Connect Multiple Chassis
Introduction
The Prisma II platform allows an ICIM to be located in one chassis to control
application 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.
Note: An ICIM can control a maximum of 82 modules. Depending on your
Note: An ICIM can control a maximum of 82 modules. Depending on your
application, this is typically six or seven chassis to a rack. Do not exceed these limits.
Cabling Requirements
The cable required for both ICIM IN and ICIM OUT connections is a standard “off
the shelf” serial extension cable, DB-9 female to DB-9 male, with connectors that are
a serial 9-pin D-shell (EIA 574/232).
This cable can be purchased at your local computer store or from Cisco. The Cisco
This cable can be purchased at your local computer store or from Cisco. The Cisco
part number for a 6-foot serial extension cable is 180143.
Connecting the Chassis
Follow these steps to make chassis-to-chassis ICIM IN and ICIM OUT connections.
1.
Connect the serial extension cable from the ICIM OUT of the chassis
containing the ICIM to the ICIM IN connector of the second chassis.
2.
Connect a serial extension cable from the ICIM OUT of the second chassis to
the ICIM IN of the third chassis.
3.
Continue this “daisy-chain” connection until all desired chassis are
connected.
Notes:
•
•
All chassis connected in the daisy-chain must be powered and have a fan tray
installed. A chassis that is connected but is either not powered or does not have a
fan tray installed will cause faulty operation of the ICIM.
•
All chassis connected in the daisy-chain must have a unique chassis ID number.
