FatTwin F517H6-FT USER'S MANUAL
Reliable Ground
A reliable ground must be maintained at all times. To ensure this, the rack
itself should be grounded. Particular attention should be given to power supply
connections other than the direct connections to the branch circuit (i.e. the use of
power strips, etc.).
2-5 Rack Mounting Instructions
This section provides information on installing the chassis into a rack unit with the
rails provided. There are a variety of rack units on the market, which may mean that
the assembly procedure will differ slightly from the instructions provided. You should
also refer to the installation instructions that came with the rack unit you are using.
Note: This rail will fi t a rack between 26.5" and 36.4" deep. The SCF418 is not
designed for installation into a Telco post-style rack unit.
Warning: Do not pick up the server with the front handles. They are
designed to pull the system from a rack only.
Stability Hazard: The rack stabilizing mechanism must be in place, or the
rack must be bolted to the fl oor before you slide the unit out for servicing. Failure
to stabilize the rack can cause the rack to tip over.
Identifying the Sections of the Rack Rails
The chassis package includes two rail assemblies in the rack mounting kit. Each
assembly consists of three sections: An inner chassis rail which secures directly to
the chassis, an outer rail that secures to the rack, and a middle rail which extends
from the outer rail. These assemblies are specifi cally designed for the left and right
side of the chassis (see Figure 2-1).
Adjusting the Rails
Each rail assembly has an adjusting screw. loosening this screw allows you to adjust
the length of the rail to fi t a variety of rack sizes.
Locking Tabs
Each inner rail has a locking tab. This tab locks the chassis into place when installed
and pushed fully into the rack. These tabs also lock the chassis in place when fully
extended from the rack. This prevents the server from coming completely out of
the rack when when the chassis is pulled out for servicing.
