Teledyne LeCroy SierraFC M8-4 Rackmount Installation Guide - Manual (Page 2)

Take the following steps to attach the two L brackets to the system chassis:
Step 1: Place the system chassis on a sturdy surface.
Step 2: Using the Allen Key, unscrew the two screws that attach one of the
front rubber feet to the system enclosure (see illustration below). Keep
these screws as they will be used to attach the new L brackets (see
Step 4).
Step 3: Repeat this procedure to remove the other front rubber foot.
Step 4: Attach one of the L brackets (shown below) to the left side of the
system chassis using the Allen Key and two of the screws that
previously attached the rubber feet (these are the screws that were
removed in Step 2). See illustration below.
Planning the Installation
4
Installing the system chassi in a rack mount enclosure requires some planning for
issues such as location, spacing, airflow and power supply. These issues are
reviewed below.
Location
Most rack mounts conform to the
EIA 310-D (RETMA) standard,
which provides mounting holes on
two vertical support rails which are
separated by 19” (480 mm). This
standard provides separation of the
spacing holes in increments of both
1/2” (12.7 mm) and 5/8” (15.8 mm),
which allows for various multiples
of these spacing distances (such
as 1.75” - 44.5 mm - which is
obtained by the separation of two 5/8” gaps and one 1/2” gap). See the diagram
on the right. The L brackets supplied use 1.75” spacing.
Step 5: Attach the other L bracket to the right side of the system chassis (using
the remaining two screws that were removed in Step 3).
Step 6: Remove both rubber feet on the rear of the chassis, again using the
Allen Key.
Note: Store the four rubber feet removed from the system in case you would
like to return the system to the original configuration at a later time.
