Adding cards to the System Controller   2–13

This section specifies all jumper and DIP switch settings for all
System Controller cards.

Before adding or replacing any card in the System Controller,
make sure all jumper switches and DIP switches on the new
card are set correctly. You may need to change some settings,
and should check all jumpers and switches to make sure they are
set correctly.

Note that for Quad T1, TX2000, and conference cards, settings are
different depending on whether the card is the first of its type
installed, or is a subsequently installed card of the same type.

The instructions below tell you which jumpers and DIP switches
you need to change, and they specify the correct settings for all
jumpers and switches (including those that do not need to be
changed). This is so you can check all settings and correct them if
necessary.

If you experience a problem with a card, make sure all jumpers
and DIP switches are set as specified here before contacting HNS
for customer support.

The jumper and switch settings indicated in the following sections
have been established for the combination of cards used the
AIReach System Controller. Do not use other settings.

The only option on the Quad T1 card is to set DIP switch S1
(Figure 2-9) to enable or disable H.100 bus termination.
