B.17 AC Section
AC section (ACS) is positioned at the input side of the power supply unit (PSU), to
protect the system from electromagnetic interference (EMI).
There are two types of ACS, ACS for M8000 and ACS for M9000. Both single-phase
AC and three-phase AC types are available for both types.
ACS consists of a terminal strip for power input, a main line switch, and so on.
Among the ACS, ACS_D is a unit for supplying the internal current to the three-
phase power feed cabinet, which doesn't have a main line switch and the external
connection.

■ The ACS_A is a single-phase power feed unit for the SPARC Enterprise M8000
server. This unit uses three power cords to receive power and distribute AC
power to nine PSUs.
