Installing the Other Plug-In Cards System Installation
3.8.5 User Cards
The system also has numerous user cards for connections to voice and data circuits at the CPE,
and alarm cards for system alarm reporting to/from external facilities. The user cards go in
slots U1 to U8 of the two-sided chassis and front-loading chassis with power supplies on top.
Or, they go in slots P1 to P4 and W1 to W4 of the front-loading chassis with power supplies
on the side.
You can install up to seven user cards into a front-loading chassis with power supplies on the
side. If you have this chassis type, you must reserve one of the “W” or “P” slots for either a
WAN card or a server card.
3.8.6 Connecting Cables to the Cards
After inserting the cards into the system chassis, connect them to the external equipment,
using the proper cables. The cards have various types of connectors on their faceplate for those
connections.
Some cards have 50-pin Amphenol-type jacks on their faceplate. To connect a cable to this
type of jack, first plug the male connector of the cable into the jack and push it in all the way.
Then, tighten the mounting screws above and below the cable connector.
For modular (RJ-11 and RJ-48) jacks, push the cable’s mating plug into the jack until it snaps
into place. However, do not try to force the plug into the jack.
For DB-9 and DB-25 jacks, first plug the cable’s mating connector firmly into the jack. Then,
thread the screws on either side of the cable connector into the standoffs above and below the
card jacks, and hand-tighten them.
Refer to the individual card chapters in this guide for more information on the associated card
jacks and signal pinouts.
