Sean - I moved your message to a new topic as it wasn't directly related to the other topic.
What are the radios you're trying to connect (model numbers)? What surge supressors are you using with these? Only the C000000L033A will allow Gigabit negotiation. The radios must be left on "Auto Negotiation". How long are the cable runs?
CMM3/4 are only 100mbit, if your not using CMM, any your having that issue, your LPU's probably aren't designed for gigabit canopy, the way canopies do their timing means they do their power differently, thats why you need a CMM5 or packetflux gigabit to get 1gbit lpu protection to my knowledge, don't think just any generatic lpu will work let alone 2 of them.
