Chapter 1 Product Overview 10/100 and 10/100/1000 Ports SFP Modules The Catalyst 3750 switch uses Gigabit Ethernet SFP modules to establish connections to other devices. These transceiver modules are field-replaceable, providing the uplink interfaces when inserted in an SFP module slot. You can use the SFP modules for Gigabit uplink connections to other switches. You use fiber-optic cables with LC or MT-RJ connectors to connect to a fiber-optic SFP module. You use a Category 5 or higher cable with RJ-45 connectors to connect to a copper SFP module. For more information about these SFP modules, see your SFP module documentation. XENPAK Module Slot (Catalyst 3750G-16TD Switch) The Catalyst 3750G-16TD switch uses 10-Gigabit Ethernet XENPAK modules to establish connections to networks. You install the modules in the module slot in the switch front panel. See Table B-2 on page B-4 for a list of XENPAK modules that the Catalyst 3750G-16TD switch supports. Note The 10-Gigabit Ethernet XENPAK modules are referred to as 10-Gigabit Ethernet module ports in the software documentation. LEDs You can use the switch LEDs to monitor switch activity and its performance. Figure 1-16, Figure 1-17, and Figure 1-18 show the switch LEDs and the Mode button that you use to select one of the port modes. All LEDs are visible through the GUI management applications-the Network Assistant application for multiple switches and the device manager GUI for a single switch. The switch software configuration guide describes how to use the command-line interface (CLI) to configure and monitor individual switches and switch clusters.
