bSecure the cover with the eight assembly screws you removed in step 1a.

Step 2: Install the Unit in In a normal rack mount configuration the PathBuilder S330/S310 shelf is 3.5" x the Rack 17" x 15.5" including cables. Since the equipment is cooled with two internal

fans, clearance at the top is not needed; however, convection cooled equipment must not be mounted directly under the shelf.Allow at least one rack unit clearance below the unit. See Figure 14 for details. If the PathBuilder S330/S310 is mounted in an enclosure, plan on enough clearance at the front for cable and wiring service loops.

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.

To mount the shelf, follow these steps:

1Attach the rack-mount ears to the unit, following the instructions supplied with the ears.

CAUTION: When attaching the rack-mount ears, you must use the factory-supplied screws. Using screws other than those supplied with the rack-mount ears voids your warranty and could damage the PCB.

2Adjust the rack-mount ears if necessary for 19" installation. See Figure 14.

CAUTION: Do not block the ventilation openings on the top and bottom of the unit during installation. A minimum of 1 rack unit (1.75”) space is required.
