of the school organizer's first tasks is to arrange for a site survey.
The lead technician conducts a walk-through visit to the school site,
accompanied by the school organizer and the site administrator. You
should also invite the facilities manager or chief engineer for the
school or district. The purpose of the survey is to assess the site
for any obstacles to running cable and to decide where the cable
runs should go.
are the concerns to address in the site survey.
- The NetDay objective
is to wire six classrooms to one central point (as shown in
our sample wiring plan). You may want to concentrate your efforts
on key facilities (the library, administration building, computer
labs) and then consider which classrooms to wire. Assign priorities
in case you run out of cable.
NetDay kit allows for two "drops" (where jacks
are wired to the cable to provide network outlets)
per classroom. Two or more drops per classroom
make it much easier to determine the source of
any problem that may arise.

After the site survey,
the technician maps out the cable runs in the wiring plan. If
accurate, architectural computer-aided design (CAD) floor plans
exist for the school site, we recommend using them to draw up
the wiring plan, so that you can easily estimate the amount of
cable you will need. Otherwise, you will have to measure each
run. It may speed things up when you're measuring to remember
that ceiling tiles are 2 feet square. Don't forget to allow for
the distance from the ceiling to the drops, and follow the rules
for allowing slack in the NetDay Cable Installation Guide.
plan for NetDay was to wire five classrooms and a library.
In fact, we did 10 classrooms and a three-room library in
one afternoon with 80 volunteers, and we installed about
5,500 feet of cable. We've already had NetDay II, wiring
an additional 22 classrooms with another 6,500 feet of cable.
Things went like clockwork. . . . I wouldn't have missed
NetDay for anything."
