Hello,
We have a couple of 411GL boards connected with:
TP-POE-24G injectors
http://www.wlan1.com/product_p/tp-poe-24g.htm
Whenever we connect these injectors to our gig switch we get input and crc errors on the switchport. This is after 20 seconds of traffic:
GigabitEthernet0/45 is up, line protocol is up (connected)

We have a ton of 411AH boards with no issues. Has anyone else see these problems with the 411GL's?
Switches are Cisco 3560G. If we change the injector to a 100M injector then the errors are a lot less, but not completely gone. This issue has been verified on multiple switches with different routerboards. All have been upgraded to the latest version 5.24 along with the latest firmware 3.x
Thanks,
Dan.
