Install SFP Modules and Connect to the Module PortsThe switch Gigabit Ethernet SFP modules are used for connections to other devices. These transceivermodules are field-replaceable, providing the uplink interfaces when inserted in an SFP module slot.You can use any combination of SFP modules. See the switch release notes for the list of SFP modulesthat the switch supports.To install an SFP module, position the module in front of the module slot. Insert the SFP module intothe slot until you feel the connector on the module snap into place.202373After installing the SFP module, use fiber-optic cables with LC or MT-RJ connectors to connect to afiber-optic SFP module. Use a Category 5 or higher cable with RJ-45 connectors to connect to a copperSFP module. For detailed instructions on installing, removing, and cabling the SFP module, see yourSFP module documentation.Use only <strong>Cisco</strong> SFP modules with the switch. Each SFP module has an internal serial EEPROM that isencoded with security information. This encoding provides a way for <strong>Cisco</strong> to identify and validatethat the SFP module meets the requirements for the switch.Verify Port ConnectivityAfter you connect a device to the switch port, the port LED turns amber while the switch establishesa link. This process takes about 30 seconds. Then the LED turns green when the switch and theattached device have an established link. If the LED is off, the device might not be turned on, theremight be a cable problem, or there might be a problem with the adapter installed in the device. See the“In Case of Difficulty” section on page 20 for information about online assistance.19
