Notes:
1.
Noise
levels
cited
are
for
the
typical
configuration
(A-Frame:
Bulk
Power,
CEC
cage,
battery
option,
media
drawer,
and
two
I/O
drawers).

The
0.6-B
(6-dB)
reduction
in
noise
emission
levels
with
the
acoustical
rear
door
corresponds
to
a
factor
of
4
reduction.
That
is,
the
noise
level
of
a
single
A-Frame
with
Slimline
covers
is
about
the
same
as
the
noise
level
of
four
A-Frames
with
acoustical
covers.
