Installation Instructions
Observe handling precautions: electrostatic-sensitive devices.
To install the additional quad modem card(s)onto the modem carrier
card (see
Figure D-2 ):
1 Find the next available location on the modem carrier card into
which a modem card can be installed.
There are eight locations on the modem carrier card
that can accommodate quad modem cards (up to 32
modems). These locations are numbered (1-4, 5-8, 9-
12, and so on). If, for example, modem cards are
already installed in locations 1-4 through 17-20, the
next available location would be 21-24. It is
important to use the next available location, and not
leave any empty locations.
2 Lower the modem card onto the modem carrier card, keeping the
modem card horizontal.
3 Carefully press the modem card into the card connector, making
sure not to bend or damage any pins. Make sure that the connector
is fully seated.
4 Push one corner of the modem card down onto the nylon standoff
until the locking detent engages.
5 Repeat the previous procedure with the other three corners of the
modem card.
