• Before installing a Model 106 enclosure into the rack, see the CAUTION on page 10 and the WARNING
on page 34.
• The rack construction must be capable of supporting the total weight of the installed enclosures. The
design should incorporate stabilizing features suitable to prevent the rack from tipping or being pushed
over during installation or in normal use.
• When loading a rack with enclosures, fill the rack from the bottom up; and empty the rack from the top
down. Heavier enclosures should be located beneath lighter enclosures for optimal stability.
• Do not try to lift the enclosure by yourself.
CAUTION: To avoid danger of the rack falling over, under no circumstances should more than
one enclosure be moved out of the cabinet at any one time.
– The system must be operated with low pressure rear exhaust installation. The back pressure
created by rack doors and obstacles is not to exceed 5 pascals (0.5 mm water gauge).
– The rack design should take into consideration the maximum operating ambient temperature
for the enclosure, which is 35ºC (95ºF) for JBODS/EBODs. Above an altitude of 900 meters,
derating applies as per ASHRAE Class A2.
– The rack should have a safe electrical distribution system. It must provide over-current
protection for the enclosure and must not be overloaded by the total number of enclosures
installed in the rack. When addressing these concerns, consideration should be given to the
electrical power consumption rating shown on the nameplate.
– The electrical distribution system must provide a reliable earth connection for each enclosure
in the rack.
– Each power supply line cord will have an earth leakage current of 1mA. The design of the
electrical distribution system must take into consideration the total earth leakage current
from all the PSUs in all the enclosures. The rack will require labeling with “High Leakage
Current. Earth connection essential before connecting supply.”
– The rack—when configured with the enclosures—must meet the safety requirements of all
applicable safety standards.
