Ethernet Switch(s) locking up
Posted on 2006-06-21
We've been having an issue with a switch at a specific location on site, locking up seemingly at random.
The switch has been replaced several times and the problem persists, so we're fairly certain it isn't a hardware issue.
The power has been routed to a UPS, which has also been swapped out, so we're fair certain it is not a power fluctuation issue.
Which leaves either invalid line voltage or invalid frames.
Neither of which we have a simple method to test for.
Does anyone know of a tool, handheld and portable if possible, that can test for either of those conditions.
I'd like to say money is no object, but... well, let's stick with a $300 price cap if possible.
(kind of an off the cuff price, but really, higher than that and we might as well replace the switch with a managed one that should ignore invalid voltage or frames)
