Data Sheet

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.
