(48.3 cm) rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Industry Association (http://www.eia.org). Rack Requirements • The outer edges of the mounting brackets extend the width of either chassis to 19 in. (48.3 cm). • The front of the chassis extends approximately 0.5 in. (1.27 cm) beyond the mounting ears. • Maximum permissible ambient temperature when two devices are placed side by side in a 19 in. rack is 40ο C. • In a rack, two devices should be placed in alternate slots and not adjacent. NOTE: If you use a front-mount rack, we recommend you support the back of the device with a shelf or other structure. Spacing of Mounting Bracket and Flange Holes • The holes within each rack set are spaced at 1 U [1.75 in. (4.5 cm)]. The device can be mounted in any rack that provides holes or hole patterns spaced at 1-U [1.75 in. (4.5 cm)] increments. • The mounting brackets and front-mount flanges used to attach the chassis to a rack are designed to fasten to holes spaced at rack distances of 1 U (1.75 in.). • The mounting holes in the mounting brackets provided with the device are spaced 1.25 in. (3.2 cm) apart (top and bottom mounting hole). Connecting to the Building Structure Always secure the rack in which you are installing the services gateway to the structure of the building. If your geographical area is subject to earthquakes, bolt the rack to the floor. For maximum stability, also secure the rack to ceiling brackets.
