IF you are cabling
more than two HLCs
together
4 If you are cabling the HLC occupying the card slot with the highest number
in the daisy chain, connect the female 25-pin connector, P3, of its
Meridian HomeOffice II Line Card Multi-I/O cable to the SDI port on the
switch.
If the cable is too short, plug P3 into the male 25-pin connector of the SDI
extension cable.
Note: Obtain the SDI extension cable from your Nortel Networks distributor
by requesting item number A0748520, or you may build the cable using the
pin-out configuration provided on page 48.
To verify the installation
1 Log in to the HLC using the procedure for logging in to daisy-chained
installations. See "LOGIN (L)" on page 91.
Result: A successful installation produces a system prompt in the following
format: "HLCXX," where "XX" is the daisy-chain address of the active card.
If the proper daisy-chain address does not appear in the system prompt,
log out of the system and check the card for proper DIP switch 1 (SW1)
address configuration. Pay close attention to the settings for positions 7 and
8 (MMI end and SDI end).
If the proper daisy-chain address still does not appear in the system
prompt, log out of the system and check for proper cabling connections.
2 Repeat step 1 for every HLC in the daisy chain.
If there are cards for which the proper daisy-chain address did not appear
after confirming proper daisy-chain address settings and cabling
connections, contact technical support.

THEN
plug P3 of this HLC's Multi-I/O cable into P2
of the HLC Multi-I/O cable for the next HLC in
the daisy chain.
If the next HLC is occupying the highest-
numbered slot in the daisy chain, go to step 4.
Otherwise, repeat this step until all
intermediate HLCs are cabled together.
