PoE configurable power modes

Passive 24V mode

Passive 24V mode is a Cambium-specific implementation of passive PoE to function at 24V, as oppose to

standard 802.3 PoE which delivers power at 54V. In this mode, no detection or classification is

performed. 24V is forced on the port.

Note that the voltage output range from cnMatrix is 22V to 26V.

For this mode, the PoE LED will light up green. For standard 802.3bt mode, the PoE LED will light up

amber.

Note

Passive 24V mode is only available on ports 9-16 of TX2020R-P or TX2028RF-P

and ports 5-8 of TX2012R-P.

Caution

Passive 24V mode may cause damage to devices since it automatically puts

power on the line. Check that a device is compatible with this passive power

mode before using it.
