Step 1:
Place the system chassis on a sturdy surface.
Step 2:
Using the 9/64” Allen Key provided, unscrew the two screws that 
attach one of the front rubber bumpers to the system enclosure (see 
illustration below). Keep these screws as they will be used to attach 
the new rack mount brackets (see Steps 6-7).
Step 3:
Repeat this procedure to remove the other front rubber bumper.
Step 4:
Remove the two screws that attach one of the rear rubber bumpers to 
the system enclosure (see illustration below):
Note: The SierraFC M164 
is used as an example in 
these illustrations. The steps 
are identical for other 1U systems.
Step 5:
Repeat this procedure to remove the other rear rubber bumper.
Step 6:
Attach one of the brackets (shown below) to the left side of the system 
chassis using the 9/64” Allen Key provided and four of the screws that 
previously attached the rubber bumpers (these are the screws that 
were removed in Steps 2-5). See illustration below.
Step 7:
Attach the other bracket to the right side of the system chassis (using 
the remaining four screws that were removed).
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.

Planning the Installation
Installing the system chassis 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
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), 
/
(
) a d 5/8 ( 5 8
),
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 rack mount brackets supplied use 1.75” spacing.
