Site-Planning Checklist

1 - IEEE class 3 device	17.3	W
total output power	284	W

Total heat dissipated by system = (284/.75) * 3.415 = 1293 BTUs/hr

Note Although a class 3 device needs 15.4 W to power up, 17.3 W need to be generated from the backplane in order to have 15.4 W at the switch port. 17.3 W comes from the WS-X4248-RJ45V DC-DC converter’s efficiency (89%).
