Requirement DD120 DD5xx, DD5xxg, DD4xx, DD4xxg
Vertical space in
standard 19”, four
post rack
U = 1.75" 1U 3U
Do not use a two-post rack. See the slide rail and installation documentation in the
packaging for installing in a rack.
If a Data Domain system is installed in a rack with limited space above the Data
Domain system, use cables that are long enough to allow sliding the Data Domain
system out on the slide rails for servicing.

Ventilation & Airflow In a closed or multi-unit rack, ensure that the unit has adequate airflow through
front bezel and back panel and that the ambient air temperature requirements are
met. Ensure that the front bezel and back panel clearances are met. Back pressure
by rack doors and obstacles not to exceed 5 pascals (0.5 mm. water gauge
pressure or 0.9997 psi).
Front Bezel Clearance 1.54 inches (4 cm) of unobstructed clearance (Bezel on)
Back Panel Clearance Five inches (12.7 cm) of unobstructed clearance
