Hey AFRIK-IT and DEVEL-L'ers!
It's been some time since I last posted, so I should let you know that I've
abandoned the ivy covered halls of the University of Iowa and taken up
residence at the University of Jos in central Nigeria. We're constructing
a WAN and setting up an Intranet (cargo culting in anticipation of a real
Internet connection...) and running into serious power protection problems.
It turns out that the city of Jos was once listed in the Guiness Book of
World Records as being host to the most lightning strikes. On top of that,
our electricity disappears several times a day. Finally, and
unfortunately, our wiring isn't all we could hope for.
All of this adds up to large piles of expired equipment (modems and
monitors seem particularly hard hit) and users who are leery to plug in and
Of course, there are a large number of UPSs around here, but not enough to
handle all the computers and network hubs. These too are vulnerable to
surges and get fried pretty regularly.
Shipping new equipment to Jos essentially doubles (even triples) the
original cost of the equipment (especially in the case of the UPSs).
So I'm looking for information on home-grown power protection. Is it
possible to couple a UPS with a larger battery to handle a larger amount of
computers? (We have two classrooms with 30 computers each.) What are
other solutions you've found to protect your power, data, and telecomm
lines from surges and lighting? How about building-wide power protection?
Classroom power protection and conditioning?
Any and all info would be greatly appreciated.
I should mention that I've got a copy of the PolyPhaser web site
(www.polyphaser.com) as well as their very informative book, "The 'Grounds'
for Lightning Protection."
If you have Web sites for me to explore, please send the pertinent pages or
the URLs. We do not have Internet access, but I have a grad student in
Iowa who can grab the Web site and burn it onto a CD for me. (Called
