N2024P POE issue
I replaced an older POE switch with a new Dell N2024P. The Switch had three Cisco LAP1242G Access Points connected them.
After connecting the access points to the new switch they were all in a Disabled state due to low power. When I ran a show power inline on the switch the three ports showed a draw of 3300 mw.
I had to go change each of the switch ports to power inline high and change the priority to critical and change the remainderof the ports to power inline never.
On the access points I changed the Power Injector Selection to installed.
The N2024P would not supply the necessary power for the access points after the changes. I had to reset the APs 3 times before the switch would provide the 5000mw to run the APs.
Sp I would change the port settings; inline power high and critical. Power injector Selection to installed on the AP and then reset the APs three times and the switch would provide 5000mw.
As stated the switch is a N2024P running firmware 6.1.0.6.
Why would the switch not provide 5 watts out of the box for these access points?
Is it a known issue?
Did I do the correct workaround?
I would like to know why I had so many issues getting this switch to provide the correct power for these access points.
