Install SFP Modules and Connect to the Module Ports
The switch Gigabit Ethernet SFP modules are used for connections to other devices. These 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 14 for information about online assistance.

In Case of Difficulty
If you experience difficulty, help is available in this section and also on Cisco.com. This section includes Express Setup
troubleshooting, how to reset the switch, how to access help online, and where to find more information.
Troubleshooting Express Setup
If Express Setup does not run, or if the Express Setup page does not appear in your browser:
Did you verify that POST ran successfully before starting
Express Setup?
Did you press the Mode button while the switch was still
running POST?
Did you try to continue without confirming that the switch
was in Express Setup mode?

If not, make sure that only the SYST and STAT LEDs are green
before you press the Mode button to enter the Express Setup
mode.
POST errors are usually fatal. Contact your Cisco technical
support representative if your switch fails POST.
If yes, wait until POST completes. Power cycle the switch. Wait
until POST completes. Confirm that the SYST and STAT LEDs
are green. Press the Mode button to enter Express Setup mode.
Verify that all LEDs above the Mode button are green. (The
RPS LED is off.) If necessary, press the Mode button to enter
Express Setup mode.
