ii NetworkAIR RM Air Distribution Unit
General Information
Introduction The NetworkAIR RM Air Distribution Unit works with an
existing precision A/C system to deliver cool air to the
equipment contained in a NetShelter enclosure or other 19"
EIA-310-D enclosure with an open or removable floor. The Air
Distribution Unit, installed at the bottom of the enclosure, pulls
supply air directly into the enclosure, thereby preventing the
conditioned air from mixing with warm ambient air before it
reaches the equipment. The dual fans provide the increased air
flow needed to cool densely-packed equipment and improves
air delivery in poor static pressure areas, solving many of the
heat issues facing today’s data centers.
Features Features of the RM Air Distribution Unit include:
• Compact size (2 U)
• Dual input connectors for redundant power
• Two fans with independent switches
• Replaceable air filter—initial efficiency G4 per EN
1822.

Safety Information
W
Disconnect power to the enclosure before installing the
Air Distribution Unit. Failure to do so may result in
arning
personal injury or damage to equipment.
Check to see that a fan guard is securely in place over
each of the air inlet openings.
Do not apply power to the unit until the installation is
complete. The Air Distribution Unit contains moving
parts, which are potentially hazardous when operated
outside of the enclosure.
Keep fingers and clothing away from the fans. When
powered on, they have moving parts which can cause
personal injury.
Do not attempt to move a heavily loaded enclosure by
yourself. Doing so introduces risk of injury due to muscle
strain or the tipping of the enclosure. Fully loaded
enclosures require at least two persons to move safely.
Keep the included alcohol swab away from sparks or
open flames.
Check that the power cord plugs and sockets are in good
condition before installation.
Connect the Air Distribution Unit to an IEC C-13 outlet.
The outlet must be connected to appropriate branch
circuit/mains protection (fuse or circuit breaker).
Connection to any other type of outlet may result in a
shock hazard.
This equipment contains potentially hazardous voltages.
Do not attempt to disassemble the unit.
Always install and operate the Air Distribution Unit as
shown in this manual.

Overview
Tools required You will need the following to install the Air Distribution Unit:
• Pencil
• Saw or other tool for cutting a hole in the raised floor
tile(s) (raised floor application only)
• Caged nut tool (provided)
• 7-mm spanner or nut driver
• Phillips screwdriver
Overview of the installation procedure
Equipment placement
The Air Distribution Unit can be installed in both raised-floor
and non–raised-floor applications. The unit is installed in the
bottom 2U of the NetShelter enclosure or other 19" EIA 310-D
enclosure with an open or removable floor. The raised floor
application will require an opening in the raised floor, directly
under the enclosure. With the enclosure in place, install several
parts of the Air Distribution Unit so that you can mark the
location and size for this opening. Then move the enclosure
and remove the floor tile(s) to cut the opening. After
reinstalling the tiles and the enclosure, complete the
installation. See the following paragraphs in this section for the
installation procedure.
To avoid interference with air flow, use the uppermost part of
the enclosure for any equipment that extends forward over the
air outlet of the Air Distribution Unit.
