounted in an equipment rack, adequate ventilation must be provided. The ambient
temperature in the rack should 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.
2.3 Cabling
The RCU101 comes complete with all the cabling required to interface with two Upconverters or
Downconverters. Refer to Figure 2-1 to become familiar with the rear panel connectors on the
RCU101. Figure 2-2 shows a typical interconnection between two Upconverters and the RCU101.
The list of supplied cables is as follows:
