PoE Requirements for Juniper Mist APs

Table 1 lists the PoE requirements for the Juniper Mist Access Points (APs).

Table 1: PoE Requirements for Juniper Mist APs
Generation Model Minimum PoE Required Wattage Required for Full Wi-Fi Functionality Notes
Wi-Fi 6E AP64 802.3af 13 W AP64 requires 802.3af power for full functionality.
AP45 Dynamic 29.3 W AP45 requires 802.3bt power for full functionality. On 802.3at power, it has dynamic functionality based on the configuration.

The AP can operate in 4×4 mode on any two data radios, or 2×2 mode on 2.4 GHz, 4×4 mode on 5 GHz, and 2×2 mode on 6 GHz with three data radios enabled. For example:

  • If you configure only two bands in the WLAN configuration, the AP operates in the 4×4 mode on both the data radios.

  • If you configure three bands in the WLAN configuration, then all three data radios are active. The AP operates in the 2x2 mode on 2.4 GHz, 4×4 mode on 5 GHz, and 2x2 mode on 6 GHz.

  • If you enable dual 5 GHz, then all three data radios are active. The AP operates in the 2×2 mode on 2.4 GHz, 4×4 mode on 5 GHz, and 2×2 mode on 6 GHz.

The dedicated scanning radio and BLE are always active regardless of power.
AP34 Dynamic 20.9 W AP34 requires 802.3at power for full functionality. You can use 802.3af power to connect to the Mist cloud but you'll see a warning message stating that the power is insufficient.
AP24 802.3af 13 W AP24 requires 802.3af power for full functionality.
Wi-Fi 6 AP63 802.3at 25.2 W  
AP43 802.3at 25.5 W  
AP33 802.3af 19.5 W AP33 requires 802.3at power for full functionality. However, the AP is capable of running on 802.3af power with reduced functionality as described below:

  • The 5-GHz radio operates in 2×2 mode instead of 4×4 mode.

  • The Eth0 port operates at a maximum speed of 1 Gbps.

  • The Eth1 port is disabled.
AP32 802.3af 19.5 W AP32 requires 802.3at power for full functionality. However, the AP is capable of running on 802.3af power with reduced functionality as described below:

  • The 5-GHz radio operates in 2×2 mode instead of 4×4 mode.

  • The Eth0 port operates at a maximum speed of 1 Gbps.

  • The Eth1 port is disabled.
AP12 802.3af 12.9 W AP12 requires 802.3at power only when you use the PoE out functionality. If you don't need to use PoE out, the AP can operate with full functionality using 802.3af power.
Wi-Fi 5 AP61 802.3at 19.5 W  
AP41 802.3at 19.5 W  
AP21 802.3af 12.9 W  
Other BT11 802.3af 5.5 W
