Series K FortiAPs can be energized through the PoE and DC adapters.
When connected through a DC adapter or PoE 802.3bt (60W to 90W), the FortiAPs K series will work on its 'Full mode':
802.3bt / DC : Full – Tx Power Full ; Chain 4x4; USB Enabled
Whereas while connected through PoE 802.3at, the FortiAPs K series will work with Radio 1 (2.4Ghz) and Radio 2 (5GHz) at 17dBm maximum and USB will be disabled. Essentially, they will be working on 'Low mode':
802.3at : R1(2.4Ghz) and R2(5 GHz) operation in Low Tx Power 17dBm ; Chain 4x4; USB – Disabled
This information can be confirmed in the FortiAP datasheet.
It is possible to verify which mode a FortiAP is working in by executing the command below on the FortiAP CLI:
cw_diag power
For example:
================================================================================
OUTPUT of command cw_diag power:
================================================================================
Power Detection Data: dc=0 ps1=1 af1=0 at1=1 psv1=0 bt1=0 ps2=0 af2=0 at2=0 psv2=0 bt2=0
Budget lldp 22,0 poe 25,0 (dc=99 af=13 at=25 psv=60 bt=50 full=43.0 low=24.9)

Radio 1: MaxTxpower 37 TxChainMask 0x01 RxChainMask 0x01
Radio 2: MaxTxpower 37 TxChainMask 0x01 RxChainMask 0x01
Radio 3: MaxTxpower 17 TxChainMask 0x01 RxChainMask 0x01
Radio 4: MaxTxpower 17 TxChainMask 0x05 RxChainMask 0x05
USB: disabled
full:usb,all radios,txpower full,chain 4; high:2G/5G radio,txpower 17dBm,chain 2; low:disable all radios
In this example, it can be observed that the FortiAP is working with a PoE 802.3at, which means that the FortiAP will work with Radio 1 (2.4Ghz) and Radio 2 (5GHz) at 17dBm maximum, Radio 3 (6GHz) will be disabled and USB will be disabled.
