UL Warning
a) Elevated Operating Ambient Temperature- If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an envi­ronment compatible with the manufacturer’s maximum rated ambi­ent temperature (Tmra).
b) Reduced Air Flow- Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.
c) Mechanical Loading- Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.
d) Circuit Overloading- Consideration should be given to the con­nection of the equipment to the supply circuit and the effect that overloading of circuits might have on over current protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
e) Reliable Earthing- Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (e.g., use of power strips).

Introduction
This chapter describes the features of the Switch and some back­ground information about Ethernet/Fast Ethernet/Gigabit Ethernet switching technology.
Fast Ethernet Technology
The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high perfor­mance networks. A number of high-speed LAN technologies have been proposed to provide greater bandwidth and improve client/ server response times. Among them, 100BASE-T (Fast Ethernet) provides a non-disruptive, smooth evolution from the current 10BASE-T technology. The non-disruptive and smooth evolution nature, and the dominating potential market base, virtually guarantee cost-effective and high performance Fast Ethernet solutions.
100Mbps Fast Ethernet is a standard specified by the IEEE 802.3 LAN committee. It is an extension of the 10Mbps Ethernet standard with the ability to transmit and receive data at 100Mbps, while maintaining the CSMA/CD Ethernet protocol. Since the 100Mbps Fast Ethernet is compatible with all other 10Mbps Ethernet envi­ronments, it provides a straightforward upgrade and takes advantage of the existing investment in hardware, software, and personnel train­ing.

Gigabit Ethernet Technology
Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, and support for CSMA/CD proto­col, full duplex, flow control, and management objects, but with a tenfold increase in theoretical throughput over 100-Mbps Fast Ethernet and a hundredfold increase over 10-Mbps Ethernet. Since it is compatible with all 10-Mbps and 100-Mbps Ethernet environ­ments, Gigabit Ethernet provides a straightforward upgrade without wasting a company’s existing investment in hardware, software, and trained personnel. The increased speed and extra bandwidth offered by Gigabit Ethernet are essential to coping with the network bottlenecks that frequently develop as computers and their busses get faster and more users using applications that generate more traffic. Upgrading key compo­nents, such as your backbone and servers to Gigabit Ethernet can greatly improve network response times as well as significantly speed up the traffic between your subnets. Gigabit Ethernet supports video conferencing, complex imaging, and similar data-intensive applications. Likewise, since data transfers occur 10 times faster than Fast Ethernet, servers outfitted with Giga­bit Ethernet NIC’s are able to perform 10 times the number of opera­tions in the same amount of time. The phenomenal bandwidth delivered by Gigabit Ethernet was the most cost-effective method to take advantage of today’s rapidly improving switching and routing internetworking technologies. And with expected advances in silicon technology and digital signal pro­cessing that enabled Gigabit Ethernet to eventually operate over unshielded twisted-pair (UTP) cabling, outfitting your network with a powerful 1000-Mbps-capable backbone/server connection creates a flexible foundation for the next generation of network technology products.

Switching Technology
Another approach to pushing beyond the limits of Ethernet technol­ogy is the development of switching technology. A switch bridges Ethernet packets at the MAC address level of the Ethernet protocol transmitting among connected Ethernet or Fast Ethernet LAN seg­ments.
Switching is a cost-effective way of increasing the total network capacity available to users on a local area network. A switch in­creases capacity and decreases network loading by dividing a local area network into different segments, which don’t compete with each other for network transmission capacity.
The switch acts as a high-speed selective bridge between the indi- vidual segments. The switch, without interfering with any other segments, automatically forwards traffic that needs to go from one segment to another. By doing this the total network capacity is multiplied, while still maintaining the same network cabling and adapter cards.
Switching LAN technology is a marked improvement over the previ­ous generation of network bridges, which were characterized by higher latencies. Routers have also been used to segment local area net­works, but the cost of a router, the setup and maintenance required make routers relatively impractical. Today switches are an ideal solution to most kinds of local area network congestion problems.

Unpacking and Installation
This chapter provides unpacking and installation information for the Switch. To avoid causing any damage to the Switch, we recommend that you read this chapter carefully before starting installation.
Unpacking
Open the shipping carton of the Switch and carefully unpack the items inside. The carton should contain the following items:
One 26-Port 10/100/1000Mbps Gigabit & Ethernet
Switch
One AC power cord, suitable for your area’s electrical
power connections
Four rubber feet to be used for shock cushioning Screws and two mounting brackets User’s Guide
If any item is found missing or damaged, please contact your local reseller for replacement.

Installation
The site where you place the Switch may greatly affect its perfor­mance. When installing, take the following into your consideration:
Install the Switch in a fairly cool and dry place. See
Technical Specifications for the acceptable temperature and humidity operating ranges.
Install the Switch in a site free from strong electromag-
netic field generators (such as motors), vibration, dust, and direct exposure to sunlight.
Leave at least 10cm of space at the front and rear of the
hub for ventilation.
Install the Switch on a sturdy, level surface that can
support its weight, or in an EIA standard-size equipment rack. For information on rack installation, see the next section, Rack Mounting.
When installing the Switch on a level surface, attach the
rubber feet to the bottom of each device. The rubber feet cushion the hub and protect the hub case from scratch­ing.

Rack Mounting
The Switch can be mounted in an EIA standard-size, 19-inch rack, which can be placed in a wiring closet with other equipments. Attach the mounting brackets to both sides of the Switch (one at each side), and secure them with the provided screws.
Figure 2. Combine the Switch with the provided screws
Then, use screws provided with the equipment rack to mount the Switch in the rack.

Connecting Network Cable
The Switch supports 10/100/1000Mbps Gigabit Ethernet. It runs full/half duplex transfer mode for 10/100Mbps and full duplex trans­fer mode for 1000Mbps.
These ports are Auto-MDI type port. The Switch can auto trans­form to MDI-II or MDI-X type, so you can just make an easy connection that without worrying if you are using a standard or crossover cable.
AC Power
The Switch can be used with AC power supply 100-240VAC, 50-60 Hz. The power switch is located at the rear of the unit adjacent to the AC power connector and the system fan. The switch’s power sup­ply will adjust to the local power source automatically and may be turned on without having any or all LAN segment cables connected.
