Technical Specifications

Rack Airflow

Requirements

Rack 10000 series cabinets

The increasing power of new high-performance processor technology requires increased cooling

efficiency for rack-mounted servers. The 10000 Series Racks provide enhanced airflow for maximum

cooling, allowing these racks to be fully loaded with servers using the latest processors.

CAUTION:

CAUTION: If a third-party rack is used, observe the following additional requirements to ensure

CAUTION:

adequate airflow and to prevent damage to the equipment:

Front and rear doors: If your 42U server rack includes closing front and rear doors, you must

allow 830 square inches (5,350 sq cm) of hole evenly distributed from top to bottom to permit

adequate airflow (equivalent to the required 64 percent open area for ventilation).

The clearance from face of rack to inside of the front door needs to be 1.75" minimum.

Side: The clearance between the installed rack component and the side panels of the rack must be

a minimum of 2.75 inches (7 cm).

Depth: Minimum 39.4 inches (1000mm)

Adjustable rack rails are shipped with each enclosure:

Minimum rail length: 25 inches (635mm)

Maximum rail length: 34 inches (864mm)

CAUTION:

CAUTION: Always use blanking panels to fill all remaining empty front panel U-spaces in the rack. This

arrangement ensures proper airflow. Using a rack without blanking panels results in improper cooling

that can lead to thermal damage.
