APPENDIX D
Safety Agency Recognition
Plenum Installation
Compliance with NRTL/UL 1950/EN60950
Safety agency regulations require the use of an approved plenum
(Patton part number (05R16PL) with each 1001R rack installation.
A rack chassis fitted with the plenum constitutes an agency recog-
nized fire enclosure. All 1001R rack installations require at least
one plenum to be fitted underneath the bottom-most chassis in the
system for continued compliance with agency regulations.
Thermal Management
Due to the small size and high performance of the 1001R rack
system, a fully-loaded rack chassis may generate a considerable
amount of heat. To ensure long equipment life, it is important the
thermal management guidelines are adhered to in all 1001R
installations. In high density, stacked configurations, additional
plenums may be required between each chassis to improve sys-
tem thermal performance. Ambient air temperature, total rack
power dissipation and the number of stacked units must all be
considered when determining cooling requirements. For further
information, see the application note “Thermal Management
Guidelines for the 1001R Rack System”, available on Patton’s
website at www.patton.com.
