--- TIC-TECH message:
Drew,
Thanks for the timely update to your previous post about these great
sounding (and inexpensive) switches. I have three questions: one
technical, one procedural, and one organizational. I hope anyone who
has info will jump in here:
1) I assume it would benefit the performance of the 11 computers in my
classroom, all currently connected to the network through a 10 baseT hub
in my room, to replace that hub with one of these AT switches - right?
2) If there would indeed be a performance upgrade with this switch, how
would one go about purchasing it with funds other than building/district
dollars? Like, how can I buy one?
3) Who in the world is going to supervise, oversee, recommend, etc. the
purchase and installation of these for my school? Our building is
slated for wiring next summer. The levy does not pay for this stuff,
nor does it pay for someone in my building to work the problem. Who
will be in charge of this?
Thanks in advance to anyone for answers to any of the above - Mark
