power-config

Profile Config Commands

Configures the power option mode. Use this command in the profile configuration mode to configure the transmit output power of access point radios. This command is also available in the device-config mode.

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 802.11ax AP5XX and AP4XX model access points can be powered up with POE or through an external power source. These APs support both IEEE 802.3af and 802.3at standards. If connected to a POE AT power source (25W) or external power source, the APs operate in normal mode with full performance. If connected to a POE AF power source (14.5W), the APs operate in low power mode with limited performance.

Consider the following information before configuring the power mode of the AP4XX and AP5XX model access points:

AP4XX (AP410i/e and AP460i/e) power mode

To operate in the normal mode AP410 and AP460 have to be powered from:

  • GE1 POE connected to AT switch, or
  • External power supply source
To operate in the low power mode AP410 and AP460 have to be powered from:
  • GE1 POE connected to AF switch port and external power supply not connected.
Note

Note

Low power mode limitations are as follows:
  • For AP410i: USB port is turned OFF and Radio 2 (5 GHz) is limited to 2x2 with max power of 20dBm.
  • For AP410e: USB port is turned OFF and Radio 2 (5 GHz) is limited to 2x2 with max power of 18dBm.
  • For AP460i: Radio 2 (5 GHz) is limited to 2x2 with max power of 22dBm.
  • For AP460e: Radio 2 (5 GHz) is limited to 2x2 with max power of 20dBm.

AP5XX (AP510i/eand AP560i/h) power mode

To operate in the normal mode AP510 and AP560 have to be powered from:
  • GE1 POE connected to AT switch port and GE2 is not connected, or
  • GE2 POE connected to AT switch port and GE1 is not connected, or
  • Both GE1 and GE2 POE connected to AT switch port, or
  • External power supply source
To operate in the low power mode AP510 and AP560 have to be powered from:
  • GE1 POE connected to AF switch port and external power source not connected, or
  • GE2 POE connected to AF switch port and external power source not connected
Note

Note

Low power mode limitations are as follows:
  • For AP510:
    • Mode 1: Radio 1 (2.4 GHz) and Radio 2 (5 GHz) is limited to 2x2 with max power of 20dBm.
    • Mode 2: Radio 1 (sensor) and Radio 2 (5 GHz) is limited to 2x2 with max power of 20dBm.
    • Mode 3: Radio 1 (5 GHz) is limited to 2x2 with max power of 18dBm and Radio 2 (5 GHz) is limited to 2x2 with max power of 0dBm (providing no service).
  • For AP560:
    • Mode 1: Radio 1 (2.4 GHz) and Radio 2 (5 GHz) is limited to 2x2 with max power of 16dBm.
    • Mode 2: Radio 1 (sensor) and Radio 2 (5 GHz) is limited to 2x2 with max power of 16dBm.
    • Mode 3: Radio 1 (5 GHz) is limited to 2x2 with max power of 18dBm and Radio 2 (5 GHz) is limited to 2x2 with max power of 0dBm (providing no service).

AP505 mode of functioning (normal/low power):

To operate in the normal mode AP505 has to be powered from:
  • GE1 POE connected to AT switch port, or
  • External power supply source
To operate in the low power mode AP505 has to be powered from:
  • GE1 POE connected to AF switch port and external power source not connected

Syntax

power-config [af-option|at-option|mode|usb-enable]
power-config [af-option|at-option] [range|throughput]
power-config mode [auto|3af]
power-config usb-enable

Parameters

power-config [af-option|at-option] [range|throughput]
power-config Configures the power option mode
af-option [range|throughput] Configures the 802.3.af power mode option. The options are:
  • range – Configures the AF power range mode. This mode provides higher power but fewer transmission (tx) chains.

Select range when range is preferred over performance for broadcast/multicast (group) traffic. The data rates used for range are the lowest defined basic rates.

  • throughput – Configures the af power throughput mode. This mode provides lower power but has more tx chains. This is the default setting.

Select throughput to transmit packets at the radio‘s highest defined basic rate (based on the radio‘s current basic rate settings). This option is optimal in environments where transmission range is secondary to broadcast/multicast transmission performance.
at-option [range|throughput] Configures the 802.3 at power mode option. The options are:
  • range – Configures the AT power range mode. This mode provides higher power but fewer tx chains.

Select range when range is preferred over performance for broadcast/multicast (group) traffic. The data rates used for range are the lowest defined basic rates.

  • throughput – Configures the at power throughput mode. This mode provides lower power but has more tx chains. This is the default setting.

Select throughput to transmit packets at the radio‘s highest defined basic rate (based on the radio‘s current basic rate settings). This option is optimal in environments where transmission range is secondary to broadcast/multicast transmission performance.
