Connecting The Icim To Additional Chassis; Icim In And Icim Out Connectors; Icim In And Icim Out Cables - Cisco Prisma II Installation And Operation Manual

Connecting the ICIM to Additional Chassis

The Prisma II platform allows the ICIM2 or ICIM2-XD to be located in one chassis
and control modules located in several other chassis. This communication "daisy-
chain" can be enabled by connecting cables to the ICIM IN and ICIM OUT
connectors located on the connector interface panel of the chassis. This connection is
required if an ICIM2 or ICIM2-XD in one chassis is to communicate with or control
any module located in a separate chassis.
Note: An ICIM2 or ICIM2-XD can control a maximum of 140 modules. Depending
on your application, this is typically 6 or 7 chassis to a rack. Do not exceed these
limits.

ICIM IN and ICIM OUT Connectors

Every Prisma II Standard and II XD Chassis has a DB9 ICIM IN and a DB9 ICIM
OUT connector for the purpose of chassis-to-chassis ICIM connections. ICIM IN is a
female connector and ICIM OUT is a male connector.

ICIM IN and ICIM OUT Cables

The cable required for both ICIM IN and ICIM OUT connections is a shielded 9-
wire serial extension cable, DB9 Female to DB9 Male. This cable can be purchased
locally or from the factory. The chassis data sheet lists the part number for a 6-foot
DB9 Female to DB9 Male serial extension cable. The connectors are a serial 9-pin D-
shell (EIA 574/232).
