Note: Disclaimer: All power consumption numbers were measured under controlled laboratory conditions and are
provided as an estimate.
The wattage rating on the power supply does not represent actual power draw. It indicates the maximum power draw
possible by the power supply. This rating can be used for facility capacity planning. For PoE switches, cooling
requirements are smaller than the actual power consumption as a significant portion of PoE loads are dissipated in
the endpoints.
Non-PoE Power Consumption
100 Percent Throughput Switch Power Consumption
The numbers indicate the power consumed by a typical switch 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 such power draws are only seen when encountering a 100 percent traffic load made
up entirely of 64-byte packets on the switch and the uplinks.
5 Percent Throughput Switch Power Consumption
The numbers indicate the power consumed by a typical switch 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 on the switch and its uplinks.
PoE Power Consumption
100 Percent Throughput Switch Power Consumption (No PoE Loads)
The numbers indicate the power consumed by a typical switch 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 such power draws are only seen when encountering a 100 percent traffic load made
up entirely of 64-byte packets with no PoE loads on the switch and uplinks.
Measured 5 Percent Throughput Switch Power Consumption (No PoE Loads)
The numbers indicate the power consumed by a typical switch 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 on the switch and its uplinks
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.
