Overview / DescriptionRack installation components such as rails are provided with the PowerEdge R710 Rack Kit. The rackinstallation components are as follows: Sliding Rack mount with latest generation Cable ManagementArm (CMA). When the system is installed in a rack, please observe the following guidelines:Nothing should be located within 12" of the front of the unit that would restrict the airflow into the system.Nothing should be mounted or placed behind the chassis that would restrict airflow from exiting thesystem. Only Dell approved CMAs can be placed behind the chassis. All other objects should be locatedat least 24" away from the rear of the chassis.When two systems are placed back to back, the separation between the units should be at least 24" ifthe exit airflow is equivalent for the two chassis. This allows the exit air to escape without creating anextreme back pressure at the rear of one of the chassis.b. cable management arm (cma)Notes: • CMA supports for the maximum number of cables supported by system• The numbers in this matrix represent the number and types of external cables required to besupported by the CMA solution.• This matrix is built on the practical worst case configuration in each platform based on priorand projected take rates. Note that other combinations of adapters and associated cables exist,but are assumed to fall within these guidelines from the standpoint of bend radius andflexibility, cable bundling, cable volume, etc.• PCI NIC cables are assumed to be Ethernet.• KVM cable dongle may be used for mouse/keyboard/video.cable tyPe numbeR Of cablesMouse – USB 1Keyboard – USB 1Video – VGA 1Power Cords 2LOMs – Ethernet 1PCI NICs 1Total 8
