Axis camera-Garrett Fiber switch-cisco switch

We have a Axis camera that plugs into a transitions network fiber/ethernet converter..powered by POE injector, this goes down to a Garrett fiber switch then is uplinked to a Cisco 3750 switch via ethernet.

We have several other cameras in this configuration and everything works great with them.

I have this one camera Axis..that when I plug it in it causes the other cameras network to get sporadic and the axis camera itself never comes online. I can plug the camera in straight POE to a POE switch and it works great. I have verified the Transistions Fiber>Ethernet converter is ok and so is the POE injector.

So when I plug it in..the other cameras get sporadic (pings start timing out) but the pings to the Garrett uplink port are flawless.

Anyone have any suggestions?
No errors on the cisco switch.
I Don't know much about the garrett to troubleshoot it,but all the other cams work great.

At a guess, the "problematic" Axis camera is doing "something it shouldn't".

As you have a 3750, I would configure a span/monitor port on the 3750 and connect the Axis camera (via its PoE injector) to the 3750 and use a packet sniffer such as Wireshark to see what is coming out of the Axis Camera.

Whats strange is the garrett switch has a spare ethernet port on it and when I plug the camera into the ethernet port on the garrett it works like a dream.

It seems to be a combo of the fiber/ethernet converter and POE injector.

Do the cameras have static IP's assigned or are they using DHCP?  It sounds like a possible IP conflict.

Static IP's.

I'd change the IP on the troublesome camera to one you know isn't in use, just to rule out an IP conflict.  If the error persists, then the camera's built in NIC may be bad.  Can you test the camera on an isolated test network switch?

camera works great with the static IP when plugged in straight Ethernet to the Garrett Switch.
Seems to be the combo of the fiber>ethernet converter and POE injector..

Though I have tested those both stand alone and they seem to be fine.
