Networking Lab Layout In Salazar 2006
• Six Stations
• Four computers per station for
a total of 24 students
– Computers have multi OSs
• Windows & Ubuntu (Linux )
• Two racks per station
containing various equipment
– Patch panels, power supplies,
switches, routers
• Two additional racks at the
back devoted to devices &
servers shared by entire lab
– For addressing & configuration
• Cabinet in front contains a
computer for lecturing

Asante Hub & Cisco Switch
• One Asante AH2072
• Simply connect computers &
devices together
• Have twelve 10Base-T ports
– Ethernet over twisted pair
• Make sure the light lights up
when you plug-in an Ethernet
cable
Ali Kujoory
• Two Cisco Switches 2900 per
station
• Switch connections between
computers & devices
• 24 X 10Base-T ports on each
switch
• Cisco switches 2900 were
replaced by Cisco 3500 XL

Cisco Catalyst 3500 Series XL
• Is stackable 24 X 10/100 Mbit &
1 Gbit Ethernet switches
• Delivers premium performance,
manageability, & flexibility
• Provides interconnected
switches with an independent
high-speed stack bus that
preserves valuable desktop
ports
• Up to sixteen 24-port switches
can be stacked to provide 380
Ethernet ports
Ali Kujoory
• Allows management of all
switched ports from a single IP
address
• Can be easily managed via the
Cisco Network Assistant, an
easy-to-use, GUI based
management tool

Patch Panel
• Ports at the top of the patch panel are connected to the ports of each
computer in each station.
– To connect the computers & other devices together.
─ Port 0 of each
computer is
connected to the
production
network in the
campus &
Internet.
─ Port 1 of each
computer is also
connected to the
server at the back.
─ Ports 2 & 3 can be
used to make
networks in the
lab.

Xyplex Terminals & Servers
• Xyplex MAXserver 1600 is a
terminal server allowing access
– The console ports of various
network devices from remote
computers
• In each rack in front there is a
Xyplex terminal in the patch
panel connected to the console
of hubs, switches, & routers in
that station.
• The Xyplex terminals in stations
1, 2, & 3 are served by the
Xyplex MAXserver in the
corresponding patch panel in
the back of the room.

Xyplex MAXserver in the
corresponding patch panel in
the back of the room.

Ethernet over Twisted Pair
• Early Ethernet cabling had
generally been based on various
grades of coaxial cable
– Costly, difficult to work with, ..
• In 1984 StarLAN/AT&T showed
simple Unshielded Twisted Pair
(UTP) by using Cat3 cable
Ethernet UTP Cable with RJ45/8P8C plug
– Same simple cable used for telephony
• This led to the development of
10BASE-T & its successors
• These standards use RJ45 / 8P8C
connectors
• Cables went from Cat3 to Cat7
– 10/100BASE-TX & 1000BASE-T,
supporting speeds of 10, 100 Mbit/s
& 1 & 10 Gb/s
– All support full-duplex communication
– BASE = baseband, T = twisted pair
– 1 & 10 Gbit have four pairs of wires
– 10BASE-T & 100BASE-TX only require
two of the pairs
- Most common - 10/100 & 1000 BASE-T
Cat 6
- 250 MHz can go to 100 m
• Based on IEEE 802.3 standards
