PoE Status Information

Access points with the appropriate module enable detailed monitoring of the PoE power supply.

To do this, the access point reports the respective status via the CLI under Status > Hardware Info > Power, using several values. These can also be displayed in LANmonitor under the system information and interfaces of the access point.

PoE-Type (1.47.42.1)
Displays the connected PoE power source in a single line, rather than per port as in the "Ports" table. If two PoE power sources are connected, a string like "802.3bt-Type-3 + 802.3bt-Type-3" is displayed.
Ports (1.47.42.6)
The following information is displayed for each port of the access point:
PoE-in-Type
Indicates the type of power supply: 802.3af-Type-1-or-802.3at-Type-2, 802.3bt-Type-3, 802.3af-Type-1, 802.3at-Type-2, or no-PoE.
Note: The IEEE 802.3af Type 1 and IEEE 802.3at Type 2 types cannot be clearly distinguished and are therefore displayed as a single value.
PoE-in-Class
The class precisely specifies how much power (in watts) is available to the device. The following classes are possible: Class-0, Class-1, Class-2, Class-3, Class-4, Class-5, Class-6, Class-7, and Class-8. The class "None" is displayed when no PoE signal is present.
LLDP-Power-Negotiation
In addition to class-based negotiation, LLDP negotiation is also available at a higher level. This allows the PD (the access point) and the PSE (Power Source Equipment, the switch) to negotiate power in watts more granularly. This is optional and is not performed by all switches. If used, the expected behavior is that the switch initially activates only PoE in IEEE 802.3af Class-0 or similar (i.e., very low power), and higher power is activated only through LLDP negotiation with the access point. In this case, type and class will remain at a low level, but the actual negotiated power can be seen in "PoE-Power-Allocated-W".
Note: Please note that "PoE-Power-Allocated-W" always shows the maximum of class-based and LLDP-based negotiation. Therefore, if LLDP is absent but Class-6 was negotiated, 51W will be shown.
Device-Functions (1.47.42.7)
WLAN-Streams-2.4GHz
Indicates the possible WLAN streams in the 2.4 GHz band: Off, One, Two, Three, or Four.
WLAN-Streams-5GHz
Indicates the possible WLAN streams in the 5 GHz band: Off, One, Two, Three, or Four.
WLAN-Streams-6GHz
Indicates the possible WLAN streams in the 6 GHz band: Off, One, Two, Three, or Four.
WLAN-Scan-Radio
Indicates whether the scan radio is active.
USB-Port
Indicates whether the USB port is active.
Failover-Status (1.47.42.10)
The following statuses are possible:
Ready
If both PoE sources are active according to IEEE 802.3bt, it waits for a failover condition to occur, such as power loss on one of the two cables.
Engaged
A failover condition has been met, and the access point is now in failover status.
Disabled
Failover function has been disabled in settings, as "Load-Sharing" is configured instead of "Failover".
Power-Status (1.47.42.11)
Indicates whether the access point has enough power to enable all functions, such as all WiFi radios, USB, etc. ("Fully operational"). If insufficient power is available, the value "Reduced function set" is displayed. You can check the "Device-Functions" table to see which functions are specifically disabled.
Dual-PoE-Mode (1.47.42.12)
The configured mode.
Hitless Failover
Allows uninterrupted operation of the access point if the PoE supply fails on one of the two Ethernet ports. The access point will not restart. This mode requires that the same PoE power is provided on both Ethernet ports.
Note: In the case of the LX-7500, IEEE 802.3bt (Class 6 / 51W) is required for full operation.
Load Balancing
The access point draws power simultaneously via PoE from both Ethernet ports. Usually, the power drawn from both ports is similar, but ultimately this is influenced by the applied voltage and is therefore dependent on the specific circumstances.
Note: This enables full operation of the LANCOM LX-7500 with 2x IEEE 802.3at (Class 4 / 25.5W).
