Chapter 1 Product Overview
Front Panel Description
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 Category 5 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
The Catalyst 3750G-16TD switch uses 10-Gigabit Ethernet XENPAK modules to
establish connections to networks. The modules are installed in the module slot in
the switch front panel.
For a list of the XENPAK modules that the Catalyst 3750G-16TD switch
supports, see the Catalyst 3750 release notes. For more information about
XENPAK modules, see your XENPAK module documentation.
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 1-13 shows the Catalyst 3750 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.
