Fans
Five hot-swappable fans are mounted in a fan gantry that is located in the chassis between the hard
drive bay and the processors. Each fan has a blind mate 2x2 connector that plugs directly into the
planar. There is an additional fan integrated in each power supply to cool the power supply subsystem
and also provide additional cooling for the whole system. Single processor configurations will have four
fans populated.
The Embedded Server Management logic in the system monitors the speed of the fans. A fan failure
or over-temperature in the system results in a notification by iDRAC6. All system fans are pulse-width
modulated fans. Redundant cooling is supported with one fan failing at a time.

installation components are as follows: Sliding rack mount with latest generation Cable Management
Arm (CMA). When the system is installed in a rack, please observe the following guideline:
When the system is installed in a rack, only Dell-approved CMAs should be installed behind

the rack.
• Include the new simple and intuitive ReadyRail™ tool-less rack interface for square-hole and
round-hole racks.
• Provide significantly improved compatibility with non-Dell racks.
• Static rails for the R610 & R710 fit in all types of four-post and two-post racks available in the
industry including four-post threaded hole racks.
CMAs
• Provide much larger vent pattern for improved airflow through the CMA.
• Include a common support tray for eliminating CMA sag.
• Replaced tie wraps with hook and loop straps to eliminate risk of cable damage during cycling.
• Maintain key feature of being fully reversible with no conversion required.
