18-2 SPARC Enterprise M8000/M9000 Servers Service Manual • October 2012
An ACS distributes AC input power from external sources to power supply units (PSUs). If
the dual power feed option is not installed, a main line switch is mounted in an ACS. An
ACS can be duplicated, but active replacement cannot be performed even in such a case.
FIGURE 18-1, FIGURE 18-2, and FIGURE 18-3 show the mounting locations of ACSs in the
cabinets of the M8000 server, the M9000 server (base cabinet), and the M9000 server (with
the expansion cabinet), respectively.
