This maintains a lower center of gravity and reduces thepossibility of the rack tipping.2 Anti-tipping feet, if available with the rack, should always be extended.3 The heaviest instrument of chassis should always be mounted at the bottomof the rack.4 For maximum cooling and optimum rack thermal efficiency, place theinstrument or chassis with the greatest power consumption towards the top ofthe rack. This promotes efficient cooling since heat rises when placed nearerto the top of the rack, high power instruments will not unnecessarily heatother instruments. However, in doing this, do not violate the guideline thatthe heaviest instruments should be placed at the bottom of the rack.5 If instruments or modules in the chassis are consuming maximum power, 1Uof rack space is required for ventilation below the M9018A chassis.1 kit Rack Flange and Handles Kitincludes quantity 8, Rack Flange Screws,M4x10 Flat HeadM9018-000201 kit Support Rails M9018-000018 Channel Nuts (4 for support rail-to-rack, 4 forrack flanges)0590-08044 Support Rail-to-Rack Screws - 10-32 x 0.5 2680-02784 Dress Screws for Rack Flanges E9900-06001
