Quad Modem Card Installation Instructions

Observe handling precautions: electrostatic-sensitive devices.
To install the additional quad modem card(s)onto the Modem Module
(see Figure C-2):
1 Find the next available location on the Modem Module into which a
modem card can be installed.
There are eight locations on the Modem Module
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 Insert the four nylon standoffs into their respective holes on the
Modem Module.
3 Lower thequad modem card onto the Modem Module, keeping the
quad modem card horizontal.
4 Carefully press the quad modem card into the card connector,
making sure not to bend or damage any pins. Make sure that the
connector is fully seated.
5 Push one corner of the modem card down onto the nylon standoff
until the locking detent engages.
6 Repeat the previous procedure with the other three corners of the
modem card.
7 Follow the installation instructions detailed in Chapter 2 to reinstall
the upgraded Remote Annex 5393/PRI into the System 5000 Hub.
