Do not connect a
T1K-05CBL-LL to the
left side of the local
I/O base.
A power supply cannot
be used on a base that is
connected to a system by
a T1K-05CBL-RR-1.
System shown above:
The first power supply powers the CPU and the two I/O modules to
its right. The second power supply powers the two modules to its right and the three I/O
modules on the first local expansion base. When a T1K-05CBL-RR-1 is used, the expansion
I/O assignments are from right to left (reversed). A power supply cannot be used on a base
that is connected to a system by a T1K-05CBL-RR-1. Power Supply #3 powers the three
I/O modules to its right on the second local expansion base. This is only an example and the
power budget requirements vary depending on the I/O modules used.
