1.3 Power Configurations
The ac power distribution within the SH043-series cabinet can be configured in
one of the following three ways to provide the desired level of power redundancy
to the cabinet’s shelf-mounted peripheral devices:
•
Single cabinet power configuration
•
Dual shelf power configuration
•
Dual cabinet power configuration
A description of each configuration option follows.
1.3.1 Single Cabinet Power Configuration
In the single cabinet power configuration, shown in Figure 1–4, a single ac power
source and CDU (A) are used to supply ac power to a single
ac power supply
(A) in each shelf. This is the normal configuration for the cabinet, and it provides
no power redundancy to shelf peripheral devices.
