The
UEPO
switch
disables
350
V
bulk
power
conversion
and
isolates
all
battery
power
to
the
battery
compartments,
without
having
to
disconnect
the
heavy
power
cords
under
the
customer’s
raised
floor.
At
the
system
level,
the
UEPO
switch
is
connected
to
each
of
the
two
BPCs
through
two
interface
connectors.
The
switch
can
be
concurrently
replaced
by
forcing
the
BPCs
into
UEPO
bypass
mode,
using
the
small
slide
switches
on
the
face
of
the
BPCs.
The
switch
is
mounted
in
the
side
area
of
the
rack
and
remains
stationary
when
the
front
cover
of
the
system
is
opened.
The
service
buttons
are
used
by
service
personnel
to
repair
the
power
subsystem.
If
the
system
is
off
when
the
service
complete
button
is
pressed,
the
system
will
power
on.
A
sliding
plastic
cover
over
the
red
switch
prevents
it
from
being
accidentally
activated
in
the
customer
environment.
