Hardware installation
To install multiple HLCs
1
Insert each HLC into its card slot.
Ensure that the lower tips of the ejector tabs are positioned properly inside
the front edges of the shelf.
2
Lock the HLC into position by pushing the handles toward one another until
they touch the faceplate.
If you meet with inappropriate resistance, stop and reposition the card. DO
NOT FORCE THE HANDLES INTO POSITION!
See "Self-test" on page 8 for the exact sequence of events that signify a
successful HLC installation.
3
Verify that the switch recognizes the presence of the HLC.
Refer to the documentation specific to your switch for exact procedures.
To cable multiple HLCs
1
For each HLC in your system, plug the 25-Pair Telco connector, P1, of an
HLC Multi-I/O cable into the shelf connector associated with that HLC's
card slot.
Note: This step applies to both IPE modules and Option 11 cabinets.
2
If cable lengths allow, plug the male 25-pin connector, P2, of the HLC Multi-
I/O cable associated with the HLC in the lowest-numbered slot in the daisy
chain into the MMI terminal. Go to step 3.
If the cable is too short, plug P2 into the female 25-pin connector of the
MMI Extension cable and plug this cable's male 25-pin connector into the
MMI terminal.
Obtain the MMI Extension cable from your Nortel Networks distributor by
requesting item number A0748519. Or, you can build the cable using the
pin-out configuration provided on page 47.
Note: See "MMI terminal connection scenarios" on page 49 for optional
methods of establishing the MMI connection for an HLC system.
