I am wishing to convert a 750n from Homeplug to PoE. Using Homeplug, the system works excellently. I am not able to connect to the camera using PoE.
My process has been:
- Plug the 750n into the same Ethernet port on my PoE router that the Homeplug base was plugged into
- Wait for the 750n to display power indicators
- Insert a paperclip to reset the device, about 10 seconds until the 750n blinks light blue
- Disable my laptop's Windows Firewall and Kaspersky protection
- Launch LogitectAlert Commander (patched to 3.2.181 as of 7/13/2012 )
- I get the following error message window titled "Firewall and Filter Warning":
Traffic Types Blocked:
XMPP, TCP, UDP Point-to-Point
- No cameras are found on the system
My question is, why does the Homeplug work flawlessly, plugged into the same port, but when I switch to PoE, I get this message?
Thank you for your assistance.

It really should be very simple...just moving the camera ethernet cable from the homeplug adapter to a PoE port on the switch/router...no resets, etc. What router do you have ? ( a PoE router is rare ). How is the PC connected to that router ?

Thank you for your assistance. We are connecting to a Cisco SGE2010P Switch. This is a 48 Port PoE Managed Switch.
We have multiple VLANs on this 1GB switch. I have tried setting the Port to 100 MB (which it autonegotiates to if I leave it at 1GZB) and I have set the port to both Access on the correct VLAN, as well as Trunk (just to see if the Logitech Alert camera could determine the VLAN to use).
In all cases, the camera boots, pausing for about 30 seconds with a while light, then blinks light blue and finally reboots.
HOWEVER, when I introduce an unmanaged (dumb) switch in between the PoE switch and the Camera (and I also use a PoE power injector) the camera has no problem what so ever getting an IP and connecting to the Logitech Alert Commander software.
I tried multiple unmanaged switches and I used different SGE2010P's (we have several) and the results are always the same. We have hundreds of other devices connected to these PoE's and none have DHCP problems, but it seems when direct connected to the SGE2010P switch, the Logitech Alert Camera (750n in this case) has no ability to resolve an IP over DHCP. I tested by directly connecting the camera to the SGE2010P that the computer hosting the Logitech Alert Commander software was on, but that made no difference. The only time it worked was when an unmanaged switch was introduced.
DHCP is provided by a Cisco Router the SGE2010P's are connected to and I have made no changes to the router configuration during any of this testing.

Unfortunately I'm no help with commercial/managed networking...obviously not a PoE issue, but something simple in the switch config I'm sure...maybe there are some networking guru's or Logitech Engineers here that know the key to the issue.
