[Misc] Intermittent LAN failure TA 5500i

[Guest]

Hello all,
We just acquired a 5500i and it appears to lose LAN connection periodically. The status lights on the LAN port go out and it loses connection to our network. The port isn't powered and was previously used for 3 years by a TA520i with no problem. Has anyone else experienced this or have a solution? Thanks in advance.

try forcing it to a lesser connect speed than whatever it's negotiating via auto... try a half-duplex mode too, that eliminates one of the pairs in the cable if there's a bad pair, it will either fail to connect, or connect better. punch blocks in the wall and rack can be fickle depending on many factors including the passage of time

Thanks sparky, I changed the speed from auto negotiate to half duplex and we haven't had any more problems today. Thanks for the excellent solution.

I had (6) CS-5050's all in the same building dropping off the network. It seemed random at first, but once I had pulled all the reports I discovered that they typically dropped off around 5:00am each morning, and jumped back on around 3:30pm each afternoon. The power quality analyzer confirmed what I kinda already knew.

Each morning the first task was to unload flatbed tractor trailers with this huge electronic crane. The clue came a few days later. No shipments to unload and not network loss. =^..^=
