4. Select + Add Row below the Network Time Protocol (NTP) table to define the configurations of
NTP server resources used to obtain system time. Up to 3 NTP servers can be configured. Set
the following parameters to define the NTP configuration:
Use the RF Domain Manager field to configure how this access point behaves in standalone mode.
Set the following parameters:
5. Select OK to save the changes made to the general profile configuration. Select Reset to revert
to the last saved configuration.
Profile Radio Power
System Profile Configuration
Use the Power screen to set one of two power modes (3af or Auto) for the access point profile.
When Automatic is selected, the access point safely operates within available power. Once the
power configuration is determined, the access point configures its operating power characteristics
based on its model and power configuration.
An access point uses a complex programmable logic device (CPLD) to manage power. The CPLD
determines proper supply sequencing, the maximum power available and other status information.
One of the primary functions of the CPLD is to determine the maximum power budget. When an
access point is powered on (or performing a cold reset), the CPLD determines the maximum power
provided by the POE device and the budget available to the access point. The CPLD also
determines the access point hardware SKU (model) and the number of radios.
If the access point’s POE resource cannot provide sufficient power to run the access point (with all
intended interfaces enabled), some of the following interfaces could be disabled or modified:
• The access point’s transmit and receive algorithms could be negatively impacted
• The access point’s transmit power could be reduced due to insufficient power
• The access point’s WAN port configuration could be changed (either enabled or disabled)
To define an access point’s power configuration:
1. Select the Configuration tab from the Web UI.
2. Select Devices.
AutoKey Select this option to enable an autokey configuration for the NTP resource. The default setting is
disabled.
Key If an autokey is not being used, manually enter a 64 character maximum key the access point and
NTP resource share to securely interoperate.
Preferred Select this option designate this particular NTP resource as preferred. If designating multiple NTP
resources, preferred resources are given first opportunity to connect and provide NTP calibration.
Server IP Set the IP address of each server added as a potential NTP resource.
Version Use the spinner control to specify the version number used by this NTP server resource. The default
setting is 0.
Capable Select to enable this access point to act as a RF Domain Manager in a particular RF Domain.
Priority Select to prioritize this access point in becoming a RF Domain Manager in its; particular RF
Domain. The higher the value, the more likely the device becomes the RF Domain Manager for the
domain.
