Chapter 2: Getting to Know the Switch

Overview
The 16- and 24-Port Switches differ in number of LEDs and ports. Pictured in this chapter is the 16-Port Switch; however, the other Switch is similar in form and function.
The Front Panel
The Switch's LEDs and ports are located on the front panel.
Figure 2-1: Front Panel of the 16-Port Switch
LEDs
SYSTEM Green. The SYSTEM LED lights up to indicate that the Switch is powered on. Link/Act Green. The Link/Act LED lights up to indicate a functional network link through the
corresponding port (1 through 16 or 1 through 24) with an attached device. It flashes to indicate that the Switch is actively sending or receiving data over that port.
Gigabit Orange. The Gigabit LED lights up to indicate a Gigabit connection on the corresponding
port (1 through 16 or 1 through 24).
Ports
1-24 The Switch is equipped with 16 or 24 auto-sensing, Ethernet network ports, which use RJ-
45 connectors. These ports support network speeds of 10Mbps, 100Mbps, and 1000Mbps. They can operate in half and full-duplex modes. Auto-sensing technology enables each port to automatically detect the speed of the device connected to it (10Mbps, 100Mbps, or 1000Mbps), and adjust its speed and duplex accordingly.
Chapter 2: Getting to Know the Switch Overview
3
For the 16-Port Switch, ports 8 and 16 are shared with miniGBIC1 and miniGBIC2, respectively. For the 24-Port Switch, ports 12 and 24 are shared with miniGBIC1 and miniGBIC2, respectively.
NOTE: If shared ports are both connected, then the miniGBIC port has priority.
miniGBIC1/2 The Switch provides two mini-GBIC ports. The mini-GBIC (gigabit interface converter) port
is a connection point for a mini-GBIC expansion module, so the Switch can be uplinked via fiber to another switch. Each mini-GBIC port provides a link to a high-speed network segment or individual workstation at speeds of up to 1000Mbps.
Use the Linksys MGBT1, MGBSX1, or MGBLH1 mini-GBIC modules with the Switch. The MGBSX1 and the MGBLH1 require fiber cabling with LC connectors, while the MGBT1 requires a Category 5e Ethernet cable with an RJ-45 connector.
Console The Console port is where you can connect a serial cable to a PC’s serial port for
configuration using your PC’s HyperTerminal program. Refer to “Chapter 4: Using the Console Interface for Configuration” for more information.
The Back Panel
The power port is located on the back panel of the Switch.
Figure 2-2: Back Panel of the 16-Port Switch
Power The Power port is where you will connect the power cord.
NOTE: If you need to reset the Switch, unplug the power cord from the back
of the Switch. Wait a few seconds and then reconnect it.

Appendix A: About Gigabit Ethernet and Fiber Optic Cabling

Gigabit Ethernet
Gigabit Ethernet runs at speeds of 1Gbps (Gigabit per second), ten times faster than 100Mbps Fast Ethernet, but it still integrates seamlessly with 100Mbps Fast Ethernet hardware. Users can connect Gigabit Ethernet hardware with either fiber optic cabling or copper Category 5e cabling, with fiber optics more suited for network backbones. As the Gigabit standard gradually integrates into existing networks, current computer applications will enjoy faster access time for network data, hardware, and Internet connections.
Fiber Optic Cabling
Fiber optic cabling is made from flexible, optically efficient strands of glass and coated with a layer of rubber tubing, fiber optics use photons of light instead of electrons to send and receive data. Although fiber is physically capable of carrying terabits of data per second, the signaling hardware currently on the market can handle no more than a few gigabits of data per second.
Fiber cables come with two main connector types. The most commonly used fiber optic cable is multi-mode fiber cable (MMF), with a 62.5 micron fiber optic core. Single-mode fiber cabling is somewhat more efficient than multi-mode but far more expensive, due to its smaller optic core that helps retain the intensity of traveling light signals. A fiber connection always require two fiber cables: one transmits data, and the other receives it.
Each fiber optic cable is tipped with a connector that fits into a fiber port on a network adapter , hub, or switch. In the USA, most cables use a square SC connector that slides and locks into place when plugged into a port or connected to another cable. In Europe, the round ST connector is more prevalent.
You must use the Linksys MGBT1, MGBSX1, or MGBLH1 mini-GBIC modules with the Linksys Gigabit Switches. The MGBSX1 and the MGBLH1 require fiber cabling with LC connectors, and the MGBT1 requires a Category 5e Ethernet cable with an RJ-45 connector.
