(copper) cable. This module can provide a Gigabit Ethernet connection of up to 100 meters through a Category 5 cable. Use only Cisco SFP modules on the Catalyst 2940-8TF-S switch. Each SFP module has an internal serial EEPROM that is encoded with security information. This encoding provides a way for Cisco to identify and validate that the SFP module meets the requirements for the switch.
The Cisco CWDM SFPs operate on single-mode fiber. The SFPs support both Gigabit Ethernet as well as fiber channel (1 Gigabit and 2 Gigabit) links. For more information about Cisco CWDM SFPs, see the Cisco CWDM SFP Compatibility Matrix at this URL: http://www.cisco.com/issg/tmg/cwdm.shtml#matrix...
Chapter 1 Overview Front-Panel Description All of the LEDs described in this section are visible through the GUI management applications—the Network Assistant application for multiple switches and the device manager for a single switch.
