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 Ali Kujoory 7/3/2015 2

Six Racks in the Lab, one per Station Rack 1 Rack 2 Patch Panel Xyplex Terminal Ali Kujoory 3/3/2021 3

Asante Hub & Cisco Switch • One Asante AH 2072 • Simply connect computers & devices together • Have twelve 10 Base-T ports – Ethernet over twisted pair • Make sure the lights up when you plug-in an Ethernet cable Ali Kujoory • Two Cisco Switches 2900 per station • Switch connections between computers & devices • 24 X 10 Base-T ports on each switch • Cisco switches 2900 were replaced by Cisco 3500 XL 3/3/2021 4

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 3/3/2021 5

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. Ali Kujoory Xyplex MAXserver 1600 • The Xyplex terminals in stations 4, 5, & 6 are served by the Xyplex MAXserver in the corresponding patch panel in the back of the room. 3/3/2021 7

Ethernet over Twisted Pair • Early Ethernet cabling had generally been based on various grades of coaxial cable – Costly, difficult to work with, . . • In 1984 Star. LAN/AT&T showed simple Unshielded Twisted Pair (UTP) by using Cat 3 cable Ethernet UTP Cable with RJ 45/8 P 8 C plug – Same simple cable used for telephony • This led to the development of 10 BASE-T & its successors • These standards use RJ 45 / 8 P 8 C connectors • Cables went from Cat 3 to Cat 7 – 10/100 BASE-TX & 1000 BASE-T, supporting speeds of 10, 100 Mbit/s & 10 Gb/s – All support full-duplex communication – BASE = baseband, T = twisted pair – 1 & 10 Gbit have four pairs of wires – 10 BASE-T & 100 BASE-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 Ali Kujoory 3/3/2021 9
