Installing AirSpeed Multi Stream in a Rack
The AirSpeed Multi Stream is designed for 19-inch (483-mm) rack enclosures and requires
one and a half EIA rack units (1.5RU), or 2.6 inches (66.7-mm) of rack space. AirSpeed
Multi Stream provides rack nuts for those rack enclosures that do not have threaded holes.
Rack-nut clips position the rack nuts at the holes of the rack and are used to secure the rack
components in place.
The AirSpeed Multi Stream ships with brackets, and rack-mount screws. If your rack has
threaded holes, you might have to supply your own rack fasteners. If your rack does not have
threaded holes, install the rack nuts included with the AirSpeed Multi Stream.
c
The AirSpeed Multi Stream is designed to be installed horizontally in a rack. Installing
the AirSpeed Multi Stream on an angle or in a sloped console causes the internal drives
to wear faster than the intended life of the drive.

To ensure the stability of the rack enclosure, start from the bottom when you install the
rack components in the rack enclosure.
Rack-mount Requirements
The following rack-mount requirements are listed below:
• Elevated Operating Ambient — If installed in a closed or multi-unit rack assembly, the
operating ambient temperature of the rack environment might be greater than room
ambient. Therefore, consider installing the equipment in an environment compatible
with the maximum ambient temperature (Tma) specified by the manufacturer.
• Reduced Air Flow — Installation of the equipment in a rack should be such that the
amount of air flow required for safe operation of the equipment is not compromised.
AirSpeed Multi Stream airflow is from the front of the chassis enclosure to the rear.
Make allowances for cooling air to be available to the front panel surface and no
restrictions at the rear.
• Mechanical Loading — Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
• Circuit Overloading — Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits might have
on overcurrent protection and supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this concern.
• Reliable Earthing — Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections other than direct
connections to the branch circuit (for example, use of power strips).
