Chapter 1: Introduction What's in this User Guide? 2 WebView Switches Chapter 2: Getting to Know the Switch Overview The Switches differ in number and types of LEDs and ports. While the 16-Port Gigabit Ethernet Switch is pictured in this chapter, the other Switches are 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 Link/Act Green. The SYSTEM LED lights up to indicate that the Switch is powered on. Green. The Link/Act LED lights up to indicate a functional network link through the corresponding port (1 through 16, 24, or 48) with an attached device. It flashes to indicate that the Switch is actively sending or receiving data over that port. Orange. The Gigabit LED lights up to indicate a Gigabit connection on the corresponding port (1 through 16, 24, or 48). Gigabit Ports 1-48 The Switch is equipped with 16, 24, or 48 auto-sensing, Ethernet network ports, which use RJ-45 connectors. The Fast Ethernet ports support network speeds of 10Mbps or 100Mbps, while the Gigabit Ethernet 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. 3 Chapter 2: Getting to Know the Switch Overview WebView Switches For the 16-Port Switch, ports 8 and 16 are shared with miniGBIC1 and miniGBIC2, respectively. For the 24-Port Gigabit Ethernet 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.
