Power Distribution
6–4 UltraSCSI RAID Enclosure
AC Input Power Controller
The ac power distribution is through the power controller (see Figure 6–2)
to the shelf power supplies. The O
N
–O
FF
switch on each power controller
controls the ac distribution to the associated power bus (A or B). These
power controllers are completely interchangeable and there are no physical
or electrical differences between them. These units do not have any error
indicators nor do they generate any error signals. In a standard or redundant
power supply configuration without an optional second power controller, a
power controller failure disables the enclosure.
