point connection.
Information received will follow a path
through a Cisco ASA firewall, into a St.
Bernard
iPrism

-
3100 inline content filter
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.

Individual LAN’s


Within each building
is a Cisco 3560 Layer
3 switch which
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
Supply (UPS) which
protect the servers in
the event of a power
outage.

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replacing outdated servers with newer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.
