Networking Lab Layout In Salazar 2006 Six work areas: 1 - 6 Four computers per work area for a total of 24 students. Computers have multi OSes Windows & Ubuntu (Linux). Two racks per work area containing various equipment. Patch panels, hubs, switches, routers, power supplies. 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.

Six Racks in the Lab, one per work area Patch Panel Top Alcatel OS6860 Asante AH2072 Cisco 3500 Bottom Cisco 2600 Top Cisco 2600 Bottom Alcatel OS6860 Alcatel OS6450-10 Rack 2

Asante Hub & Cisco Switch One Asante AH2072 per work area. Hubs simply connect computers & devices together. Deal with 1st and 2nd layer of OSI Internetworking model & TCP/IP stack. Have 5 rows of twelve 10Base-T ports. Ethernet over twisted pair. Use Straight-through Ethernet cable Make sure the light lights up when you plug-in an Ethernet cable. Two Cisco Switches 2600 & one Cisco 3500 per work area. Routers 2600 & 3500 may come with different functions. These are basically routers to connect bridges, switches, & routers to make bigger networks. Routers work at the 3rd layer of the OSI Internetworking model & TCP/IP stack & provide routing functions. Deal with IP addresses.

Alcatel Switches Two Alcatel Omni Switch OS6860-24 per work area Stackable PoE (Packer Over Ethernet) Gigabit Ethernet Switch, can have several valuable features. The model here has 24 Ethernet ports with user authentication, deep packet inspection (DPI), & Virtual LAN application. Performs Layer 2 & some Layer 3 functions Use Straight through Ethernet cable. One Alcatel Omni Switch OS6450-10 per work area. Stackable offer several valuable capabilities. The model here has 10 Ethernet ports for classroom, workgroup & small enterprise segments. Performs Layer 2 & some Layer 3 functions. Use Straight through Ethernet cable. Alcatel Omni Switch OS6450-10 used in Metro Ethernet services

Wiring Diagram of Patch Panel to Equipment

Patch Panel Ports at the top of the patch panel are connected to the ports of each computer in each work area. To connect the computers & other devices together. Eth0 port of each computer is connected to the production network in the SSU campus & Internet directly. Eth1 port of each computer is connected to the server at the back. Eth2 & Eth3 ports are used for students to make LANs in the lab. - Eth 1 & 3 ports are currently disconnected to reduce confusion.

Xyplex Terminals & Servers Xyplex MAXserver 1600 is a terminal server to facilitate access. In each rack in front there is a Xyplex terminal in the patch panel connected to the console of hubs, switches, & routers in that work area. Xyplex terminals in work areas 1, 2, & 3 are served by the Xyplex MAXserver in the corresponding patch panel in the back of the room. work areas 4, 5, & 6 are served by the Xyplex MAXserver in the corresponding patch panel in the back of the room. Xyplex MAXserver 1600 at the back The Xyplex terminal ports 4, 5, & 6 are connected to the 2600 & 3500 routers in each work area. 7, 8, & 9 are connected to Alcatel switches. The Xyplex Maxserver 1600 is a terminal server. It allows access to the console ports of various network devices from remote computers. In each work area there is one terminal server. Each of the two shared racks also has a terminal server. Ports of the terminal server, starting with port 3, are connected to the console ports of the other equipment in the work area. The terminal server is also connected to the private network in the lab. All the computers are also connected to the private network. From any computer it is possible to connect to the console port of any device in the lab. To do so you use telnet, specifying the IP address of the terminal server & the TCP port number associated with the device you are interested in. The TCP port number associated with port p on the terminal server is 2000 + 100 * p. For example, if the device you wish to reach is connected to port 5 of the terminal server, & the terminal server's IP address is 192.168.200.11, then you would issue the following command:      [Linux prompt] # telnet 192.168.200.11 2500 http://www.cs.sonoma.edu/itl/manual/management.html#xyplex1600

Ethernet over Twisted Pair Early Ethernet cabling were originally based on various grades of coaxial cable that were Costly, difficult to work with, .. In 1984 StarLAN/AT&T showed simple CAT3 cable using Unshielded Twisted Pair (UTP) similar to telephony cable can be used. This led to the development of 10BASE-T & its successors 10/100BASE-T & 1000BASE-T, supporting speeds of 10, 100 Mbit/s & 1 & 10 GbE All support full-duplex communication BASE = baseband, T = twisted pair Based on IEEE 802.3 standards Ethernet UTP Cable with RJ45/8P8C plug The twist provides noise immunity. The more twists, the more the immunity. These standards use RJ-45 / 8P8C connectors Cables were improved from CAT3 to CAT7 1 & 10 Gbps have four pairs of wires 10BASE-T & 100BASE-TX only require two of the pairs Most common - 10/100 & 1000 BASE-T CAT6 10BASE-T transmitter sends two differential voltages, +2.5 V or −2.5 V. 100BASE-TX (Fast Ethernet) transmitter sends three differential voltages, +1 V, 0 V, or −1 V 250 MHz (500 MHz for the newer Cat 6a standard) & can be used up to a maximum length of 100 meter unshielded twisted pairs (UTP) of copper wire terminated by RJ45 connectors RJ-11 (Registered Jack) used for telephony RJ-45 (Registered Jack) used in computer networking

Ethernet Cables - RJ45/Colors & Crossover EIA = Electronic Industries Alliance, TIA = Telecommunications Industry Association

Ethernet Cables (RJ45)

Ethernet Cable CAT 5 & CAT6   CAT5e CAT6 Speed 1 Gbps 10 Gbps over 33-55 meters (110-165 feet) of cable Cost Varies by length & manufacturer, generally $0.20 - $0.30 per foot. Varies by length & manufacturer, with $0.40 - $0.60 per foot as an average; generally about 20% higher than Cat5e. Frequency Up to 100MHz Up to 250 MHz Performance Less crosstalk/interference than CAT5. Potentially more interference than CAT6. SNR (Signal-to-Noise Ratio) higher Maximum Cable Length 100 meters 100 meters for slower network speeds (up to 1,000 Mbps) & higher network speeds over short distances. For Gigabit Ethernet, 55 meters max, with 33 meters in high crosstalk conditions. Gauges in conductors 24-26 AWG (American Wire Gage) wire 22-24 AWG wire CAT6 is generally a better choice & worth the small premium in price. CAT5e & CAT6 cables are both backwards compatible. http://www.diffen.com/difference/Cat5e_vs_Cat6
