Connection Instructions
Before starting, refer to the installation plan to determine the cables intended for
connection to the D8E1T1 module.
• Connect the standard interface cable (CBL-DXC100-D8E1T1/BAL, or cross-
cable CBL-DXC100-D8E1T1/BAL/X, or equivalent) to connector P1 on the
panel of the interface module and each
RJ-45 connector to the user’s equipment.
• When the optional N+1 redundancy function is implemented, connect a
CBL-100PSX-D8E1T1 cable from connector P1 of the module to the
corresponding PSX interface module.
A single screw is used to attach one end of the RJ-48M plug to the module
connector standoffs on the rear interface module.
In order to securely fasten the opposite end of the plug, cable tie mounts have
been provided on the rear interface module. These mounts are located above and
below the RJ-48M connector so that tie-wraps (provided) can be used to securely
hold the plug in the connector:
• The cable tie mount above the connector is used to attach a tie-wrap around
an interface cable (CBL-100PSX-D8E1T1) that feeds down from the
DXC-100PSX N+1 Protection Switch.
