Chapter 1: Introduction Gigabit Ethernet technology Gigabit Ethernet is an extension of IEEE 802.3 Ethernet. It uses the same packet structure, format, and support for CSMA/CD protocol, full duplex, and flow control, but with a tenfold increase in theoretical throughput over 100-Mbps Fast Ethernet and a hundredfold increase over 10-Mbps Ethernet. Because it is compatible with all 10-Mbps and 100-Mbps Ethernet environments, Gigabit Ethernet provides a straightforward upgrade without wasting

Switch descriptions For Fast Ethernet or Gigabit Ethernet networks, a switch is an effective way of eliminating problems of chaining hubs beyond the “two-repeater limit.” A switch can be used to split parts of the network into different collision domains, for example, making it possible to expand your Fast Ethernet network beyond the 205-meter network diameter limit for 100BASE-TX networks. Switches supporting both traditional 10Mbps Ethernet and 100Mbps Fast Ethernet are also ideal for br

Chapter 1: Introduction ■ Supports 2M bits data buffer per device. ■ Front-panel indicator LEDs. Front-panel components The front panels of the switches consist of LED indicators and fast Ethernet or gigabit Ethernet ports. The number of LEDs, and the number and speed of the ports, depends on the switch model selected. Comprehensive LED indicators display the status of the switches and the network.

Link/Act This indicator lights green when the port is connected to a Gigabit Ethernet, Fast Ethernet, or Ethernet station. If the indicator is blinking green, data is either being transmitted or received. Speed This LED indicator is dark when the port is connected

Chapter 1: Introduction Side panel description The sides of the system provide heat vents that help to dissipate heat. Do not block these openings, and leave at least 6 inches (152.3 mm) of space at the rear and sides of the switch for correct ventilation. Warning Without correct heat dissipation and air circulation, system components might overheat, which could lead to system failure. www.gateway.com 8

Chapter 2: Installation Before you connect to the network The site where you install the switch may greatly affect its performance. Please follow these guidelines for setting up the switch: ■ Install the switch on a sturdy, level surface that can support at least 6.6 lbs. (3 kg) of weight. Do not place heavy objects on the switch. ■ The power outlet should be within 6 feet (1.82 meters) of the switch. ■ Visually inspect the power cord and see that it is fully secured to the AC power port. ■ M

Chapter 2: Installation Installing the 16- and 24-port switches in a rack The switch can be mounted in a standard 19” rack. Use the following illustrations to guide you. Warning Before attaching rack mounting hardware, make sure that the switch is turned off and all power cords are unplugged. Warning The rack cabinet must provide sufficient airflow to the front of the switch to maintain correct cooling. It must also include ventilation sufficient to exhaust the heat generated by the equip
