Chapter 2: Getting to Know the Switch
Overview
16- or 24-Port 10/100/1000 Gigabit Switch with WebView
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.
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
The Back Panel
16- or 24-Port 10/100/1000 Gigabit Switch with WebView
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.
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.
Power The Power port is where you will connect the power cord.
Figure 2-2: Back Panel of the 16-Port Switch
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.
NOTE: If shared ports are both connected, then the miniGBIC port has priority.

Chapter 3: Connecting the Switch
Overview
This chapter will explain how to connect network devices to the Switch. For an example of a typical network
configuration, see the application diagram shown below.
When you connect your network devices, make sureyou don’t exceed the maximum cabling distances, which are
listed in the following table:
*A hub refers to any type of 100Mbps hub, including regular hubs and stackable hubs. A 10Mbps hub connected
to another 10Mbps hub can span up to 100 meters (328 feet).

Before You Install the Switch...
16- or 24-Port 10/100/1000 Gigabit Switch with WebView
Before You Install the Switch...
When you choose a location for the Switch, observe the following guidelines:
• Make sure that the Switch will be accessible and that the cables can be easily connected.
• Keep cabling away from sources of electrical noise, power lines, and fluorescent lighting fixtures.
• Position the Switch away from water and moisture sources.
• To ensure adequate air flow around the Switch, be sure to provide a minimum clearance of two inches
(50 mm).
• Do not stack free-standing Switches more than four units high.
Placement Options
Beforeconnecting cablesto theSwitch, first youwill physicallyinstallthe Switch.Eitherset theSwitch on itsfour
rubber feet for desktop placement or mount the Switch in a standard-sized, 19-inch wide, 1U high rack for rack-
mount placement.
Desktop Placement
1. Attach the rubber feet to the recessed areas on the bottom of the Switch.
2. Place the Switch on a desktop near an AC power source.
3. Keep enough ventilation space for the Switch and check the environmental restrictions mentioned in the
specifications.
4. Proceed to the section, “Connecting the Switch.”

16- or 24-Port 10/100/1000 Gigabit Switch with WebView
Rack-Mount Placement
To mount the Switch in any standard-sized, 19-inch wide, 1U high rack, follow these instructions:
1. Place the Switch on a hard flat surface with the front panel facing you.
2. Attach a rack–mount bracket to one side of the Switch with the supplied screws. Then attach the other
bracket to the other side.
3. Make sure the brackets are properly attached to the Switch.
4. Use the appropriate screws (not included) to securely attach the brackets to your rack.
5. Proceed to the section, “Connecting the Switch.”
Connecting the Switch
To connect network devices to the Switch, follow these instructions:
1. Make sure all the devices you will connect to the Switch are powered off.
2. For a 10/100Mbps devices, connect a Category 5 Ethernet network cable to one of the numbered ports on the
Switch. For a 1000Mbps device, connect a Category 5e Ethernet network cable to one of the numbered ports
on the Switch.
3. Connect the other end to a PC or other network device.
4. Repeat steps 2 and 3 to connect additional devices.
5. If you are using the mini-GBIC port, then connect the mini-GBIC module to the mini-GBIC port. For detailed
instructions, refer to the module’s documentation.
6. If you will use the Switch’s console interface to configure the Switch, then connect the supplied serial cable
to the Switch’s Console port, and tighten the captive retaining screws. Connect the other end to your PC’s
serial port. (This PC must be running the VT100 terminal emulation software, such as HyperTerminal.)
7. Connect the supplied power cord to the Switch’s power port, and plug the other end into an electrical outlet.
Figure 3-2: Attach the Brackets to the Switch
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.
IMPORTANT: Make sure you use the power cord that is supplied with the Switch. Use of a
different power cord could damage the Switch.
IMPORTANT: Make sure you use the screws
supplied with the mounting brackets. Using the
wrongscrews coulddamage theSwitch and would
invalidate your warranty.
