Which 8 Port Gigabit Switch Should We Purchase?

Our all-volunteer, IRS 501(c)(3) horse rescue charity (see: https://www.facebook.com/bhfer) is located in central Florida, home to 36 horses and the largest number of cloud to ground lightning strikes in the world.  We fried another Switch during a typical Florida afternoon thunderstorm today.  The Switch is plugged into a Panamax surge suppressor, which is plugged into an APC UPS, which is plugged into the house, which is connected to a whole-house surge suppressor.  And the whole thing is backed up by an industry-leading Generac fully Automatic 20KW standby generator.

The EMP from the Lightning seems to go through the whole house and fry the Switch--maybe because it has 8 Ethernet cables going to it.  Can anyone recommend (with Model Number) a bulletproof Switch for us?

It's not really a question of which switch to buy. The task is figuring out what's frying your equipment.

Are all of the cable runs located within one building?

I used to fry RS232 hubs in Tampa once a week when I had cables running between buildings.

I have no problem with 3-com (used to be HP Procurve) 8 port Gigabit switches. They are good, reliably and economically priced.

In a high lightning situations any copper wire will get the hit atleast one-time or other and there is no guarantee that something would work better over other.

The best way to handle this situation is using opto - isolators (like LCOM's LC -60601-1) on both the ends, this will not only protect the switches but also the equipment that is connected to those switches.

Instead if you looking for switching solution only and don't want to go thru the hassle of isolators then i would recommend redlion switches. They are built for IP67 standards to withstand rugged conditions.

For Don: The Ethernet cable from the barn is buried underground in 1" conduit.  Note that the networking function of the DVR got zapped too (as did a horse, still recovering).  This function is critical because that is how we view the cameras in barn on our computers in the office.  We are trying to get a new circuit board for the DVR (Eclipse GPR08).  But they want to install a new DVR at $95/hour.

For ambatihp: I sent both RedLion and L-Com a presales email but they have not answered.

So it looks like I go with 3-Com or Best Buy . . .

Any other advice or ideas?

3-com will be better than Best Buy which sells consumer stuff.

sorry I just gave lcom as example to get an idea on the solution.
Optoisolators are pretty common and you can get from cdw.com or blackbox.com

Here is the list (http://www.blackbox.com/Store/Results.aspx/Power/Opto-Isolators/n-4294958596) and same with the switches also. IP67/IP30 are the IEEE standards, there are of companies that provide those switches.

Like I said in my past comment, switch is not that important as they are available any where retail store that's around the corner and could be a quick fix if it frys.

What you would need to protect is the equipment that is fed from the switch, and that was the reason why i was more towards isolators than switch itself.

Since your are 501.c3, you could go to www.techsoup.org and request Cisco 3560-C's and 2 year warranty at a bargain.

Great Idea!  We buy our software from TechSoup.  I forgot about the hardware.
