Rack rails
The T640 is a rack-capable tower server. When the customers select rack mode chassis, T640 will support the optional sliding rail
and CMA.
The sliding rail system for the T640 provides tool-less support for racks with square or unthreaded round mounting holes including all
generations of Dell racks. The sliding rails for the T640
offers
native support for threaded hole racks via the ReadyRails II mounting
interface. The rails ship in the tool-less mounting
configuration
but can be converted to the tooled
configuration
very quickly and
easily.
The optional cable management arm (CMA) can be mounted on either the left or right side of the rails without the use of tools for
fast and easy deployment.
Cable arm management (CMA)
The optional cable management arm (CMA) for the T640 organizes and secures the cords and cables exiting the back of the server
and unfolds to allow the server to extend out of the rack without having to detach the cables. Some key features of the T640 CMA
include:
•
Large U-shaped baskets to support dense cable loads.
Both the CMA and the tray mount without the use of tools via simple and intuitive snap-in designs.
•
Open vent pattern for optimal
airflow.
•
Can be mounted on either side by simply swinging the attachment housings from one side to the other.
•
Utilizes hook-and-loop straps rather than plastic tie wraps to eliminate the risk of cable damage during cycling.
•
Includes a low
profile fixed
tray to both support and retain the CMA in its fully closed position.
Rails
The ReadyRails II sliding rails for the T640 support tool-less mounting in 19 inch-wide, EIA-310-E compliant square hole and
unthreaded round hole 4-post racks. They also support tooled mounting in threaded hole 4-post racks and are available with or
without the optional cable management arm (CMA).
