X-BeenThere: freebsd-net@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Networking and TCP/IP with FreeBSD List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 13 Mar 2006 08:57:38 -0000 I'm currently planning renovations for the power mains supplying are server room. One of the ideas I have is to float the entire room using a isolation transformer. The only problem to this solution, that I can think of, is that all of the equipment that's attached to the other end of the Ethernet cabling won't be isolated, the NIC cards do have 1:1 transformer coupling for the wire pairs but... In the event of power surges, spikes, brownouts, and/or nearby lighting strikes I feel that It's conceivable for there to be a large voltage differential on the wires that could damage the equipment on ether end of the wire. Are there any easy (cheap) work arounds to this problem, will those RJ45 network surge protectors work.... Or am I completely off base in thinking that this would be a problem? -- BSD Podcasts @ http://bsdtalk.blogspot.com/
