I/O Interface
Section 10A
10A-49
You can place several 1746I modules with 1746 I/O chassis in the 9/Series
fiber-optic ring. Each 1746 I/O chassis must contain its own 1746I module
(daisy chaining racks together using one 1746I module is not allowed).
The number of I/O points/chassis is limited to the number of ASRN chips
supported by the 9/Series fiber--optic ring. Use page 10B-10 to calculate
how many ASRN chips are required for each I/O chassis. A maximum of
16 chassis are allowed on the 9/Series fiber-optic I/O ring.

1746 Series B I/O Chassis
Three different fully equipped 1746 I/O chassis are available for the
9/Series I/O ring. These chassis contain the following I/O devices:
