I need for a special application a very reliable link between two networks (2 switches). And for this reason i need to put two separate uplink cables (two "different routres"). I tried this configuration using two AlliedTelesyn unmanaged 10/100 switches, but the result was as i expected, the traffic on the two links has increased instantaneously, and the two switch was unusable, until i disconnect, one of the links and power off both switches :(

Any usable solution ?

Does the application allow for some switching time, or does it need any re-routing to be tranparent? I'm not quite convinced the most vulnerable part of the setup is the cable... unless it is running between buildings possibly. Other safety measures perhaps already taken but not mentioned (e.g. switches and computers on UPS).

szjozsef,

You can use managed switches with tranking (link aggregation) capabilities. Using 2, 3, 4, etc. cables you will get very reliable connection and increased bandwidth between switches.

Do you know if your switches support Spanning Tree?  If so, the downtime could be due to that and they will start to work again after a minute.  If they do not, there is no way to link the two without adding another piece of equipment.  My suggestion would be to try again and see if it works after a minute.  If not, you will want to think about buying some new equipment.

szjozsef,

I can recommend you following 3Com Switches:
- SuperStack 3 Switch 4300 (48x10/100 + 1-4x100/1000Base-x),
- SuperStack 3 Switch 4400 (24x10/100 + 1-2x100/1000Base-x),
- SuperStack 3 Switch 4400 SE (light version of 4400).
For additional reliability you can use it with 3Com Advanced Redundunt Power System (ARPS).

Also you can use Gigabit Switches SS 3 4900 (12x1000Base-T), 4900SX (12x1000Base-SX), 4924 (24x1000Base-T), 4950 (12x1000Base-T, 6x1000Base-SX, 6xGBIC). All of these swithes have slot for additional 4-port 1000Base-x module).

Could you provide me detailed description of your network?

Sounds like a spanning tree problem.
