To configure a static IP address:
(Instant AP)# ip-address <IP-address> <subnet-mask> <NextHop-IP> <DNS-IP-address> <domain-
name>
Configuring External Antenna
If your IAP has external antenna connectors, you need to configure the transmit power of the system. The
configuration must ensure that the system’s Equivalent Isotropically Radiated Power (EIRP) is in compliance with
the limit specified by the regulatory authority of the country in which the IAP is deployed. You can also measure or
calculate additional attenuation between the device and antenna before configuring the antenna gain. To know if your
AP device supports external antenna connectors, see the Install Guide that is shipped along with the AP device.
EIRP and Antenna Gain
The following formula can be used to calculate the EIRP limit related RF power based on selected antennas
(antenna gain) and feeder (Coaxial Cable loss):
EIRP = Tx RF Power (dBm)+GA (dB) - FL (dB)
The following table describes this formula:
Formula Element Description
EIRP Limit specific for each country of deployment
Tx RF Power RF power measured at RF connector of the unit
GA Antenna gain
FL Feeder loss
Table 16: Formula Variable Definitions
Example
For example, the maximum gain that can be configured on an IAP-134 with AP-ANT-1F dual-band and omni-
directional antenna is as follows:
Frequency Band Gain (dBi)
2.4-2.5 GHz 2.0dBi
4.9–5.875GHz 5.0dBi
Table 17: Maximum Antenna Gains
For information on antenna gain recommended by the manufacturer, see www.arubanetworks.com.
Configuring Antenna Gain
You can configure antenna gain for APs with external connectors using Instant UI or CLI.
In the Instant UI
1. Navigate to the Access Point tab, select the access point to configure and then click edit.
