I/O
Subsystem
Features
I/O
subsystems
have
two
redundant
power
supplies.
One
of
these
power
supplies
is
capable
of
providing
the
necessary
voltages
and
currents,
independent
of
the
other
power
supply.
The
left
and
right
power-supply
output
voltages
are
connected
and
monitored
by
the
power
distribution
board
contained
in
the
I/O
subsystem.
The
left
and
right
power
supplies
are
hot-pluggable
and
may
be
changed
one
at
a
time
while
the
system
is
operational.
Each
power
supply
provides
5V
dc,
3.3V
dc,
12V
dc,
and
5V
dc
standby.
