is included with some systems, or may be purchased 
as an accessory for existing systems.
Two brackets, which are attached (as shown in this 
document) to the side of the chassis, connect the 
chassis to the mounting posts of the rack. 
Some racks provide a power strip along the length 
of one of the rear posts. If your rack has this feature, 
the systems and the rack mounting brackets are 
designed so that power can be supplied to the rear of the unit while network cables 
and user control is available at the front (exposed) portion of the system.
Rack Mount Kits covered by this document include kits for the Sierra™ M124, 
SierraNet™ M408 and SierraFC™ M164.
