Wireless Access

Hi,

The recommended POE power for AP515 Wifi 6 is 802.3bt (class 5). But if it doesn't get that power its works with restrictions, what are those restrictions or features it looses?

Thanks,

Aamir

This datasheet should answer your questions. Refer to Page 5.

thanks i saw that but it still doesn't specify what restrictions it will apply?

If only 802.3af can be supplied then Intelligent Power Monitoring (IPM) must be enabled. IPM allows you to specify the order in which features would be disabled.

For example you'd want the USB port to be disabled first typically (unless you need it...). As stated, you specify the order. Here are some of the things you might use:

cpu_throttle_25 Reduce CPU frequency to 25%

cpu_throttle_50 Reduce CPU frequency to 50%

cpu_throttle_75 Reduce CPU frequency to 75%

disable_alt_eth Disable 2nd Ethernet port

disable_pse Disable PSE

disable_usb Disable USB

radio_2ghz_chain_1x1 Reduce 2GHz chains to 1x1

radio_2ghz_chain_2x2 Reduce 2GHz chains to 2x2

radio_2ghz_chain_3x3 Reduce 2GHz chains to 3x3

radio_2ghz_power_3dB Reduce 2GHz radio power by 3dB from maximum

radio_2ghz_power_6dB Reduce 2GHz radio power by 6dB from maximum

radio_5ghz_chain_1x1 Reduce 5GHz chains to 1x1

radio_5ghz_chain_2x2 Reduce 5GHz chains to 2x2

radio_5ghz_chain_3x3 Reduce 5GHz chains to 3x3

radio_5ghz_power_3dB Reduce 5GHz radio power by 3dB from maximum

radio_5ghz_power_6dB Reduce 5GHz radio power by 6dB from maximum

Useful resources depending on whether you're using Instant or Campus APs:

Maximum worst case power consumption for the 515 as per the data sheet is:

PoE powered (802.3af, IPM enabled): 13.5W

PoE powered (802.3at/bt): 20.8W

When powered by DC or 802.3at (class 4) / 802.3bt (class 5) PoE, the AP will operate without restrictions.

When powered by 802.3af (class 3) PoE and with the IPM feature enabled, the AP will start up in unrestricted mode, but it may apply restrictions depending on the PoE budget and actual power. What IPM restrictions to apply, and in what order, is programmable.

Operating the AP with an 802.3af (class 3 or lower) PoE source and IPM disabled is not supported.
