Single DPU Configurations
For configurations using a single DPU, setup schemes as described in "Four
Configuration Approaches" still apply. However, the special cabling used in
redundant configurations is of course not needed. This applies to Part No.
04374 and the mix cable adapter. Additionally, special jumper
considerations as listed in "Configuring Local Common I/O" do not apply.
See Figure 10-5.
