Rack-mount Requirements 
CAUTION 
For rack-mounted installations, the following criteria must be observed (in 
addition to the Environmental Requirements listed on page 17). 
Mounting & Support 
ALWAYS use additional support at the sides or rear of the VN-QUANTUM card frame. For example, 
by installing a suitable rack-mountable shelf beneath the unit, fixed to both the front and rear rack 
posts. Ensure that the shelf (or other mounting accessories) can support the full weight of the unit: 
  The ES3301-2 weighs up to 27.5kg / 61 lbs (when fully populated) 
  The ES3302 & ES3304  weighs up to 17.5kg / 38.6 lbs (when fully populated) 
NEVER rely on the integral rack-mount brackets to support the full weight of the unit. These must only 
be used to secure the unit within the rack. 
DO NOT stand other units directly on top of the VN-QUANTUM Processor when it is rack-mounted as 
this may overload the mountings. 
Ventilation 
ALWAYS ensure that the rack enclosure is adequately ventilated. Sufficient airflow must be achieved 
(by convection or forced-air cooling) to satisfy the ventilation requirements of all items of equipment 
installed within the rack. 
A ventilation gap of at least 100mm must be left between the front and rear panels of the VN-
QUANTUM Processor and adjacent surfaces or equipment. 
No ventilation space is necessary above or below the VN-QUANTUM Processor. 
Mains Supply 
ALWAYS ensure that the mains power supply is of the correct voltage and frequency for all 
equipment within the rack, and that it has a good ground/earth connection. 
Where a power strip (mains distribution batten) is used (of either a hard-wired or plug and socket 
type), always ensure that the current rating of both the power strip and the supply is sufficient for all 
equipment within the rack. Refer to the equipment rating plates or user documentation to establish 
power requirements.
