Your
HP
3235 mainframe
or
extender can be used on the bench or rack mount-
ed.
You
can
rack mount the frame with either the system side or user side
facing
the
front
of
the rack. Option 908 provides two rack mount kits
for
mounting
the
mainframe
or
extender in a
19
inch wide EIA rack. Provided
are
a
standard rack mount kit
(HP
P/N
5061-9681)
for
mounting the user side
to
the
front
of
the
rack and a reverse rack
mount
kit (HP
P/N
03235-80800)
for
mounting
the
system side facing the
front
of
the
rack. Instructions for installing
the reverse rack mount
kit are contained in
the
section titled "Reverse Rack

The
standard rack mount kit has instructions included with
it.
NOTE
If
you are rack mounting the H P 3235,
we
recommend that you not restrict access
to the rear
of
the rack.
If
service is required
of
modules at the back
of
the rack
where access is restricted, your test system cabling and the need
to
remove the H P
3235 from the rack for service will increase the down time.
If a mainframe
or
extender
is
used on the bench, you must allow for air
clearance around the front, back, and sides
of
the
frame. At least two inches
(50mm)
of
clearance must be allowed
at
the system side
of
the frame, and
one
inch
(25
mm)
of
clearance
at
the user side and frame sides. The fan pressurizes
the cavity
at
the
bottom
of
the frame and forces air through air holes
at
the bot-
tom
of
each plug-in module and system side assembly. Air
is
exhausted through
the front, back, and sides. Restricting the air flow by not allowing adequate
clearance can cause excessive temperature inside the frame. Excessive tempera-
ture reduces reliability
of
both the system assemblies and plug-in modules.
Your
HP 3235
is
equipped with feet and tilt stand in place, ready
for
bench operation.
