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 section describes the features of the 24-Port 1000BASE-T Gigabit Ethernet Switch, as well as giving some background information about Gigabit Ethernet and switching technology.
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 is essential to coping with the network bottlenecks that frequently develop as computers and their busses get faster and more users use 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.
6
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.
Switching Technology
Another key development pushing the limits of Ethernet technology is in the field 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 making it possible for a local area network to be divided into different segments which don’t compete with each other for network transmission capacity, giving a decreased load on each.
The switch acts as a high-speed selective bridge between the individual segments. Traffic that needs to go from one segment to another is automatically forwarded by the switch, without interfering with any other segments. This allows the total network capacity to be multiplied, while still maintaining the same network cabling and adapter cards.
7
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 and the setup and maintenance required make routers relatively impractical. Today’s switches are an ideal solution to most kinds of local area network congestion problems.

Unpacking and Setup
This chapter provides unpacking and setup information for the Switch.
Unpacking
Open the shipping carton of the Switch and carefully unpack its contents. The carton should contain the following items:
One 24-Port 1000BASE-T Gigabit Ethernet Switch Accessory pack: 2 mounting brackets and screws Four rubber feet with adhesive backing One AC power cord This User’s Guide
If any item is found missing or damaged, please contact your local reseller for replacement.
Setup
The setup of the Switch can be performed using the following steps:
The surface must support at least 5 kg. The power outlet should be within 1.82 meters (6 feet)
of the device.
9
Visually inspect the power cord and see that it is
secured fully to the AC power connector.
Make sure that there is proper heat dissipation from
and adequate ventilation around the Switch. Do not place heavy objects on the Switch.
Desktop Installation
When installing the Switch on a desktop or shelf, the rubber feet included with the device must be first attached. Attach these cushioning feet on the bottom at each corner of the device. Allow enough ventilation space between the device and the objects around it.

LED Indicators
The LED indicators of the Switch include Power, Link/Act, 1000Mbps and 100Mbps. The following shows the LED indicators for the Switch along with an explanation of each indicator.
The Switch LED indicators
Per unit:
Power This indicator lights green when the Switch is
receiving power, otherwise, it is off.
Per port:
Link/ACT. This indicator light green when the port is
connected to a Gigabit Ethernet, Fast Ethernet or Ethernet station, if the indicator blinking green will be transmission or received data.
1000Mbps. This LED indicator light green when the
port is connected to a 1000Mbps Gigabit Ethernet station.
100Mbps. This LED indicator light green when the
port is connected to a 100Mbps Fast Ethernet station.
Note: If the Link/ACT LED indicator light green and
both of 1000Mbps and 100Mbps LED indicators off, mean the port is connecting to 10Mbps Ethernet station.
