Hi

I have a client with a network with a 24 D-Link switch connecting to 4 other 5 port switche's with all PC's connected to UPS's and 2 other industrial machines connecting to the network with cat 5 and network cards.

every time there is a power spike or dip the network locks up and we have to shut down most of the switches, server and pc's to get it up and running again.

any ideas ??

Hello,

Sounds like your UPS units need to be replaced.

Power spikes can do that to electronics easily enough. I agree with the above in that you may need to at least test out another UPS.

How will I be sure that the UPS's is working?

                                The network is running Fix IP and even then it takes a while to come up after resetting the server and switches, and I have alredy swopt out the main switch and UPS, I am swopping the rest of the switches today as well as testing the cables with a Fluke tester.

Are all the servers, switches plugged directly into the UPS?

Thanks for the info.  I personally wouldn't use that model in a server environment.  I would consider a different model to support your current and future needs but that depends on the budget. Here is an example- http://www.apc.com/products/family/index.cfm?id=165
