Insert the HLC into its card slot.
Ensure that the lower tips of the ejector tabs are positioned properly inside
the front edges of the shelf.

they touch the faceplate.
If you meet with inappropriate resistance, stop and reposition the card.

To cable a single HLC

Plug the 25-Pair Telco connector, P1, of the HomeOffice II Line Card (HLC)
Multi-I/O cable into the connector associated with the slot occupied by the
HLC.

If cable lengths allow, plug the male 25-pin connector, P2, of the HLC
Multi-I/O cable into the MMI terminal.
If the cable is too short, plug P2 into the female 25-pin connector of the
MMI extension cable, and plug the other end of this cable (the male 25-pin
connector) into the MMI terminal.
Note: Obtain the MMI extension cable from your Nortel Networks
distributor by requesting item number A0748519, or you can build this cable
using the pin-out configuration provided on page 47.

If cable lengths allow, plug the female 25-pin connector, P3, of the HLC
Multi-I/O cable into the SDI port on the switch or into the cable kit provided
with the switch.
