on
when
a
second
power
supply
installed
or
when
one
of
two
power
supplies
present
in
the
system
is
replaced.
To
install
a
second
power
supply,
or
to
replace
a
failing
power
supply
when
two
are
present
in
the
system,
do
the
following:
1.
If
a
failing
power
supply
is
present,
disconnect
the
power
cable
from
the
failing
power
supply
at
the
rear
of
the
system.
2.
Place
the
system
into
the
service
position
as
described
in
“Placing
the
Model
275
into
the
Service
and
Operating
Position”
on
page
248.
3.
Remove
the
service
access
cover
as
described
in
“Removing
the
Service
Access
Cover”
on
page
249..
4.
Ensure

supply
bay
is

by
doing
one
of
the
following:

then
up
and
out
of

power
supply
by
doing
the

1)
Remove
the
power
cable
from
the

of
the

handles,
and
press
the
retractable
spring-activated
portion
of
each
handle.
This
action
releases
the
spring
latch
located
on
the
bottom
side
of

release
handles

degrees)
to
the

By
placing
the

perpendicular
to
the

of
the
power

the
base
or
hinged
portion
of
each
handle
acts
as
a
cam
and
helps
pry
the
power

from
its
connector
located

handles
located
on

of
the

power
supply.
Pivot
the
power

handles
upward
to

degrees.
This
action
puts
the
handle
cams
into
the
correct
position
to
help
seat
the
power
supply
into
its
connector.
6.
Carefully
insert
the
new
power
supply
into
the
power
supply
bay.

the
power
supply
handles,
carefully
pressing
the
power
supply
into
the
connector.
The
spring
latch
located
on
the
underside
of
each
handle
will
snap
into
place,
indicating
that
the
power
supply
is
seated
correctly
and
