Rack Installation & System Setup
The Precis SD Distribution Matrix enclosure can be mounted in a standard EIA 19 in. (48.26 cm) rack.
Rack installation ears are included, and directions for attaching the rack ears are included in the rack
installation instructions (page 18).
Important: The system requires at least one empty rack unit above and below the enclosure to allow
adequate airflow; three empty rack units are recommended.
Required items for rack installation:
Enclosure
Standard EIA 19 in. (48.26 cm) rack
Rack ears (with 8 screws per set)
Screwdriver
Screws that fit your rack for mounting the enclosure(s)
Power cord
Optional items for rack installation:
Surge-protector – highly recommended
A laptop computer or PC with a null modem cable
(for communication with the Precis SD via its CONTROL port)
Installation Recommendations
Write the system’s serial number in an easily accessible location before installing the Precis SD
in a rack. The system’s serial number is located in two places on the enclosure; on the left rear
and on the left side of the enclosure (near the power receptacle).
Use an earth-grounded power cord / system with the Precis SD.
Attach all power cords to a single surge protector and/or an AC line conditioner.
Apply power to the Precis SD enclosure before applying power to the system’s source and
destination devices.
