The PoE output needs to be configured on the Switch port side typically. Our AP will recognize the 802.3af or at, and power 2.5g Eth ports / more wireless radio streams, etc.
Here are some general PoE troubleshooting guidelines if this is helpful.
Basic POE troubleshooting
- Check whether the Ethernet cable is connected to the proper PoE port of the AP or not. Is it rated correctly for distance between switch/AP (Cat5/5e, Cat6/6a)?
- Try another port on the switch.
- Try a different cable if possible. Check the cable ends for damage, corrosion, etc.
- Check the switch configuration to ensure POE of the proper type is enabled. [ 802.3af (802.3at Type1 'PoE'), 802.3 at (802.3at Type2 'PoE+') ].
- Check the switch which you are using has PoE option or not. Also check the specific Ethernet port. Some of the switches will have PoE enabled for some specific Ethernet ports only.
- If practical, try another AP on the same switch port. If it powers up, first AP may have a bad AP PoE port (RMA).
- When multiple APs are connected to the PoE switch, Keep an eye on the PoE budget also. If the PoE budget of the switch is exceeded then the AP(s) will not get power from the Switch.
- Check whether the PoE output specification of the switch is compatible with the AP's PoE port or not, for example 802.3 af / 802.3at.
Note: These guidelines relate to all manufacturer PoE switches (not just ICX) and Ruckus APs.
The R720 Quick Start Guide describes either 802.3at or 803.af PoE, but no 802.3bt support.https://support.ruckuswireless.com/documents/1788-ruckus-wireless-r720-quick-setup-guide
