Installing RS-232 cables

Introduction

You need two I/O-to-backplane cables (NT6P0123 or

NT6P0114), one 5-port fanout cable (NT6P0109), and one

4-port fanout cable (NT6P0110) for each module, except for the

last module in a 5-node shadowed system that does not use the

4-port cable. Refer to “Intermodule cabling for a two-module

system” on page 9-13.
