Install SFP Modules and Connect to the Module Ports

The switch Gigabit Ethernet SFP modules are used for connections to other devices. These transceiver

modules 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 modules

that the switch supports.

To install an SFP module, position the module in front of the module slot. Insert the SFP module into

the slot until you feel the connector on the module snap into place.

After installing the SFP module, use fiber-optic cables with LC or MT-RJ connectors to connect to a

fiber-optic SFP module. Use a Category 5 or higher cable with RJ-45 connectors to connect to a copper

SFP module. For detailed instructions on installing, removing, and cabling the SFP module, see your

SFP module documentation.

Use only Cisco SFP modules with the 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.

Verify Port Connectivity

After you connect a device to the switch port, the port LED turns amber while the switch establishes

a link. This process takes about 30 seconds. Then the LED turns green when the switch and the

attached device have an established link. If the LED is off, the device might not be turned on, there

might 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.
