Table 3 Site requirements
Requirement DS60 Expansion Shelf
Vertical space in standard 19", 4-post rack 5U including a 1U Cable Managements Tray.
Do not use a two-post rack. See the slide rail
and installation documentation in the
packaging for installing in a rack.
Air conditioning Air conditioning that can cope with the
maximum BTU/hr thermal rating.
Temperature controls Adequate temperature control with a gradient
(change) not to exceed 30° C in an hour.
Front bezel clearance 1.56 inches (4.0 cm) of unobstructed
clearance.
Back panel clearance 5 inches (12.7 cm) of unobstructed clearance.
Airflow In a closed or multi-unit rack, ensure that the
unit has adequate airflow. If the equipment is
mounted in an enclosed (as opposed to a
four-post open rack), the front and rear doors
should have 65% minimum open area for
airflow. Whether in an open or enclosed rack,
use filler panels to prevent hot air re-
circulation. The rack design and installation
should take into consideration the maximum
ambient operating temperature of the
equipment, which is 35° C.
Power/grounding The Power distribution within the rack should
provide a safe electrical earth connection.
Voltage should be 200-240 VAC; 50 or 60 Hz.
Plug four power cords - two from each power
supply into separate branch circuit supplies
for redundancy—one set of cords from one
power supply goes to one branch and the
second set of cords from the other power
supply goes to a different branch. Each
receptacle must be capable of safely
supplying 0.94 amps from each power socket
or 1.87 amps from each socket in case of a
redundant circuit.
