Rack Enclosure Requirements
The server is designed so that you can install it into a 72-inch (184-cm) tall Sun
expansion cabinet or other EIA-compliant industry-standard rack enclosure that
meets the requirements listed in the table below. You need a Sun rackmounting kit
for each server that you will rackmount.
Rack Enclosure Feature
Requirement
Load Bearing Capacity
The rack must firmly support the weight of as many Sun
Fire 280R servers as you are installing into the rack (each
weighs up to 75 lb, 34 kg), plus the weight of the
rackmounting hardware, and the weight of any other
installed devices.
Vertical Space Requirements
Each server requires four rack units (7 inches, 17.78 cm)
of vertical space for rack installation. A 72-inch (184-cm)
cabinet can hold up to nine servers.
Airflow
The system requires 113 cfm at 40
o
C and 10,000
feet. This airflow rate corresponds to 328 lb/hr at
any altitude and to 78 cfm at 40
o
C and sea level.
For proper ventilation, each system in the rack enclosure
requires 28 square inches (181 square cm) of unrestricted
airflow into the front of the system, and 23 square inches
(148 square cm) of unrestricted exhaust port at the back of
the system. Maintain a minimum 1.5 inches (3.8 cm)
clearance between the system and any front or back doors.
