Description |
This article describes an issue that occurs where the operating channel shows as '0' on both Radio0(2.4GHz) and Radio1(5GHz) in 431G/433G access points. The issue is mainly seen in new deployments. |
Scope | FortiAP 431G/433G. |
Solution | In a scenario where the operating channel shows as '0' in 431/433G access point, the radio configuration on the AP is as follows:
# rcfg Radio 0: AP channel : num=0 oper_chan : 0 r_ac md_cap : 1, 6, 11, r_ac chan list : 1, 6, 11, chan list : 1, 6, 11,
Radio 1: AP channel : num=0 oper_chan : 0 chan list : 36, 40, 44, 48, 149, 153, 157, 161, 165, hw_chan list : 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 144, 149, 153, 157, 161, 165,
This issue is seen when only 802.3af power is provided to the AP. As a result, the poe status shows as low:
poe mode : low(auto) poe mode oper : low usb port : disabled
All radio interfaces must be disabled for 802.3af power. The access point needs to be provided with 802.3at or 802.3bt power to enable radio interfaces.
A relevant snippet from the datasheet for FortiAP 431G/433G:
PoE Mode 802.3af : Low – All Radios Disabled ;USB – Disabled 802.3at : High – Tx Power Full;Chain 2x2; USB – Disabled 802.3bt / DC : Full – Tx Power Full ; Chain 4x4;USB – Enabled
On a fully powered access point , poe mode shows as follows:
poe mode : high(auto) poe mode oper : high
