• The status indicator turns green when the switch and the target device
have an established link.
• The status indicator turns amber while the SFP module discovers the
network topology and searches for loops. This process takes about 30
seconds, then the port status indicator turns green.
• If the status indicator is off, the target device might not be turned on,
there might be a cable problem, or there might be problem with the
adapter installed in the target device. See Chapter 3, Troubleshoot the
Switch for solutions to cabling problems.
5. If necessary, restart the switch or the target device.
