18-2 SPARC Enterprise M8000/M9000 Servers Service Manual • June 2010
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 CMUs.
