Ten blank faceplates and mounting screws are included. These faceplates are
installed over the empty expansion slots and additional faceplates are available
through Crestron’s Customer Support. Four rubber feet (supplied) can be affixed to
the bottom of the CNRACKX-DP to provide stability and to prevent slippage when
mounted on a flat surface. The unit may also be rack mounted by attaching metal
flanges, known as ears (also supplied), to each end.
CNRACKX-DP Ports
There is only one CNRACKX-DP port, labeled COMPUTER, on the front panel.
The other ports on the rear are part of the CNXCPUs.
