MSM7xx Controllers Configuration Guide v6.4.0

When using antennas not originally supplied with the AP, it is your responsibility
to ensure that the Transmit power control settings are configured so that the radio
will not exceed permissible power levels for the regulatory domain in which the AP
is operating. Depending on the regulatory domain, the specific antenna chosen,
the wireless mode, channel width, band or channel selected, you may need to
configure the radio with a reduced transmit power setting. When using Automatic
channel selection with an external antenna in the 2.4 GHz band, all channels must
be set to the lowest acceptable value for your regulatory domain.
CAUTION: For specific power limits according to your regulatory domain, consult
the Antenna Power-Level Settings Guide available at www.hp.com/support/manuals.
Search for the part number of your antenna.
For example, if you install an external 8 dBi directional antenna, and the maximum
allowed power level for your country is 15 dBm, you may have to reduce the transmit
power level to be in compliance.
If you change the antenna at a later time, you must get the latest version of the
Antenna Power-Level Settings Guide, and again reassess and possibly adjust radio
power settings according to the antenna used.
When setting Transmit power control to comply with information in the Antenna
Power-Level Settings Guide, always set radio power in dBm, and not as a
percentage.
Maximum output power
Shows the maximum output power that can be supported by the radio based on the regulatory
domain.
• On the MSM410, MSM430, and MSM460MSM317: Shows the maximum EIRP
(Effective/Equivalent Isotropic Radiated Power) that can be delivered by the AP based on
the regulatory domain. The displayed EIRP power is equivalent to the Conducted RF transmit
power of the radio (dBm) plus the array gain of the antenna (dBi). EIRP is only displayed
on the HP 425 when using internal antennas.
• On the MSM466 and MSM466-R: Shows the maximum conducted RF power (dBm) that
can be delivered to the external antenna. The EIRP can be calculated by adding the antenna
array gain (dBi).
Use maximum power
Select this checkbox to use the maximum available output power.
Set power to
Specify the transmission power in dBm or as a percentage of the maximum output power.
When you click Save, percentage values are rounded up or down so that the dBm value is
always a whole number.
Note that the actual transmit power used by the radio may be less than the specified value.
The AP determines the maximum power to be used based on the regulatory domain.
Supported power levels are as follows:
• 0 - 20 dBm: MSM310, MSM317, MSM320, MSM335, MSM410, MSM422, MSM466,
MSM466-R
• 5 - 25 dBm: MSM430, MSM460 operating at 2.4 GHz.
• 7 - 20 dBm: MSM430, MSM460 operating at 5 GHz.
• 4 - 27 dBm: HP 425 operating at 2.4 GHz.
• 5 - 28 dBm: HP 425 operating at 5 GHz.
