then through a Cisco 3825 Router which
receives information from two buildings
connected through a T1. Before incoming
data leaves the MDF it goes through a Cisco
Catalyst 3550 with fiber core which
distributes the information to the correct
building. All fiber is multimode for shorter
distances.

serves as the building
core
This allows for each
node (client machine,
printer, etc.) in the
building to connect
back to the WAN
Servers
Servers have their own
connection to the WAN.
All servers are also
connected to a
Uninterruptible Power

Number of Nodes
Within the last year the district has cut
the number of servers from 60 to 44 by
replacing outdated servers with newer
technology which has increased storage
capacity.
The district also has approximately 650
nodes; this includes lab computers,
teacher computers, printers and various
other peripheral hardware.
Summary
The network is a critical part of the district.
It allows sharing of information, access to
student learning programs, storage of data,
access to teacher programs such as
gradebook and attendance, managerial and
business applications, location of district
websites including online tutorials and
Intranet and allows parents to connect to
teachers as well as staying up to date on
student progress.
