Rack Installation - Dell PowerEdge R940 Technical Manual

detach the cables. The SRB is a bar that supports large cable loads and also allows the server to extend out of the rack without having to
detach the cables if cable service loops are created.
Some key features of the CMA include:
• Large U-shaped baskets to support dense cable loads
• Open vent pattern for optimal airflow
• Ability to be mounted on either side by simply swinging the spring-loaded brackets 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
• Both the CMA and the tray mount without the use of tools via simple and intuitive snap-in designs
Some key features of the SRB include:
• Sturdy bar that supports large cable loads.
• Controls stresses on connectors.
• Utilizes hook-and-loop straps rather than plastic tie wraps to make securing cables quick and eliminates the risk of cable damage.
• Cables can be segregated into discrete, purpose specific bundles.
• Attaches to the rails without the use of tools via simple and intuitive latching design.
The CMA can be mounted to either side of the sliding rails without the use of tools or the need for conversion. However, it is recommended
that it be mounted on the side opposite to the power supplies to allow easier access to the power supplies and rear hard drives (if
applicable) for service or replacement.

Rack Installation

The sliding rails are a "drop-in" design. This means that the system is installed vertically into the rails by inserting the standoffs on the sides
of the system into the "J-slots" in the inner rail members with the rails in the fully extended position. As with all 2U systems, a minimum of
two people are required in order to properly install the system in the rails.
