Rack Mount Kit: ST-RMK
Physical Description
The ST-RMK is a rack mount kit that is capable of holding either one or two CEN Ethernet Modules,
SmarTouch STS Expansion Modules, ST-CP Control Processors, or any combination of units in a
single rack space. The front extrusion and bracket are provided to occupy the open bay of the ST-RMK
so that when only one module (or ST-CP) is installed, no gaps are visible in the rack. The front
extrusion and bracket may be installed in either the left or right bay of the ST-RMK. When the
ST-RMK accommodates two modules, the extrusion and bracket are not used.
Items 1 through 6 listed below are the supplied components of the ST-RMK. The tools required for
installation of the ST-RMK are a #1 Phillips 1/4-inch hex bit, a 1/4-inch hex socket, and an inch-pound
torque driver. Follow the installation procedures in the next section.
