Cisco Systems Cisco ME 3400 manual LEDs, SFP Module Patch Cable, System LED

Chapter 1 Product Overview

Front Panel Description

Use only Cisco SFP modules on your switch. Each SFP module has an internal serial electrically erasable programmable read-only memory (EEPROM) that is encoded with security information. This encoding provides a way for Cisco to identify the module and to ensure that it meets the performance, quality, and interoperability requirements for the device.

For information about Cisco SFP modules, see the documentation at this URL:

SFP Module Patch Cable

The Cisco ME switch supports the SFP module patch cable, a 0.5-meter, copper, passive cable with SFP module connectors at each end (see Figure 1-7). The patch cable connects two Cisco ME switches in a cascaded configuration.

See the “Inserting and Removing the SFP Module Patch Cable” section on page 2-19for more information about using the SFP module patch cable.

On the Cisco ME-3400-24FS-A switch, only the Gigabit Ethernet uplink ports support the SFP module patch cable.

You can order the SFP module patch cable (part number CAB-SFP-50CM=).
