Installing and cabling a single HLC

Introduction
Preparing the switch and actually placing the HLCs into their slots are identical
procedures, no matter how many HLCs there are in your system. However,
cabling is different for one-, two-, and more than two-HLC systems.
In all systems, the switch's SDI connection is provided by either a 25-pin male
SDI port or a cable kit with a 25-pin male connection. Establish your system's
SDI link by attaching P3 of the HomeOffice Line Card (HLC) Multi-I/O cable,
or the female 25-pin connector of the SDI extension cable to the switch's SDI
connection.
For details on the potential methods of connecting to an MMI terminal, see
"MMI terminal connection scenarios" on page 49.
This topic explains how to install and cable one HLC in a single-card system.
Refer to the illustration on page 27 for help in making the proper connections. If
you are installing multiple HLCs, see "Installing and cabling multiple HLCs" on
page 53.
To prepare for installation
1 Configure the slot into which the HLC is to be inserted as if it were to hold
an extended digital line card (XDLC). Refer to the documentation specific to
your switch for the exact procedures.
2 Set the DIP switches for the appropriate HLC configuration. See
"Understanding the DIP switches" on page 33.
