Sfp Module Patch Cable; Leds; System Led; Power Supply Leds (Only Cisco Me 3400G-12Cs Switches) - Cisco ME 3400 Hardware Installation Manual

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.
