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.
2.3 Rack Mounting
To allow for the easy installation of cables and adequate air circulation through the units, a
minimum of six inches of clearance must be provided at the sides and rear of the units. In addition,
the RCS10 requires a minimum of 1-3/4 inches (1U) of clearance at the top of the unit.
The RCS10, when fully populated, weighs approximately 100 lbs. When installing into a rack
enclosure, a minimum of two technicians are required to minimize personal hazard.
2.3.1 DMD10 (Modem) Installation into the RCS10 Chassis
The RCS10 is shipped with the Modems (DMD10s) and External Reference Card packaged
separately for shipping purposes. All modems are universal and may be installed into any slot (1-9).
The External Reference Card is installed in slot 10.
2.4 Configuring the system
If either AC line cord remains connected to the RCS10, dangerous AC voltages will be present
within the unit and the cooling fans will also be operational. Although AC power is not present on
the backplane, care must be taken when installing or removing a plug-in module since DC voltages
will be present.
Before powering up the RCS10 or attaching cables to J12 (Sync Data RS422/RS485/V.35), the
following steps MUST be verified in order to avoid damage to the equipment. Ensure the following:
1. The cables must be wired correctly. Refer to Table 2-1, J12 Sync Data,
RS422/RS485/V.35;
2. The External Interface is programmed or supports the appropriate Interface type: RS232,
RS422, or V.35;
3. The Universal Interface Module (UIM) is configured for the appropriate Interface type:
RS232, RS422 or V.35.
