I can't find it! [Feb. 4th, 2009|10:07 pm]
I can't find it because I don't know what I'm looking for!

In general:

A box! An Ethernet box!
The general idea is a solution to a problem.
The setup of our hubs in work enables any one to blow-up, and we can route around them.
The one remaining problem is, there's lots of devices routed to a single hub. This is the Achilles heal. If it fails, we've lost everything connected to it. (Quite a bit!)

I thought of wiring some Cat-5 cable in the shape of a Y ... the bottom of the Y would connect into the devices, and the two top branches would plug into two hubs.
One hub would be on, and the other hub would be off. If the hub that's running fails, you switch it off, and turn the other one on.

In theory I'd be shot. In practice - it could work!

Then I realised there's probably something electronic that can do this, and I imagined a box like the one below...

|  [ ]  [ ]  [ ]  |    < Output bank 1 to primary hub.
|  [ ]  [ ]  [ ]  |    < Ethernet Cat5 inputs from equipment. (PC's, printers, etc)
|  [ ]  [ ]  [ ]  |    < Output bank 2 to secondary hub.

You can swap between the two outputs by passing it some sort of signal (from a hub somewhere else ;) )

Do these things exist? If they do, what are they called, and if they don't what do you think the possibility of making them is?
