Cabling: Line Card Tip and Ring
Installing Network Tip and Ring Connections
Line cards connect to the network through connectors mounted on the back of the
BAC. Each slot has its own 50-pin connector wired to it and is capable of
supporting high-density cards with up to 25 ports.
The network Tip and Ring cables must be equipped with end-fed plug connectors.
Each connector has a captive screw at one end and a tapped hole in the plastic at
the other end. The connector’s captive screw must be replaced with a shorter one
supplied with the chassis. You can attach the cable to the chassis using the cable
ties provided or you can use the locking pivot brackets provided. See Connecting a
Line Card Using Cable Ties or Installing Locking Pivot Brackets on page 3-2.
EMI NOTICE:
In order to maintain compliance with Part 15, FCC Rules and other EMI
requirements, certain line cards require the installation of the supplied
ferrite choke on the 50-pin telephone network cable where it connects to
the BAC. The choke (Part No. 175-0018-0031) and its installation
instructions are provided with the cards.
Before installing the network connectors, the correct slot must be identified. The
connectors are labeled 1–18, from right to left, on the back of the chassis. This
corresponds with the 18 slots for circuit cards. The cable for the first slot is
installed in the connector identified as 1, and so on.
