Constructing the Main Distribution Frame (MDF)
The Main Distribution Frame (MDF) has two different standard quick-connect
terminal blocks that are mounted on a 3/4-inch plywood backboard. Mounting
these blocks on standoffs for ease of access is recommended. The
recommended blocks are 66B50 for termination of the MDF Cable Assembly
and 66M50 for termination of the station cables.
The Intermediate Distribution Frame (IDF) requires the 66M50 blocks only.
Both the MDF and the IDF use standard bridging clips for each terminal block.
The bridging clips mate the left half of the terminal block (terminated cable
run) to the right half of the terminal block (cross connection wire) to the
terminal block (cross connection wire). The bridging clips are also useful
during troubleshooting to help isolate the cable runs and terminals/telephones
from the central equipment and the Central Office Network from the system.
The SV8100 system can be floor-mounted, wall-mounted, desk-mounted or
rack mounted. Plywood should first be installed on the wall where the chassis
will be positioned, to allow for secure anchoring. It is equipped with a bracket,
which can be used to secure each chassis in any of these installations.
Ensure that enough space is available to allow the installation of the additional
chassis above and below the Controlling Chassis.
The system requires a 3-prong dedicated 110 VAC 60 Hz circuit (NEMA 5-15
receptacle) located within 7 feet of the AC receptacle. Telco should install the
RJ21X to the right of the Controlling Chassis. Extension blocks should be
installed to the left of the Controlling Chassis.
The chassis is shipped fully assembled. The following are shipped with the
chassis:
1 black 3-prong power cord (packed outside the chassis)
