predrilled for 18" (457.2mm) chassis slides (see Table 1-2).
(c) For applications which require less depth protrusion of the rack adapter within the rack, the
rack adapters provide two “set-back” positions for use with optional notched mounting ears
(see Tables 1-1 and 1-2); see Figure 2-4 for set-back dimensions.
For all installations provide adequate clearance around air inlet and exhaust locations and
ensure that the temperature immediately surrounding the unit, and especially near the air inlets,
does not exceed the maximum specified ambient temperature for the operating conditions of the
installed power supplies.
