To Connect Chassis-to-Chassis ICIM IN and ICIM OUT Ports
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 chassis are connected.
4
Connect an ICIM OUT terminator, part number 4013014, to the ICIM OUT
connector on the last chassis in the daisy-chain connection. The ICIM OUT
terminator ships with the ICIM.
Important:
All chassis connected in the daisy-chain must be powered and have a fan tray
installed. A chassis connected in the daisy-chain that is not powered or has no
fan tray installed will cause faulty operation of the ICIM.
All chassis connected in this daisy-chain must have a unique chassis ID number.
If the ICIM OUT terminator that ships with the ICIM is not installed on the last
chassis of a daisy-chain connection, faulty communication with the ICIM may
occur.
