Introduction
Benefits of Switching
Ethernet switching technology has dramatically boosted the total bandwidth of a network. It puts configuration flexibility and bandwidth adaptability into the local workgroups where the majority of work is generated. It further eliminates congestion problems inherent to the CSMA/CD protocol and improves predictable response time under heavy network loads. Expensive routing equipment was used in the past to reduce the congestion under heavy loads. The new wave of object-oriented client and server applications demands higher bandwidth and tighter integration of client workstations with servers. The old shared-access (hub/repeater) Ethernet technology provides neither enough bandwidth nor predictable response time for this new wave of workgroup computing. Fast Ethernet switching not only satisfies both technical and business requirements, but also preserves the user existing investment in the huge 10 Base-T Ethernet installed Base. This compatibility ensures a path for users to add, change, and migrate to Fast Ethernet as demands emerge. It also provides a low cost and flexible bandwidth solution directly to local workgroups where the majority of work is generated, reducing the need for expensive network equipment.

8-port Ethernet Switch
This compact switch has seven RJ-45 ports and one fiber port. Each of the RJ-45 port is capable of auto-negotiate 10/100Mbps and full or half-duplex mode. The multi­mode fiber port is able to accommodate SC connector.
The switch combines fiber and TX ports in a compact box, providing an inexpensive solution for interconnecting between buildings in a campus, multi­tenant location covering large areas or industrial environment. The fiber port provides the long distance capability and the space saving compact size makes it ideal for wall mounting or desktop.
Store-and-forward, true non-blocking architecture and auto-negotiation are features of this switch to optimize performance and value of this switch. Installation and operation involves simply plugging in cabling and connecting power. This 8-port switch represents affordable, reliable, and easy-to-use LAN solutions.

Uplink Port
An uplink port allows connection, through the TX ports, to another regular (i.e. non-uplink) port of a switch or hub. The labeled uplink port on the switch is located adjacent to port 7TX. Port 7TX & uplink-port are mutually exclusive. If port 7TX is in use, the uplink-port will be automatically disabled and vise versa.
If connecting to an uplink port of a hub or another switch, any of the regular ports can be used. To connect two regular RJ-45 ports between any two switches or hubs, you need a cross-wire cable.
DIP Switch
The DIP switch allows fixed settings. Locate the DIP switch in the back of the switch. Figure 2 summarizes these settings.
Pin 1: changes the traffic of the fiber-optic port to half­duplex when moved up to the ON position; full-duplex in the OFF position.

Pin 2: enables fixed-setting of the TX Port 1 by moving up to the ON position; activates auto-negotiation in the OFF setting. Pin 2 must be in the ON position in order to change port settings with pins 3 and 4.
Pin 3: forces 10Mbps speed on port 1 when in the ON position; forces 100Mbps speed on port 1 when in the OFF position. Note: new setting will not be activated unless fixed-setting is enabled.
Pin 4: forces half-duplex on port 1 when in the ON position; full-duplex in the OFF position. Note: new setting will not be activated unless fixed-setting is enabled.

Installation
Selecting a Site for the Switch
As with any electronic device, do not subject the Ethernet switch to extreme temperatures, humidity, or electromagnetic interference. Specifically, the site you select should meet the following requirements:
Room temperature of between 0-40°C (32­104°F)
Relative humidity of less than 90 percent, non-condensing.
Electromagnetic field (RFC) of surrounding devices not to exceed standards for IEC 801-3, Level 2 (3V/M) field strength.
Adequate ventilation. Do not block the ventilation holes on the side of the switch or the fan exhaust port on the rear of the switch.
Power outlet located within 1.8Meter of the switch.
User’s Manual 9
Page 10
Connecting to Power
Connect the supplied AC power cord to the receptacle on the back of the switch, and then plug the cord into a standard AC outlet with a voltage range from 100 to 240 VAC.
Turn on the switch by flipping the ON/OFF switch on the rear of the unit to the I (ON) position. The O position is OFF.
Connecting to Your Network
Consult Table 1 for specific cabling requirements. Prepare cable with connections corresponding to the port. Install the same type of connectors at both ends for proper performance. With the power switch in the OFF position, connect the cables. No further installation is necessary.

Appendix B - Introduction to LAN
& Ethernet Technologies
As communication and business applications become increasingly complex, computer networking has evolved as a very important part of the infrastructure.
Communication systems like Local Area Network (LAN) evolved into sophisticated, powerful, yet flexible technology. Among the different types of LAN technologies, Ethernet represents the best in speed, cost, ease of installation, and supportability.
LAN
Local Area Network (LAN) technology gave personal computers the power to share resources of hardware and software. LAN connects personal computers, file servers, printers, etc. together within a geographical area, usually a single building. Multiple, widely dispersed LAN systems are referred to as a wide area network (WAN).
Ethernet Technologies
More than 80 percent of all LANs utilize Ethernet technology. The Institute of Electrical and Electronic Engineers (IEEE) standardized Ethernet in IEEE 802.3, which provides for configuration rules, interaction requirements, types of media, and data rate.
User’s Manual 16
Page 17
Fast Ethernet
For networks that need higher transmission speeds, a faster speed was developed and IEEE next established IEEE 802.3u, raising the Ethernet speed from 10Mbps to 100Mbps. Thus, fast Ethernet arose and users quickly began converting from 10Mbps to 100Mbps.
Gigabit Ethernet
The demand for even higher speed created the gigabit Ethernet at 1000Mbps (or 1Gbps). The newer IEEE standard for gigabit Ethernet is IEEE 802.3z. The only cabling media approved is the fiber-optic pair. The IEEE has already begun discussions to standardize 10Gbps (“10Gig”) Ethernet.
Ethernet Products
Hub
One of the earlier connection solutions for Ethernet, a hub (also called a repeater) operates by broadcasting data to all ports simultaneously, and repeating the process until the data is received by the intended node. The hub works through a “shared network” with all of the nodes in the network segment sharing the same collision domain. Switches and bridges emerged because of a need to separate collision domains that are too large, therefore improving performance and network reliability.
User’s Manual 17
Page 18
Switch
A switch solves the collision problem by working as a single domain. A Switch maps the physical Ethernet addresses of the nodes residing on each network segment and then allows only the necessary traffic to pass through. Packets of data are transmitted along with the destination and source segment.
There are two basic architectures of LAN switches, cut­through and store-and-forward. Cut-through switches consider only the destination address before forwarding it on to its destination segment, but store-and-forward architecture accepts and then analyzes the entire packet before forwarding. This allows the switch to stop certain packet errors from propagating through the network. The store-and forward switch eliminates redundant or corrupted packets, thus increasing the efficiency of the network transmission.
