100 Percent Throughput Switch Power Consumption (with maximum PoE loads)
The numbers indicate the power consumed by a typical system (the switch and the corresponding
PoE loads) under normal conditions. Normal conditions signify a temperature of 25 degrees
Celsius, atmospheric pressure in the range of 860 to 1060 mbar and relative humidity from 30 to
75 percent. Typically this power draw is realized when a switch is running 100 percent traffic load
of 64 byte sized packets on all its ports and uplinks and also drawing 100 percent PoE load .
5 Percent Throughput Switch Power Consumption (with 50 percent PoE loads).
The numbers indicate the power consumed by a typical system (the switch and the corresponding
PoE loads) under normal conditions. Normal conditions signify a temperature of 25 degrees
Celsius, atmospheric pressure in the range of 860 to 1060 mbar and relative humidity from 30 to
75 percent. The numbers below indicate a 5 percent traffic load and 50 percent PoE load on the
switch and its uplinks.
Table 6 lists the specifications of all the power supplies supported in Cisco Catalyst 3750-E Series
Switches.
