I just moved into a Lennar home and there were three WAPs that look like this in the home: (picture link). I connected one to a new internet switch (model number TP-Link TL-SG105) and also connected my modem to the switch. I'm not seeing power go to the WAP via the power over ethernet cable. What else must I do to power the WAP? I tried to factory reset the unit, but I did not see any indicator lights. Please assist with this request; any installation or initialization steps would be appreciated. Thank you!
