Catalyst 4500 Series Switches Installation Guide
78-14409-08
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%).
Site-Planning Checklist
Table 2-2 lists the site-planning activities that you should complete before you
install a Catalyst 4500 series switch. Completing each activity helps to ensure a
successful switch installation.
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
