Chapter 1: Introduction

Overview

The ES3510 is a Fast Ethernet switch with eight 10BASE-T/100BASE-TX ports and
two 1000BASE-T ports that operate in combination with two Small Form Factor

Pluggable (SFP) transceiver slots

*

(see Figure 1-1, Ports 9-10). The switch also
includes an SNMP-based management agent, which provides both in-band and
out-of-band access for managing the switch.

The ES3510 provides a broad range of powerful features for Layer 2 switching,
delivering reliability and consistent performance for your network traffic. It brings
order to poorly performing networks by segregating them into separate broadcast
domains with IEEE 802.1Q compliant VLANs, and empowers multimedia
applications with multicast switching and CoS services.

Switch Architecture

The switch employs a wire-speed, non-blocking switching fabric. This permits
simultaneous wire-speed transport of multiple packets at low latency on all ports.
The switch also features full-duplex capability on all ports, which effectively doubles
the bandwidth of each connection.

This switch uses store-and-forward switching to ensure maximum data integrity.
With store-and-forward switching, the entire packet must be received into a buffer
and checked for validity before being forwarded. This prevents errors from being
propagated throughout the network.

Network Management Options

With a comprehensive array of LEDs, the switch provides “at a glance” monitoring of
network and port status. The switch can be managed over the network with a web
browser or Telnet application, or via a direct connection to the console port. The
switch includes a built-in network management agent that allows it to be managed
in-band using SNMP or RMON (Groups 1, 2, 3, 9) protocols. It also has an RS-232
serial port (DB-9 connector) on the rear panel for out-of-band management. A PC
may be connected to this port

for configuration and monitoring out-of-band via a

null-modem serial cable. (See Appendix B for wiring options.)

For a detailed description of the management features, refer to the Management
Guide.

Description of Hardware

10BASE-T/100BASE-TX Ports

The switch contains eight 10BASE-T/100BASE-TX RJ-45 ports. All ports support
automatic MDI/MDI-X operation, so you can use straight-through cables for all
network connections to PCs or servers, or to other switches or hubs. (See
“10BASE-T/100BASE-TX Pin Assignments” on page B-1.)

Each of these ports support auto-negotiation, so the optimum transmission mode
(half or full duplex), and data rate (10 or 100 Mbps) can be selected automatically. If
a device connected to one of these ports does not support auto-negotiation, the
communication mode of that port can be configured manually.

Each port also supports IEEE 802.3x auto-negotiation of flow control, so the switch
can automatically prevent port buffers from becoming saturated.

1000BASE-T/SFP Ports

These are combination Gigabit RJ-45 ports with shared Small Form Factor
Pluggable (SFP) transceiver slots. If an SFP transceiver (purchased separately) is
installed in a slot and has a valid link on the port, the associated RJ-45 port is
disabled.

The 1000BASE-T RJ-45 ports support automatic MDI/MDI-X operation, so you can
use straight-through cables for all network connections to PCs or servers, or to other
switches or hubs. (See “1000BASE-T Pin Assignments” on page B-3.)

Port and System Status LEDs

The switch includes a display panel for key system and port indications that simplify
installation and network troubleshooting. The LEDs, which are located on the front
panel for easy viewing, are shown below and described in the following tables.

Chapter 2: Network Planning

Introduction to Switching

A network switch allows simultaneous transmission of multiple packets via
non-crossbar switching. This means that it can partition a network more efficiently
than bridges or routers. The switch has, therefore, been recognized as one of the
most important building blocks for today’s networking technology.

When performance bottlenecks are caused by congestion at the network access
point (such as the network card for a high-volume file server), the device
experiencing congestion (server, power user, or hub) can be attached directly to a
switched port. And, by using full-duplex mode, the bandwidth of the dedicated
segment can be doubled to maximize throughput.

When networks are based on repeater (hub) technology, the distance between end
stations is limited by a maximum hop count. However, a switch turns the hop count
back to zero. So subdividing the network into smaller and more manageable
segments, and linking them to the larger network by means of a switch, removes this
limitation.

A switch can be easily configured in any Ethernet, Fast Ethernet, or Gigabit Ethernet
network to significantly boost bandwidth while using conventional cabling and
network cards.

Application Examples

The switch is not only designed to segment your network, but also to provide a wide
range of options in setting up network connections. Some typical applications are
described below.

Collapsed Backbone

The switch is an excellent choice for mixed Ethernet, Fast Ethernet, and Gigabit
Ethernet installations where significant growth is expected in the near future. You
can easily build on this basic configuration, adding direct full-duplex connections to
workstations or servers. When the time comes for further expansion, just connect to
another hub or switch using one of the Fast Ethernet ports built into the front panel
or a Gigabit Ethernet port on a plug-in SFP transceiver.

In the figure below, the switch is operating as a collapsed backbone for a small LAN.
It is providing dedicated 10 Mbps full-duplex connections to workstations, 100 Mbps
full-duplex connections to power users, and 1 Gbps full-duplex connections to
servers.

Network Aggregation Plan

With 10 parallel bridging ports (i.e., 10 distinct collision domains), the switch can
collapse a complex network down into a single efficient bridged node, increasing
overall bandwidth and throughput.

In the figure below, the 10BASE-T/100BASE-TX ports on the switch are providing
100 Mbps connectivity for up to eight segments. In addition, the switch is also
connecting servers at 1000 Mbps.

Remote Connections with Fiber Cable

Fiber optic technology allows for longer cabling than any other media type. A
1000BASE-SX (MMF) link can connect to a site up to 550 meters away, a
1000BASE-LX (SMF) link up to 5 km, and a 1000BASE-LH link up to 70 km. This
allows the switch to serve as a collapsed backbone, providing direct connectivity for
a widespread LAN.

The figure below illustrates the switch connecting multiple segments with fiber cable.

Making VLAN Connections

This switch supports VLANs that can be used to organize any group of network
nodes into separate broadcast domains. VLANs confine broadcast traffic to the
originating group, and can eliminate broadcast storms in large networks. This
provides a more secure and cleaner network environment.

VLANs can be based on untagged port groups, or traffic can be explicitly tagged to
identify the VLAN group to which it belongs. Untagged VLANs can be used for small
networks attached to a single switch. However, tagged VLANs should be used for
larger networks, and all the VLANs assigned to the inter-switch links.

Figure 2-4 Making VLAN Connections

Note: When connecting to a switch that does not support IEEE 802.1Q VLAN tags, use

untagged ports.

Application Notes

1. Full-duplex operation only applies to point-to-point access (such as when a
switch is attached to a workstation, server or another switch). When the switch
is connected to a hub, both devices must operate in half-duplex mode.

2. Avoid using flow control on a port connected to a hub unless it is actually
required to solve a problem. Otherwise back pressure jamming signals may
degrade overall performance for the segment attached to the hub.

3. As a general rule the length of fiber optic cable for a single switched link should
not exceed:

• 1000BASE-SX: 550 m (1805 ft) for multimode fiber.

• 1000BASE-LX: 5 km (3.1 miles) for single-mode fiber.

• 1000BASE-LH: 70 km (43.5 miles) for single-mode fiber.

However, power budget constraints must also be considered when calculating
the maximum cable length for your specific environment.

Chapter 3: Installing the Switch

Selecting a Site

Switch units can be mounted in a standard 19-inch equipment rack or on a flat
surface. Be sure to follow the guidelines below when choosing a location.

• The site should:

- be at the center of all the devices you want to link and near a power outlet.

- be able to maintain its temperature within 0 to 50 °C (32 to 122 °F) and its
humidity within 10% to 90%, non-condensing

- provide adequate space (approximately two inches) on all sides for proper air
flow

- be accessible for installing, cabling and maintaining the devices

- allow the status LEDs to be clearly visible

• Make sure twisted-pair cable is always routed away from power lines, fluorescent
lighting fixtures and other sources of electrical interference, such as radios and
transmitters.

• Make sure that the unit is connected to a separate grounded power outlet that
provides 100 to 240 VAC, 50 to 60 Hz, is within 2 m (6.6 feet) of each device and
is powered from an independent circuit breaker. As with any equipment, using a
filter or surge suppressor is recommended.

Ethernet Cabling

To ensure proper operation when installing the switch into a network, make sure that
the current cables are suitable for 10BASE-T, 100BASE-TX or 1000BASE-T
operation. Check the following criteria against the current installation of your
network:

• Cable type: Unshielded twisted pair (UTP) or shielded twisted pair (STP) cables
with RJ-45 connectors; Category 3 or better for 10BASE-T, Category 5 or better
for 100BASE-TX, and Category 5, 5e or 6 for 1000BASE-T.

• Protection from radio frequency interference emissions

• Electrical surge suppression

• Separation of electrical wires (switch related or other) and electromagnetic fields
from data based network wiring

• Safe connections with no damaged cables, connectors or shields

Mounting

The switch can be mounted in a standard 19-inch equipment rack or on a desktop or
shelf. Mounting instructions for each type of site follow.

Rack Mounting

Before rack mounting the switch, pay particular attention to the following factors:

• Temperature: Since the temperature within a rack assembly may be higher than
the ambient room temperature, check that the rack-environment temperature is
within the specified operating temperature range. (See page C-1.)

• Mechanical Loading: Do not place any equipment on top of a rack-mounted unit.

• Circuit Overloading: Be sure that the supply circuit to the rack assembly is not
overloaded.

• Grounding: Rack-mounted equipment should be properly grounded. Particular
attention should be given to supply connections other than direct connections to
the mains.

To rack-mount devices:

1. Attach the brackets to the device using the screws provided in the Bracket

Mounting Kit.

The SFP slots support the following optional SFP transceivers:

• 1000BASE-SX

• 1000BASE-LX

• 1000BASE-LH

To install an SFP transceiver, do the following:

1. Consider network and cabling requirements to select an appropriate SFP
transceiver type.

2. Insert the transceiver with the optical connector facing outward and the slot
connector facing down. Note that SFP transceivers are keyed so they can only
be installed in one orientation.

3. Slide the SFP transceiver into the slot until it clicks into place.

Note: SFP transceivers are hot-swappable. The switch does not need to be powered off

before installing or removing a transceiver. However, always first disconnect the
network cable before removing a transceiver.

Note: SFP transceivers are not provided in the switch package.

Connecting to a Power Source

To connect a switch to a power source:

1. Insert the power cable plug directly into the AC socket located at the back of the
switch.

Figure 3-6 Power Socket

2. Plug the other end of the cable into a grounded, three-pin, AC power source.

Note: For International use, you may need to change the AC line cord. You must

use a line cord set that has been approved for the receptacle type in your
country.

3. Check the front-panel LEDs as the device is powered on to be sure the Power
LED is lit. If not, check that the power cable is correctly plugged in.

Chapter 4: Making Network Connections

Connecting Network Devices

The switch is designed to be connected to 10 or 100 Mbps network cards in PCs and
servers, as well as to other switches and hubs. It may also be connected to remote
devices using optional 1000BASE-SX, 1000BASE-LX, or 1000BASE-LH SFP
transceivers.

Twisted-Pair Devices

Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors
at both ends. Use Category 5, 5e or 6 cable for 1000BASE-T connections, Category
5 or better for 100BASE-TX connections, and Category 3 or better for 10BASE-T
connections.

Cabling Guidelines

The RJ-45 ports on the switch support automatic MDI/MDI-X pinout configuration, so
you can use standard straight-through twisted-pair cables to connect to any other
network device (PCs, servers, switches, routers, or hubs).

See Appendix B for further information on cabling.

Caution: Do not plug a phone jack connector into an RJ-45 port. This will damage the

switch. Use only twisted-pair cables with RJ-45 connectors that conform to
FCC standards.

Making Network Connections

Connecting to PCs, Servers, Hubs and Switches

1. Attach one end of a twisted-pair cable segment to the device’s RJ-45
connector.

Figure 4-1 Making Twisted-Pair Connections

2. If the device is a network card and the switch is in the wiring closet, attach the
other end of the cable segment to a modular wall outlet that is connected to the
wiring closet. (See the section “Network Wiring Connections.”) Otherwise,
attach the other end to an available port on the switch.

Make sure each twisted pair cable does not exceed 100 meters (328 ft) in
length.

Note: Avoid using flow control on a port connected to a hub unless it is actually required

to solve a problem. Otherwise back pressure jamming signals may degrade
overall performance for the segment attached to the hub.

3. As each connection is made, the Link LED (on the switch) corresponding to
each port will light green (1000 Mbps) or amber (10/100 Mbps) to indicate that
the connection is valid.

Network Wiring Connections

Today, the punch-down block is an integral part of many of the newer equipment
racks. It is actually part of the patch panel. Instructions for making connections in the
wiring closet with this type of equipment follows.

1. Attach one end of a patch cable to an available port on the switch, and the other
end to the patch panel.

2. If not already in place, attach one end of a cable segment to the back of the
patch panel where the punch-down block is located, and the other end to a
modular wall outlet.

Fiber Optic SFP Devices

An optional Gigabit SFP transceiver (1000BASE-SX, 1000BASE-LX or
1000BASE-LH) can be used for a backbone connection between switches, or for
connecting to a high-speed server.

Each single-mode fiber port requires 9/125 micron single-mode fiber optic cable with
an LC connector at both ends. Each multimode fiber optic port requires 50/125 or

62.5/125 micron multimode fiber optic cabling with an LC connector at both ends.

Warning: This switch uses lasers to transmit signals over fiber optic cable. The lasers are

compliant with the requirements of a Class 1 Laser Product and are inherently
eye safe in normal operation. However, you should never look directly at a
transmit port when it is powered on.

Warning: When selecting a fiber SFP device, considering safety, please make sure that it

can function at a temperature that is not less than the recommended maximum
operational temperature of the product. You must also use an approved Laser
Class 1 SFP transceiver.

Hinweis: Bei der Wahl eines Glasfasertransceivers muß für die Beurteilung der

Gesamtsicherheit beachtet werden, das die maximale Umgebungstemperatur
des Transceivers für den Betrieb nicht niedriger ist als die für dieses Produkts.
Der Glasfasertransceiver muß auch ein überprüftes Gerät der Laser Klasse 1
sein.

1. Remove and keep the LC port’s rubber plug. When not connected to a fiber
cable, the rubber plug should be replaced to protect the optics.

2. Check that the fiber terminators are clean. You can clean the cable plugs by
wiping them gently with a clean tissue or cotton ball moistened with a little
ethanol. Dirty fiber terminators on fiber optic cables will impair the quality of the
light transmitted through the cable and lead to degraded performance on the
port.

3. Connect one end of the cable to the LC port on the switch and the other end to
the LC port on the other device. Since LC connectors are keyed, the cable can
be attached in only one orientation.

Connectivity Rules

4-5

Figure 4-3 Making Fiber Port Connections

4. As a connection is made, check the Link LED on the switch corresponding to
the port to be sure that the connection is valid.

The 1000BASE-SX, 1000BASE-LX, 1000BASE-LH fiber optic ports operate at
1 Gbps, full duplex, with auto-negotiation of flow control. The maximum length for
fiber optic cable operating at Gigabit speed will depend on the fiber type as listed
under “1000 Mbps Gigabit Ethernet Collision Domain” on page 4-6.

Connectivity Rules

When adding hubs (repeaters) to your network, please follow the connectivity rules
listed in the manuals for these products. However, note that because switches break
up the path for connected devices into separate collision domains, you should not
include the switch or connected cabling in your calculations for cascade length
involving other devices.

1000BASE-T Cable Requirements

All Category 5 UTP cables that are used for 100BASE-TX connections should also
work for 1000BASE-T, providing that all four wire pairs are connected. However, it is
recommended that for all critical connections, or any new cable installations,
Category 5e (enhanced Category 5) or Category 6 cable should be used. The
Category 5e and 6 specifications include test parameters that are only
recommendations for Category 5. Therefore, the first step in preparing existing
Category 5 cabling for running 1000BASE-T is a simple test of the cable installation
to be sure that it complies with the IEEE 802.3-2005 standards.

Cable Labeling and Connection Records

When planning a network installation, it is essential to label the opposing ends of
cables and to record where each cable is connected. Doing so will enable you to
easily locate inter-connected devices, isolate faults and change your topology
without need for unnecessary time consumption.

To best manage the physical implementations of your network, follow these
guidelines:

• Clearly label the opposing ends of each cable.

• Using your building’s floor plans, draw a map of the location of all

network-connected equipment. For each piece of equipment, identify the devices
to which it is connected.

• Note the length of each cable and the maximum cable length supported by the

switch ports.

• For ease of understanding, use a location-based key when assigning prefixes to

your cable labeling.

• Use sequential numbers for cables that originate from the same equipment.

• Differentiate between racks by naming accordingly.

• Label each separate piece of equipment.

• Display a copy of your equipment map, including keys to all abbreviations at each

equipment rack.

Diagnosing Switch Indicators

Power and Cooling Problems

If the power indicator does not turn on when the power cord is plugged in, you may
have a problem with the power outlet, power cord, or internal power supply.
However, if the unit powers off after running for a while, check for loose power
connections, power losses or surges at the power outlet. If you still cannot isolate
the problem, the internal power supply may be defective.

Installation

Verify that all system components have been properly installed. If one or more
components appear to be malfunctioning (such as the power cord or network
cabling), test them in an alternate environment where you are sure that all the other
components are functioning properly.

Table A-1 Troubleshooting Chart

Symptom Action

Power LED is Off • Check connections between the switch, the power cord and the wall outlet.

• Contact your dealer for assistance.

Diag LED is Amber • Power cycle the switch to try and clear the condition.

• If the condition does not clear, contact your dealer for assistance.

Link LED is Off • Verify that the switch and attached device are powered on.

• Be sure the cable is plugged into both the switch and corresponding device.

• If the switch is installed in a rack, check the connections to the punch-down
block and patch panel.

• Verify that the proper cable type is used and its length does not exceed
specified limits.

• Check the adapter on the attached device and cable connections for
possible defects. Replace the defective adapter or cable if necessary.

Troubleshooting

In-Band Access

You can access the management agent in the switch from anywhere within the
attached network using Telnet, a web browser, or other network management
software tools. However, you must first configure the switch with a valid IP address,
subnet mask, and default gateway. If you have trouble establishing a link to the
management agent, check to see if you have a valid network connection. Then
verify that you entered the correct IP address. Also, be sure the port through which
you are connecting to the switch has not been disabled. If it has not been disabled,
then check the network cabling that runs between your remote location and the
switch.

Note: The management agent accepts up to four simultaneous Telnet sessions. If the

maximum number of sessions already exists, an additional Telnet connection will
not be able to log into the system.

B-1

Appendix B: Cables

Twisted-Pair Cable and Pin Assignments

For 10/100BASE-TX connections, the twisted-pair cable must have two pairs of
wires. For 1000BASE-T connections the twisted-pair cable must have four pairs of
wires. Each wire pair is identified by two different colors. For example, one wire
might be green and the other, green with white stripes. Also, an RJ-45 connector
must be attached to both ends of the cable.

Caution: DO NOT plug a phone jack connector into any RJ-45 port. Use only

twisted-pair cables with RJ-45 connectors that conform with FCC standards.

Caution: Each wire pair must be attached to the RJ-45 connectors in a specific

orientation.

The figure below illustrates how the pins on the RJ-45 connector are numbered. Be
sure to hold the connectors in the same orientation when attaching the wires to the
pins.

Figure B-1 RJ-45 Connector Pin Numbers

10BASE-T/100BASE-TX Pin Assignments

Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45
connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or
100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure

that the

length of any twisted-pair connection does not exceed 100 meters (328 feet).

The RJ-45 ports on the switch base unit support automatic MDI/MDI-X operation, so
you can use straight-through cables for all network connections to PCs or servers, or
to other switches or hubs. In straight-through cable, pins 1, 2, 3, and 6, at one end of
the cable, are connected straight through to pins 1, 2, 3, and 6 at the other end of
the cable. When using any RJ-45 port on this switch, you can use either
straight-through or crossover cable.

Straight-Through Wiring

If the twisted-pair cable is to join two ports and only one of the ports has an internal
crossover (MDI-X), the two pairs of wires must be straight-through. (When
auto-negotiation is enabled for any RJ-45 port on this switch, you can use either
straight-through or crossover cable to connect to any device type.)

You must connect all four wire pairs as shown in the following diagram to support
Gigabit Ethernet.

Figure B-2 Straight-through Wiring

Crossover Wiring

If the twisted-pair cable is to join two ports and either both ports are labeled with an
“X” (MDI-X) or neither port is labeled with an “X” (MDI), a crossover must be
implemented in the wiring. (When auto-negotiation is enabled for any RJ-45 port on
this switch, you can use either straight-through or crossover cable to connect to any
device type.)

Cable Testing for Existing Category 5 Cable

Installed Category 5 cabling must pass tests for Attenuation, Near-End Crosstalk
(NEXT), and Far-End Crosstalk (FEXT). This cable testing information is specified in
the ANSI/TIA/EIA-TSB-67 standard. Additionally, cables must also pass test
parameters for Return Loss and Equal-Level Far-End Crosstalk (ELFEXT). These
tests are specified in the ANSI/TIA/EIA-TSB-95 Bulletin, “The Additional
Transmission Performance Guidelines for 100 Ohm 4-Pair Category 5 Cabling.”

Note that when testing your cable installation, be sure to include all patch cables
between switches and end devices.

Adjusting Existing Category 5 Cabling to Run 1000BASE-T

If your existing Category 5 installation does not meet one of the test parameters for
1000BASE-T, there are basically three measures that can be applied to try and
correct the problem:

1. Replace any Category 5 patch cables with high-performance Category 5e or
Category 6 cables.

2. Reduce the number of connectors used in the link.

3. Reconnect some of the connectors in the link.

Fiber Standards

The current TIA (Telecommunications Industry Association) 568-A specification on
optical fiber cabling consists of one recognized cable type for horizontal subsystems
and two cable types for backbone subsystems.

Horizontal 62.5/125 micron multimode (two fibers per outlet).
Backbone 62.5/125 micron multimode or single-mode.

TIA 568-B will allow the use of 50/125 micron multimode optical fiber in both the
horizontal and backbone in addition to the types listed above. All optical fiber
components and installation practices must meet applicable building and safety
codes.

twisted-pair cable (using all four wire pairs).

Auto-Negotiation

Signalling method allowing each node to select its optimum operational mode (e.g.,
speed and duplex mode) based on the capabilities of the node to which it is
connected.

Bandwidth

The difference between the highest and lowest frequencies available for network
signals. Also synonymous with wire speed, the actual speed of the data
transmission along the cable.

Glossary

Glossary-2

Collision

A condition in which packets transmitted over the cable interfere

with each other.

Their interference makes both signals unintelligible.

Collision Domain

Single CSMA/CD LAN segment.

CSMA/CD

CSMA/CD (Carrier Sense Multiple Access/Collision Detect) is the communication
method employed by Ethernet, Fast Ethernet, and Gigabit Ethernet.

End Station

A workstation, server, or other device that does not forward traffic.

Ethernet

A network communication system developed and standardized by DEC, Intel, and
Xerox, using baseband transmission, CSMA/CD access, logical bus topology, and
coaxial cable. The successor IEEE 802.3 standard provides for integration into the
OSI model and extends the physical layer and media with repeaters and
implementations that operate on fiber, thin coax and twisted-pair cable.

Fast Ethernet

A 100 Mbps network communication system based on Ethernet and the CSMA/CD
access method.

Full Duplex

Transmission method that allows two network devices to transmit and receive
concurrently, effectively doubling the bandwidth of that link.

Gigabit Ethernet

A 1000 Mbps network communication system based on Ethernet and the CSMA/CD
access method.

IEEE

Institute of Electrical and Electronic Engineers.

IEEE 802.3

Defines carrier sense multiple access with collision detection (CSMA/CD) access
method and physical layer specifications.

IEEE 802.3ab

Defines CSMA/CD access method and physical layer specifications for
1000BASE-T Gigabit Ethernet. (Now incorporated in IEEE 802.3-2002.)

Glossary-3

Glossary

IEEE 802.3u

Defines CSMA/CD access method and physical layer specifications for
100BASE-TX Fast Ethernet. (Now incorporated in IEEE 802.3-2002.)

IEEE 802.3x

Defines Ethernet frame start/stop requests and timers used for flow control on
full-duplex links. (Now incorporated in IEEE 802.3-2002.)

IEEE 802.3z

Defines CSMA/CD access method and physical layer specifications for 1000BASE
Gigabit Ethernet. (Now incorporated in IEEE 802.3-2002.)

LAN Segment

Separate LAN or collision domain.

LED

Light emitting diode used for monitoring a device or network condition.

Local Area Network (LAN)

A group of interconnected computer and support devices.

Media Access Control (MAC)

A portion of the networking protocol that governs access to the transmission
medium, facilitating the exchange of data between network nodes.

MIB

An acronym for Management Information Base. It is a set of database objects that
contains information about the device.

Modal Bandwidth

Bandwidth for multimode fiber is referred to as modal bandwidth because it varies
with the modal field (or core diameter) of the fiber. Modal bandwidth is specified in
units of MHz per km, which indicates the amount of bandwidth supported by the fiber
for a one km distance.

Network Diameter

Wire distance between two end stations in the same collision domain.

Redundant Power Supply (RPS)

A backup power supply unit that automatically takes over in case the primary power
supply should fail.

Glossary

Glossary-4

RJ-45 Connector

A connector for twisted-pair wiring.

Switched Ports

Ports that are on separate collision domains or LAN segments.

TIA

Telecommunications Industry Association

Transmission Control Protocol/Internet Protocol (TCP/IP)

Protocol suite that includes TCP as the primary transport protocol, and IP as the
network layer protocol.

UTP

Unshielded twisted-pair cable.

Virtual LAN (VLAN)

A Virtual LAN is a collection of network nodes that share the same collision domain
regardless of their physical location or connection point in the network. A VLAN
serves as a logical workgroup with no physical barriers, allowing users to share
information and resources as though located on the same LAN.
