Connecting the AIC Network Module to the Network
The AIC network module is connected to the network using four high-density SCSI-type connectors on
the front panel.

Connecting the AIC Network Module to the Network
An AIC network module provides four 50-pin receptacles. Use cables that have male Micro DB-50
connectors at both ends with all conductors straight-wired. Central office equipment is cabled to the
patch panel, and then cross-connected to the AIC cable.
Two different patch panels can be used. The AIC-1 patch panel terminates one AIC and has voltage
terminations with lugs and fuses for voltage monitoring. The AIC-2 patch panel terminates up to two
AICs or 128 contact closure points
See
See the AIC data sheet on www.cisco.com for recommended patch panel and cable vendors.
Damage to the AIC network module can occur if an alarm set for monitoring current is connected to
Caution
a sensor for monitoring voltage. Make sure that your alarms are connected to the proper sensors.
Connect the cable to the AIC before connecting it to the patch panel or other connection. Otherwise,
Caution
voltage could be present on the male pins that connect to the AIC.
Caution The signal I/O connections on this unit are intended only for connection to NEC/CEC Class 2 or
equivalent circuit. This means that the voltages applied to I/O connections should not exceed
42.4 Vpk or 60 Vdc and it should be a limited/fused power source. For more details on Class 2
circuits, refer to the National Electrical Code/Canadian Electrical Code. This does not apply to the
analog input/output terminal strip numbers 1–8 on the AIC-1 patch panel.
This unit is not intended for connection to exposed plant leads. Therefore, it should not be connected
Caution
to circuit conductors that extend beyond one building and are run so as to be subject to accidental
contact with AC main conductors, or are exposed to lightning on interbuilding circuits on the same
premises.
Ports are numbered from right to left and from bottom to top, as labeled on the module rear panel.
