The RJ-45 Ports

Installing the Switch

The Switch is equipped with twenty-four 10/100 RJ-45 ports. These RJ-45

ports support network speeds of either 10-100Mbps in half-duplex mode, or

20-200Mbps in full-duplex mode. Auto-sensing technology enables each port

to automatically detect the speed of the device connected to it (10Mbps or

100Mbps), and adjust its speed and duplex accordingly.

Pre-Installation Considerations

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:

To connect a device 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. The two Gigabit ports require UTP Category 5e cable (or better).

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 simultaneous-

ly, doubling a port’s potential data throughput.

The Gigabit Ports

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).

The Switch is equipped with two Gigabit ports. These ports provide links to

high-speed network segments or individual workstations at speeds of up to

1000Mbps (Gigabit Ethernet). The two Gigabit ports require UTP Category 5e

cable (or better).

Positioning the Switch

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

The Console Port

• Keep cabling away from sources of electrical noise, power lines, and fluores-

cent lighting fixtures.

The Switch is equipped with a RS-232 serial port (located on the rear of the

Switch) that allows you to connect to a computer (for configuration purposes)

using the provided serial cable.

• 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.

Rack-Mounting the Switch

Switch Management

The Switch offers an easy-to-use, menu-driven configuration program. This

program can be accessed by a console interface, a Web browser, a telnet con-

nection, or SNMP/RMON. Using this configuration program, you can perform

various switch configuration and management activities, including:

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

inch rack.

Use the following instructions to rack-mount the Switch:

Before you begin, disconnect all cables from the Switch.

• Enable/disable any port

• Set the communication mode for any port

• Configure SNMP parameters

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.

• Add ports to network VLANs

• Create and manage VLAN Configurations

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

firmly in place.

Local Console Management

You can manage the Switch locally using HyperTerminal; simply connect the

Switch to a PC or workstation through the serial port.

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

side of the Switch.

The serial port settings need to be configured before connecting to the Switch.

In order to change the settings of your port, run the HyperTerminal program.

This program comes packaged with Windows, but it may not be installed on

your computer. It should be located as is shown below (varies according to

operating system). If it is not, consult your Windows documentation for

instructions on installing HyperTerminal.

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.

Powering on the Switch

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

Hyperterminal should be one of the options listed in this menu. Select

HyperTerminal.

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.

Uplinking the Switch

Any of the 26 ports on the Switch 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.

Port Trunking Configuration

Mirror Port Configuration

Ports can be combined into an aggregate link to increase the bandwidth of

a network connection or ensure fault recovery. You can configure trunks

between any two switches. The RJ-45 ports on this Switch can be grouped

into a trunk consisting of two, four, or eight ports, creating an aggregate

bandwidth up to 400, 800, or 1600Mbps when operating at full duplex.

The Mirror Port Configuration screen allows you to mirror traffic from any

source port to a target port for real-time analysis. You can then attach a logic

analyzer or RMON probe to the target port and study the traffic crossing the

source port in a completely unobtrusive manner. When mirroring port traf-

fic, the target port must be included in the same VLAN as the source port.

bridge priority, hello time, forward delay, maximum message age), GMRP,

GVRP, traffic class priority threshold, and address aging time.

•Bridge Priority - Bridge priority is used in selecting the root device,

root port, and designated port. The device with the highest priority

becomes the STA root device. However, if all devices have the same pri-

ority, the device with the lowest MAC address will then become the root

device. Enter a value from 0-65535. The lower the numeric value, the

higher the priority.

“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 3 cable has a maximum throughput of 16Mbps and

is usually utilized for 10BaseT networks.

Glossary

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

CAT 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.

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-568-

A cabling standard. Only one CSMA/CD repeater will be allowed in a collision

domain.

CAT 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 bi-direc-

tional—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.

Adapter - Printed circuit board that plugs into a PC to add capabilities or con-

nectivity to a PC. In a networked environment, a network interface card (NIC)

is the typical adapter that allows the PC or server to connect to the intranet

and/or Internet.

Data Packet - One frame in a packet-switched message. Most data communi-

cations is based on dividing the transmitted message into packets. For example,

an Ethernet packet can be from 64 to 1518 bytes in length.

ARP (Address Resolution Protocol) - A TCP/IP protocol used to figure out a

host’s Ethernet address from its Internet address.

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 con-

nection 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 dis-

tribute 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 fre-

quently. Using very short leases, DHCP can dynamically reconfigure networks

in which there are more computers than there are available IP addresses.

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 net-

works 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 connect-

ed to the network be automatically configured and booted up. An IP address is

automatically assigned for a specific length of time.

DHCP supports static addresses for computers containing Web servers that

need a permanent IP address.

CAT 3 - ANSI/EIA (American National Standards Institute/Electronic

Industries Association) Standard 568 is one of several standards that specify

DVMRP (Distance-Vector Multicast Routing Protocol) - Used for routing multi-

cast messages through the Internet.

HyperTerminal - A basic communications program that is an accessory for all

Windows operating systems, starting with Windows 95. It enables your com-

puter 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.

Dynamic Routing - The ability for a router to forward data via a different route

based on the current conditions of the communications circuits. For example, it

can adjust for overloaded traffic or failing lines and is much more flexible than

static routing, which uses a fixed forwarding path.

IEEE - The Institute of Electrical and Electronics Engineers. The IEEE

describes itself as “the world’s largest technical professional society—promot-

ing the development and application of electrotechnology and allied sciences

for the benefit of humanity, the advancement of the profession, and the well-

being of our members.”

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 pro-

tocols, including TCP/IP and XNS.

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 large societies in special areas, such as the

IEEE Computer Society.

Fast Ethernet - A 100 Mbps technology based on the 10Base-T Ethernet

CSMA/CD network access method.

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

both directions.

IGMP (Internet 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 group.

GARP (General Attributes Registration Protocol) - A standard for registering or

deregistering client attributes for client services within a bridged LAN.

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).

GMRP (GARP Multicast Registration Protocol) - Allows network devices to

ing 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.

Latency - The time delay between when the first bit of a packet is received and

the last bit is forwarded.

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 pass-

es traffic based on MAC addresses.

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 pro-

gram you put in it to make it do things. The program came to be known as the soft-

ware.

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 Address - The MAC (Media Access Control) address is your computer’s

unique hardware number.

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.

Mbps (MegaBits Per Second) - One million bits per second; unit of measure-

ment for data transmission.

Multicast Routing Protocol - A routing protocol that supports multicast pack-

ets (one to many).

(hub, router, bridge, etc.) to the workstation console used to oversee the net-

work. The agents return information contained in a MIB (Management

Information Base), which is a data structure that defines what is obtainable

from the device and what can be controlled (turned off, on, etc.).

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.

STP (Spanning Tree Protocol) - A technology that checks your network for any

loops. A loop can often occur in complicated or back-up linked network sys-

tems. Spanning-tree detects and directs data along the shortest path, maximiz-

ing the performance and efficiency of the network.

NIC (Network Interface Card) - A board installed in a computer system, usu-

ally a PC, to provide network communication capabilities to and from that com-

puter system. Also called an adapter.

Static Routing - Forwarding data in a network via a fixed path. Static routing

cannot adjust to changing line conditions as can dynamic routing.

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 com-

puter are external sockets for plugging in communications lines, modems, and

printers.

Subnet Mask - The method used for splitting IP networks into a series of sub-

groups, 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 field for subnets.

Port Trunk - Defines 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.

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 moved successfully from one place to anoth-

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 routine-

ly 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.

er in a given time period.

TX Rate - Transmission Rate.

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

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 electro-

magnetic 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.

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 specific error

types.

SNMP (Simple Network Management Protocol) - A widely used network mon-

itoring and control protocol. Data is passed from SNMP agents, which are

hardware and/or software processes reporting activity in each network device

VLAN (Virtual LAN) - A logical association that allows users to communicate

as if they were physically connected to a single LAN, independent of the actu-

al physical configuration of the network.
