b Secure the cover with the eight assembly screws you removed in step 1a.
In a normal rack mount configuration the PathBuilder S330/S310 switch is 3.5" x
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 19 for details. If the PathBuilder S330/S310
switch is mounted in an enclosure, plan on enough clearance at the front for cable
and wiring service loops.
To mount the shelf:
1 Attach 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.
2 Adjust the rack-mount ears if necessary for 19" installation. See Figure 19.
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.
