1.4 Glossary
10BASE-T
IEEE 802.3 specification for 10 Mbps Ethernet over two pairs of Category 3, 4, or 5 UTP cable.
100BASE-TX
IEEE 802.3u specification for 100 Mbps Fast Ethernet over two pairs of Category 5 UTP cable.
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.
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.
Auto-negotiation
Signalling method allowing each node to select its optimum operational mode (e.g., 10 Mbps or
100 Mbps and half or full duplex) 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.

8
CSMA/CD
Carrier Sense Multiple Access/Collision Detect is the communication method employed by
Ethernet and Fast Ethernet.
Full Duplex
Transmission method that allows switch and network card to transmit and receive concurrently,
effectively doubling the bandwidth of that link.
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.
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, and allows users to share information and resources as though
located on the same LAN.
IEEE 802.1Q
VLAN Tagging—Defines Ethernet frame tags which carry VLAN information. It allows
switches to assign endstations to different virtual LANs, and defines a standard way for VLANs to
communicate across switched networks.
IEEE 802.1p
An IEEE standard for providing quality of service (QoS) in Ethernet networks. The standard
uses packet tags that define up to eight traffic classes and allows switches to transmit packets based
on the tagged priority value.
Port Mirroring
A method whereby data on a target port is mirrored to a monitor port for troubleshooting with a
logic analyzer or RMON probe. This allows data on the target port to be studied unobstructively.
Bandwidth Control
This function allows the network manager to control the maximum rate for traffic transmitted
or received on an interface. Rate limiting is configured on interfaces at the edge of a network to
limit traffic into or out of the network. Traffic that falls within the rate limit is transmitted, while
packets that exceed the acceptable amount of traffic are dropped.

9
IGMP Snooping
Listening to IGMP Query and IGMP Report packets transferred between IP Multicast Routers
and IP Multicast host groups to identify IP Multicast group members.
Internet Group Management Protocol (IGMP)
A protocol through which hosts can register with their local router for multicast services. If there
is more than one multicast router on a given subnetwork, one of the routers is made the “querier”
and assumes responsibility for keeping track of group membership.

2.2 Hardware Connection
The power receptacle is located on the rear panel of the switch. The standard power receptacle is
for the AC power cord.
The Switch contains 24 10BASE-T /
100BASE-TX RJ-45 ports. All of these 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. Each of these ports also support
auto-negotiation, so the optimum transmission mode (half or full duplex), and data rate (10 or 100
Mbps) can be selected automatically.
See the following section to get more details about connection of RJ-45 ports.
Connecting to PC or Server
You can connect any RJ-45 station port
on the Switch to a PC via twisted-pair cable
with RJ-45 plugs at both ends. Use Category
3, 4 or 5 cable for standard 10Mbps
Ethernet connections, or Category 5 cable
for 100Mbps Fast Ethernet connections.
Make sure you have installed a
10BASE-T or 100BASE-TX network
interface card for connecting a PC to the
Switch’s RJ-45 (MDI-X) station ports. If
LEDs don’t light afterpowering on the Switch, check if the LAN card, the cable and connectors are
properly attached to the PC and the Switch. When a attached PC is powered on or reset:
1. The Link/Act LED will light
2. The FDX/Col LED depends on the installed LAN card’s capabilities for the PC and the Switch
connection.
3. The 100M LED will light for 100Mbps connection, otherwise it will be unlighted.
