AP WAX630E PoE++ injector or switch
Hi all,
can anyone advise me on whitch PoE switch or injector would be suitable for WAX630E?
I just get YuanLey Gigabit 60W, PoE++ Injector but it seams that it dose not work.
I notece that on the website is indicated 27.64W. In the user manual it is indicated 60W. See attachment.
Whitch is right?
Thanks.

Jakicevic, Yes you have to use a 60watt or greater switch. I found a switch by a company Linovision. 8 PoE ports. 4 are 90watts and the other 4 are 30watts. I saw the data sheet and I read what you read 27.4 watts. When i plugged my WAX630E in the 30watt PoE port, it would not come on. It dose work in the 90 watt port. The only thing the switch isn't a managed switch. I wrote the company Linovision asking them to come up with a manage switch with the same port configurations and they said they are working on it. Netgear has one the 4350 but it's to exspensive.
With any PoE device requesting IEEE802.3bt, it won't be powered from a switch PoE port supporting IEEE802.3af/at only, despite the device seems to offer 30 W. It's mute to think about bulbs and AC power, we talk of industry standard PoE here.
Peek and poke over the Linovision offerings, shows eg. a switch with these specs:
- Port 1-4 supports IEEE802.3af/at/bt 90W PoE (Power over Ethernet), port 5-8 supports IEEE802.3af/at 30W PoE
Very obvious why the WAX630E won't and can't be powered from what is specified as a IEEE802.3af/at 30W PoE port. It's a strict handshake between PD (Powered Service) and PSE (Power Source Equipment). Forget about what you learnt at school about electricity. Unrelated to Netgear...
The 802.3bt standard does describe these common type classes.
802.3bt Type 3, 4PPoE aka PoE++, 60W at the PSE, 51W available at the PD
802.3bt Type 4, 4PPoE aka PoE++, 90W at the PSE, 71W available at the PD.
Off the fixed Types, implementations 802.3bt (based on LLDP, not using Type signals) exist with
30W at the PSE, 25.5W available at the PD
45W at the PSE, 40W available at the PD
75W at the PSE, 62W available at the PD
PSE: Power Source Equipment
PD: Powered Device
What Netgear shows with 60W is the minimum standard 802.3bt Type 3 variant, not the effective requested and drawn power. Some PSE design inherit strict type based power allocation and reservation, the flexible variant is more common in the 802.3bt PoE++ PSE switches. For the effective numbers, please consult the WAX630E Data Sheet.
The current drawn by the PD during classification is called the classification signature or classification current. The IEEE PoE specification defines five classifications signatures the PD is allowed to draw during classification.
As such, enabling a PoE power delivery is a multi-stages process. Variations can exist with the different vendors, where the negotiation can be not successful - something to check with the vendors involved.
As we are not shure what product can be compatible with yours can you please indicate the vendor/product that can be sure that is compatible with your device?
Switch and injector.
Can we use POE+ 802.3AT switch or injector as well or not?
Thanks.
Netgear has several switch models properly supporting the required power IEEE 802.3bt, and at least 2.5 GbE links, like the unmanaged MS108UP (not allowing multiple VLANs and independent SSID), the Plus managed MS108EUP, and on the higher end of the product lines the fully managed M4350 Managed Switches 1G to 25G for AV over IP and IT
These are not my devices ... I'm just yet another Netgear customer.
802.3at does only support Type 2, so max 30W at the PSE resp. 25.5W at the PD what is not sufficient for the WAX630 or WAX630E (without reducing capabilities or power). Keep in mind that most 802.3at devices are supporting 1 GbE only.
