23 Inch Mounting
For 23 inch mounting, the short side of
the mounting brackets is attached to
the side of the shelf. There are three
positions to mount the brackets on the
shelf. Choose a suitable mounting
position for the shelf then, using the
provided 10-32 screws and lock
washers, attach the bracket to each
side of the shelf. Place the shelf in
position on the rack and, using the
appropriate screws and lock washers,
attach the shelf to the rack. Please
note the hardware (screws) required to
mount the shelf to the rack is not
supplied with the 2745 shelf mounting
kit.
Cabling Overview
New Installations
The 2745 Shelf cabling configurations will vary depending on installation locations and the number of lines
supported by the DSLAM. However, the physical interface to the rear panel connectors is standard 50-pin RJ-21
type receptacle connectors. Each splitter card uses 24 pairs of the 25 pairs available on each 50-pin connector.
After the shelf has been attached to the rack, the cabling can be prepared as shown below
For improved DSL performance, Comtest recommends the use of CAT 5, or better, cabling on the DSL connectors
for our 2745 Power Combiner Shelf in order to ensure that optimum system performance is achieved and
maintained. Comtest suggest that the CAT 5 mating connectors used be equipped with either a 90
so that routing of the cables is simplified.
CAUTION - To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord/cable.
Install the cables in the following sequence:
Connect xDSL Cable first
Insert the screw through the connector
cover and into the RJ-21 connector, on
the back panel, and carefully tighten.
Connect SPAN Cable second
Assemble the connector cover and plug
as above.
