NOTE
Radio transmit power is not used as one of the factors to determine the available power budget. If
an external power supply is used, it is assumed it will provide full power. When operating using full
power, each radio has 3x3 antenna mode support and its intended transmit power budget.
Radios at Full Power
The table below describes the maximum transmit power available to each radio (at varying data
rates) when the access point is receiving full DC power and is not compromised in its power budget.
These values should be viewed as the safe limit for the access point’s radio at full power and
should not be exceeded.
Radios at Low Power
The table below describes the maximum transmit power available to each radio (at varying data
rates) when the access point is receiving low DC power in either af or at mode.
CAUTION
Exceeding the limits listed below can cause damage to the access point or cause the radio to
operate unpredictably. Thus, these values should be viewed as the safe limit for the access
point’s radio and should not be exceeded in either af or at mode.
