Simple rule, make sure that you're upstream and the down-stream end has more bandwidth than the up-stream end. It's kind of the reverse of the internet. In the event that the inflow exceeds the outflow, hit the SCRAM switch before you fry something. This is the main reason I have it (SCRAM), but I'm damned if I can justify it for that reason. It's a lot easier to talk about fire. It should be left in the Fire codes. What are the four seasons in California? Earthquake, Drought, Fire, and Flood. You've no doubt heard about the "Oakland Hills Fire" but no one has ever talked about the mud-slides, in the Winter following the "Oakland Hills Fire", caused by the ground-cover being burnt off. In fact, no one hears much about California flooding. That's because it is a natural part of the ecology here and not as sexy as earthquakes and brush fires. > -----Original Message----- > From: Sean Donelan [mailto:[email protected]] > Sent: Sunday, November 05, 2000 8:58 PM > To: [email protected] > Cc: [email protected] > Subject: Re: Fire protection in ISPs and collocation facilities > > > > On Sun, 05 November 2000, Marshall Eubanks wrote: > > In Fairfax and Loudon Counties here in Virginia, fire codes require > > water for fire suppression (you can use other means, but you have to > > have water).
