About this task
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)
The 802.11ax AP3xx, AP4xx, and AP5xx 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
AP:
AP310i/e power mode
To operate in the normal mode AP310 has
to be powered from:
- GE1 POE connected to AT
switch, or
- External power supply
source
To operate in the
low power mode AP310
has to be powered from:
- GE1 POE connected to
AF switch port and external power supply not connected.
Note
Low power mode
limitations are as follows:
- For AP310i: USB
port is turned OFF and Radio 2 (5 GHz) is limited to 2x2 with
max power of 20dBm.
- For AP310e: USB
port is turned OFF and Radio 2 (5 GHz) is limited to 2x2 with
max power of 18dBm.
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
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/e and
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
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).
