Chapter 3: Installing the Switch

Fast Ethernet and Gigabit Considerations

If you will be using the Switch for Fast Ethernet (100Mbps) or Gigabit (1000Mbps) applications, you must observe this guideline:

The maximum UTP cabling length using Category 5 cable is 328 feet (100m).

Full-Duplex Considerations

As previously mentioned, the Switch provides full-duplex support for its RJ-45 ports. Full-duplex operation allows data to be sent and received simultaneously, doubling a port’s potential data throughput.

If you will be using the Switch in full-duplex mode, the maximum UTP cable length using Category 5e (or better) cable is 328 feet (100 m).

Positioning the Switch

Before you choose a location for the Switch, observe the following guidelines:

• Keep cabling away from sources of electrical noise, power lines, and fluorescent lighting fixtures.

• Position the Switch away from water and moisture sources.

• To ensure adequate air flow around the Switch, be sure to provide a

minimum of one inch (25 mm) clearance.

• Do not stack free-standing Switches more than four units high.

Instant EtherFast®Series

Pre-Installation Considerations

The Switch is equipped with four 10/100/1000 RJ-45 ports, shown in Figure 2-

2. These RJ-45 ports support network speeds of 10/100 Mbps half-duplex and 20/200 Mbps full duplex Ethernet and Fast Ethernet speeds as well as up to 2000 Mbps Gigabit speed. Auto-sensing technology enables each port to automatically detect the speed of the device connected to it, and adjust its speed and duplex accordingly.

T o connect a de vice to a port, you will need to use a network cable. If you are using 100BaseTX devices you will need to use UTP Category 5 (or better) cable. Gigabit devices require UTP Category 5e cable (or better).

The Switch is equipped with four Gigabit-module ports. These ports allow you to add four high-speed ports, transmitting at speeds of up to 1000Mbps (Gigabit Ethernet).

The Switch is equipped with a RS-232 serial port (located on the rear of the Switch, as shown in Figure 2-3) that allows you to connect to a computer (for configuration pur poses) using the provided serial cable.

If it is not, consult your Windows documentation for instructions on installing HyperTerminal.

1. Click the Start button. Select Accessories and then Communications.

Hyperterminal should be one of the options listed in this menu. Select HyperTerminal, as shown in Figure 4-1.

The Switch can be used as a free-standing unit, or installed in any standard 19inch rack.

Use the following instructions to rack-mount the Switch:

Before you begin, disconnect all cables from the Switch.

1. Place the Switch right side up, with the front panel facing you.

2. Position a mounting bracket over the screw holes on one side of the Switch.

3. Secure the mounting bracket by inserting three screws into the screw holes. Use a screwdriver to tighten the screws, ensuring that they are fastened fir mly in place.

4. Repeat steps 2 and 3 to install the other mounting bracket on the opposite side of the Switch.

5. Insert the Switch into the 19-inch rack and secure it with suitable screws (not provided). Ensure that the ventilation holes are not obstructed.

The rack-mount installation is complete. You can now re-connect the cables to the Switch.

To power on the Switch, simply connect the AC power cord to the back of the Switch, and then plug the power cord into an electrical outlet. The Switch will boot up within approximately 30 seconds.

Any of the Switch’s ports can act as an uplink port, allowing you to uplink to other switches or hubs using a standard Ethernet connection. UTP Category 5e (or better) cable is recommended when using the Gigabit ports.

To uplink the switch, connect one end of a network cable into the Switch, and then connect the other end of the cable into the desired network device’s uplink port.

1000T for 1000Base-T.

•Priority - Def ines the priority for the use of a port in the STA algorithm.

If the path cost for all ports on a switch are the same, the port with the highest priority (that is, lowest value) will be configured as an active link in the Spanning Tree. When more than one port is assigned the highest priority, the port with the lowest numeric identifier will be enabled. The range is 0-255.

•Cost - This parameter is used by the STA algorithm to determine the best

path between devices. Therefore, lower values should be assigned to ports attached to faster media, and higher values assigned to ports with slower media. (This takes precedence over port priority.)

GARP

Group Address Registration Protocol is used by GVRP and GMRP to register or deregister client attributes for client services within a bridged LAN.

•Join Time - The interval (centiseconds) between transmitting

requests/queries to participate in a group.

•Leave Time - The interval (centiseconds) a port waits before leaving a

group. This time should be set to more than twice the Join Time. This ensures that after a Leave or Leave All message has been issued, the applicants can re-join before the port actually leaves the group.

•Leave All Time - The interval (centiseconds) between sending out a

Leave All quer y message for group participants and the port leaving the group. This interval should be considerably larger than the Leave Time to minimize the amount of traffic generated by nodes rejoining the group.

Jumbo Packet Configuration

The Jumbo Packet Configuration screen, shown in Figure 6-66, allows you to utilize jumbo packets. The IEEE 802.3 standard specifies the maximum size of Ethernet frames at 1,518 bytes. A jumbo packet is simply one having up to 65,535 bytes. In a case where a server has to receiv e a massive amount of data, the required overhead of processing the individual frames could have negative effects on the server's CPU, and ultimately on overall server performance.

• Load Default Size - If enabled , the Switch will use the default size for jumbo

packets, which is 1536 bytes.

• Jumbo Packet Length - With Default Size disabled, you can set the jumbo

packet length between 1536 and 9216 bytes.

Category 5e - The additional cabling performance parameters of return loss and far-end crosstalk (FEXT) specified for 1000Base-T and not specified for 10Base-T and 100Base-TX are related to differences in the signaling implementation. 10Base-T and 100Base-TX signaling is unidirectional—signals are transmitted in one direction on a single wire pair. In contrast, Gigabit Ethernet is bidirectional—signals are transmitted simultaneously in both directions on the same wire pair; that is, both the transmit and receive pair occupy the same wire pair.

Data Packet - One frame in a packet-switched message. Most data communications is based on dividing the transmitted message into packets. F or e xample, an Ethernet packet can be from 64 to 1518 bytes in length.

DHCP (Dynamic Host Configuration Protocol) - A protocol that lets network administrators manage centrally and automate the assignment of Internet Protocol (IP) addresses in an organization’s network. Using the Internet’s set of protocol (TCP/IP), each machine that can connect to the Internet needs a unique IP address. When an organization sets up its computer users with a connection to the Internet, an IP address must be assigned to each machine. Without DHCP, the IP address must be entered manually at each computer, and, if computers move to another location in another part of the network, a new IP address must be entered. DHCP lets a network administrator supervise and distribute IP addresses from a central point and automatically sends a new IP address when a computer is plugged into a different place in the network. DHCP uses the concept of a “lease” or amount of time that a given IP address will be valid for a computer. The lease time can vary depending on how long a user is likely to require the Internet connection at a particular location. It’s especially useful in education and other environments where users change frequently. Using very short leases, DHCP can dynamically reconfigure networks in which there are more computers than there are available IP addresses.

DHCP supports static addresses for computers containing Web servers that need a permanent IP address.

DVMRP (Distance-Vector Multicast Routing Protocol) - Used for routing multicast messages through the Internet.

Ethernet - IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium. Has a transfer rate of 10Mbps. Forms the underlying transport vehicle used by several upper-level protocols, including TCP/IP and XNS.

Fast Ethernet - A 100 Mbps technology based on the 10Base-T Ethernet CSMA/CD network access method.

Appendix D: Glossary

10BaseT - An Ethernet standard that uses twisted wire pairs.

100BaseTX - IEEE physical layer specification for 100Mbps over two pairs of

Category 5 UTP wire.

1000BASE-T - Provides half-duplex (CSMA/CD) and full-duplex 1000Mbps Ethernet service over Category 5e links as defined by ANSI/TIA/EIA-568-A. Topology rules for 1000Base-T are the same as those used for 100Base-TX. Category 5e link lengths are limited to 100 meters by the ANSI/TIA/EIA-568A cabling standard. Only one CSMA/CD repeater will be allowed in a collision domain.

ARP (Address Resolution Protocol) - A TCP/IP protocol used to f igure out a host’s Ethernet address from its Internet address.

Auto-negotiate - To automatically determine the correct settings. The term is often used with communications and networking. For example, Ethernet 10/100 cards, hubs, and switches can determine the highest speed of the node they are connected to and adjust their transmission rate accordingly.

Backbone - The part of a network that connects most of the systems and networks together and handles the most data.

Bandwidth - The transmission capacity of a given facility, in terms of how much data the facility can transmit in a fixed amount of time; expressed in bits per second (bps).

BOOTP (BOOTstrap Protocol) - A TCP/IP protocol that lets a device connected to the network be automatically configured and booted up. An IP address is automatically assigned for a specific length of time.

Category 5 - ANSI/EIA (American National Standards Institute/Electronic Industries Association) Standard 568 is one of several standards that specify “categories” (the singular is commonly referred to as “CAT”) of twisted pair cabling systems (wires, junctions, and connectors) in terms of the data rates that they can sustain. CAT 5 cable has a maximum throughput of 100Mbps and is usually utilized for 100BaseTX networks.

The IEEE fosters the development of standards that often become national and international standards. The organization publishes a number of journals, has many local chapters, and has several lar ge societies in special areas, such as the IEEE Computer Society.

IGMP (Inter net Group Management Protocol) - A multicast host registration protocol that allows any host to inform its local router that it wants to receive transmissions addressed to a specific multicast g roup.

LAN - A local area network (LAN) is a group of computers and associated devices that share a common communications line and typically share the resources of a single processor or server within a small geographic area (for example, within an office building).

Layer 2 - Data Link layer in the ISO 7-Layer Data Communications Protocol. This is directly related to the hardware interface for network devices and passes traffic based on MAC addresses.

Layer 3 - Network layer in the ISO 7-Layer Data Communications Protocol. This layer handles the routing functions for data moving from one open system to another.

MAC Addr ess - The MAC (Media Access Control) address is your computer’s unique hardware number.

Mbps (MegaBits Per Second) - One million bits per second; unit of measurement for data transmission.

Multicast Routing Protocol - A routing protocol that supports multicast packets (one to many).

Multicasting - Sends data to a group of nodes instead of a single destination.

Network - A system that transmits any combination of voice, video, and/or

data between users.

Port - A pathway into and out of the computer or a network device such as a switch or router. For example, the serial and parallel ports on a personal computer are external sockets for plugging in communications lines, modems, and printers.

Full Duplex - The ability of a device or line to transmit data simultaneously in both directions.

GARP (General Attributes Registration Protocol) - A standard for registering or deregistering client attributes for client services within a bridged LAN.

GMRP (GARP Multicast Registration Protocol) - Allows network devices to register endstations with multicast groups. GMRP requires that any participating network devices or endstations comply with the IEEE 802.1p standard.

GVRP (GARP VLAN Registration Protocol) - Defines a way for switches to exchange VLAN information in order to register VLAN members on ports across the network.

Half Duplex - Data transmission that can occur in two directions over a single line, but only one direction at a time.

Hardware - Hardware is the physical aspect of computers, telecommunications, and other information technology devices. The term arose as a way to distinguish the “box” and the electronic circuitry and components of a computer from the program you put in it to make it do things. The pro gram came to be known as the software.

Hub - The device that serves as the central location for attaching wires from workstations. Can be passive, where there is no amplification of the signals; or active, where the hubs are used like repeaters to provide an extension of the cable that connects to a workstation.

HyperTerminal - A basic communications pro gram that is an accessory for all Windows operating systems, starting with Windows 95. It enables your computer to communicate with other compatible devices, using either a standard RS-232 cable, null modem cable, or modem. It can also be referred to as a VT100 or ANSI terminal application.

IEEE - The Institute of Electrical and Electronics Engineers. The IEEE describes itself as “the world’s largest technical professional society—promoting the development and application of electrotechnology and allied sciences for the benefit of humanity, the advancement of the profession, and the wellbeing of our members.”

UTP - Unshielded twisted pair is the most common kind of copper telephone wiring. Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company. To reduce crosstalk or electromagnetic induction between pairs of wires, two insulated copper wires are twisted around each other. Each signal on twisted pair requires both wires. Since some telephone sets or desktop locations require multiple connections, twisted pair is sometimes installed in two or more pairs, all within a single cable.

VLAN (Virtual LAN) - A logical association that allows users to communicate as if they were physically connected to a single LAN, independent of the actual physical configuration of the network.

Port Trunk - Def ines a network link aggregation and trunking method, which specifies how to create a single high-speed logical link that combines several lower-speed physical links.

RIP (Routing Information Protocol) - A simple routing protocol that is part of the TCP/IP protocol suite. It determines a route based on the smallest hop count between source and destination. RIP is a distance vector protocol that routinely broadcasts routing information to its neighboring routers and is known to waste bandwidth. AppleTalk, DECnet, TCP/IP, NetWare, and VINES all use incompatible versions of RIP.

RJ-45 (Registered Jack-45) - A connector similar to a telephone connector that holds up to eight wires, used for connecting Ethernet devices.

RMON (Remote MONitoring) - RMON provides comprehensive network monitoring capabilities. It eliminates the polling required in standard SNMP, and can set alarms on a variety of traffic conditions, including specif ic error types.

SNMP (Simple Network Management Protocol)- A widely used netw ork monitoring and control protocol. Data is passed from SNMP agents, which are hardware and/or software processes reporting activity in each network device (hub, router, bridge, etc.) to the workstation console used to oversee the network. The agents return information contained in a MIB (Management Information Base), which is a data structure that def ines what is obtainable from the device and what can be controlled (turned off, on, etc.).

Static Routing - Forwarding data in a network via a fixed path. Static routing cannot adjust to changing line conditions as can dynamic routing.

Subnet Mask - The method used for splitting IP networks into a series of subgroups, or subnets. The mask is a binary pattern that is matched up with the IP address to turn part of the host ID address field into a f ield for subnets.

TFTP (Trivial File Transfer Protocol) - A version of the TCP/IP FTP protocol that has no directory or password capability.

Throughput- The amount of data mov ed successfully from one place to another in a given time period.

Unicast Routing Protocol - A routing protocol that does not support multicast.
