Power up E501s Ap with cnMatrix EX2028-P

Thanks, and no problem.  That's what we are here for.

If you use the POE out on the E501S, it will require POE+ (802.3at) to power on.  Assuming worst case scenario, that would be 26W drawn per E501S that has POE out enabled.  I seem to have attached an older spec sheet last time, so I've attached the newest.

26W x 10 E501S's with cameras = 260W

13W x 8E501S's without cameras = 104W

Total Draw = 260W + 104W = 364W, which should still be okay for the 400W max draw.

I would configure priority for the E501S's with cameras to ensure proper POE+ functionality.

These links should help with the VLANs.  Essentially you would configure the E501S Ethernet ports with the appropriate VLAN information.  Most likely this would be a single access port VLAN for the ETH2 port (to camera) and then a trunk port for the ETH1 port (main Ethernet), with the management, camera, and any other VLANs configured in the membership table.  Attached is an example from my E-Series.
