4.5.3 Main Line Switch Locations
This section describes the locations of main line switch for each type of power
supply. (See
FIGURE 4-4 through FIGURE 4-9)
A power cabinet is required when using the dual power feed option. However, in
the case of the SPARC Enterprise M8000 server single-phase and dual power feed,
the power cabinet is not required because the rack-mountable dual power feed
option is mounted in the SPARC Enterprise M8000 server cabinet (See
FIGURE 4-5).
In the case of the SPARC Enterprise M9000 server single-phase and dual power feed,
main line switches are mounted in both the SPARC Enterprise server cabinet and the
power cabinet (See
FIGURE 4-8).
In the case of the three-phase dual power feed, the main line switch is located in the
power cabinet (See
FIGURE 4-6 and FIGURE 4-9).
