In a normal rack mount configuration the PathBuilder S700 shelf is 22.75" x 19" x
11.81" including cables. If the PathBuilder S700 is mounted in an enclosure, plan
on enough clearance at the front and back for cable and wiring service loops.
CAUTION: The PathBuilder S700 chassis includes a fan tray, and a minimum gap
of one RU (rack unit) is required between the chassis and any convection cooled
equipment.
CAUTION: Many of the integrated circuits on the modules are sensitive to static
electricity. Do not handle the plug-in modules without wearing a properly
grounded, antistatic, wrist strap. When removing the modules from the shelf,
place them printed-circuit side down on a nonconducting, static-free, flat surface.
