a
power
supply,
complete
the
following
steps:
1.
Read
the
safety
information
that
begins
on
page
v
and
“Installation

Remove
the

blank
from
the
empty
power-supply
bay
by
pinching
the

either
a
power
supply
or
power-supply
blank
installed
for
proper
cooling.
3.
Slide
the
power
supply
into
the
bay
until
the
