WAX-650S PoE on older Nedula switches

flottmedia

We currently have two WAX-650S connected to a GS-1920-24HP. The switch ports are set to "Power up mode" =802.3at. Is it safe to set the APs to "Force override the power mode to full power" in order to get rid of the limited power notice if only two APs are connected to that switch? At least it seems to be working and the actually cunsumed PoE power is far below 30W ...

Hi @flottmedia:

Just like you observed, when the client number is not so many with normal data traffic, the power consumption of WAX650S is usually below 30W during runtime. Only when there're many wireless clients generating huge data traffic, the power requirement could reach beyond 802.3at capability. So you can try to observe if the power consumption is beyond 30W during the busy time in your network, and accordingly decide whether to enable this feature or not.

There's another discussion thread about this topic, which includes detail introduction of AP's power behavior under different configurations. Welcome to refer to it for more information.

Thanks, @Zyxel_Richard, I used the search before my post, but didn't come across the other (very helpful) post. We currently observe a PoE power of around 10 to 12 from both APs on the switch. Do you have an estimate number of clients causing a power consumption > 30 W (leading to a reboot of the APs in that non BT-Setting) when "Force override the power mode to full power" is enabled?

Hi @flottmedia

The AP's power consumption is decided by many factors, such as output power settings, data traffic amount, client type, amount and environment condition. So we don't guarantee the AP definitely won't reboot when connecting clients is under given value. In this case "Force override the power setting" is more like a workaround to let users enjoy the full-power mode performance before they upgrading the PoE switch to 802.3bt support. Meanwhile they also need to know the risk of power overdraw when enabling this function.
