1.4 Glossary
10BASE-T
IEEE 802.3 specification for 10 Mbps Ethernet over two pairs of Category 3, 4, or 5 UTPcable.
100BASE-TX
IEEE 802.3u specification for 100 Mbps Fast Ethernet over two pairs of Category 5 UTPcable.
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.

2D
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.
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.

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.
IGMP Snooping
Listening to IGMP Query and IGMP Report packets transferred between IP Multicast Routers
and IP Multicast host groups to identify IPMulticast 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
cablewith RJ-45 plugs at both ends. Use
Category 3, 4 or 5 cable for standard
10MbpsEthernet connections, or Category 5
cable for 100Mbps Fast Ethernet
connections.
Make sure you have installed a
10BASE-T or 100BASE-TX network
interface card forconnecting 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 properlyattached to the PC and the Switch.

3. COM port configuration
In this chapter, you will be provided with detailed information on how to set up the 24-Port
100/10M N-Way Rack-Mount Smart Switch through a PC terminal emulation program. Aterminal
program is required to communicate with the switch’s internal software. Only after the terminal
program setup is done, you are thus able to proceed to set up the 24-Port 100/10M N-Way
Rack-Mount Smart Switch .
Before you are able to access the 24-Port 100/10M N-Way Rack-Mount Smart Switch 24-Port
100/10M N-Way Rack-Mount Smart Switch , you have to configure your terminal emulation
program. Windows O/S provides a suitable program called “Hyper Terminal” for configuration, or
you can choose other third-party products such as “Telix and ProCom” instead.
Connect a RJ-45 Cable to a COM port on your PC and to the console port of your Smart Switch
as the below figure.
