The 16 Port and 24-Port 10/100/1000 Gigabit Switches provide non-blocking, wire speed switching for your 10, 100, and 1000 megabit network clients. Drop this switch in place of your current workgroup hub or switch, and you can upgrade your high-requirement workstations to full Gigabit speeds as necessary, while continuing to service other clients at their current speeds. Or build your network from the ground up, with appropriate link speeds for each user's requirements. Either way, it's perfect for graphics, multimedia, and other applications that have to move large files across the network quickly. And when you need to expand your network even further, the SR2024C has two Mini-GBIC ports that let you add fiber-optic capability easily and cost effectively. With the 16-Port or 24-Port 10/100/1000 Gigabit Switch, you can connect your existing 10/100 Ethernet network to a Gigabit server backbone without any additional equipment. All ports have automatic MDI/MDI-X crossover detection, so you don't have to worry about the cable type. Each port independently and automatically negotiates for best speed and whether to run in half- or full-duplex mode. Address learning and aging is supported, as well as 802.3x flow control with head-of-line blocking prevention to keep your high-speed clients from bogging down in lower-speed traffic. Fast store-and-forward switching prevents damaged packets from being passed on into the network. World famous Linksys reliability and the limited lifetime warranty give you peace of mind and the rackmount form factor integrates smoothly into your network infrastructure. Let the Linksys 16-Port or 24-Port 10/100/1000 Gigabit Switch kick your network into high gear. This user guide will give you all the information you need to connect, set up, and configure your Switch.

For an example of a typical network configuration, see the application diagram shown in Figure 3-1. Internet Cable/DSL Modem Router Wireless Access Point Server Desktop Notebook Figure 3-1: Example of a Typical Network (SR2024C) Chapter 3: Connecting the Switch Overview 6 16-Port or 24-Port 10/100/1000 Gigabit Switch When you connect your network devices, make sure you don't exceed the maximum cabling distances, which are listed in the following table: Table 1: Maximum Cabling Distances From Switch Hub Switch or Hub Switch or Hub* Hub Computer To Maximum Distance 100 meters (328 feet) 5 meters (16.4 feet) 100 meters (328 feet) 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). Connection Instructions 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. Connect a Category 5 Ethernet network cable to one of the numbered ports on the Switch. 3. Connect the other end to a PC or other network device. NOTE: Use Category 5e Ethernet cables for your Gigabit connections. 4. Repeat steps 2 and 3 to connect additional devices. NOTE: The miniGBIC ports are shared and are only located on the SR2024C. Do not use port 12, if you are using the miniGBIC 1 port. If you are using miniGBIC port 2, do not use port 24. For instructions on how to connect miniGBIC modules to the Switch's miniGBIC ports, please refer to the module's documentation. 5. Connect the supplied power cord to the Switch's power port, and plug the other end into an electrical outlet. 6. Power on the devices connected to the Switch. Each active port's corresponding LED will light up on the Switch. Figure 3-2: Connecting an Ethernet Cable Chapter 3: Connecting the Switch Connection Instructions 7 16-Port or 24-Port 10/100/1000 Gigabit Switch Placement Options There are three ways to physically install the Switch: set the Switch on its four rubber feet, mount the Switch in a standard-sized, 1U high rack, or hang the Switch on a wall using its wall-mount slots. To rack mount the Switch, follow these instructions: 1. The Switch has four mounting holes on each side. Screw an included mounting bracket into each side. 2. Place the Switch in the rack, and secure the brackets with additional screws. To hang the Switch on a wall, follow these instructions: 1. The wall-mount slots are two crisscross slots on the Switch's bottom panel (see Figure 3-3). The distance between the two slots is 95 mm. Attach two screws to the wall, so that the Switch's wall-mount slots line up with the two screws. 2. Maneuver the Switch so the screws are inserted into the two slots. Congratulations!The installation of the Switch is complete.
