Cisco Cisco Catalyst Switch Module 3012 for IBM BladeCenter Installation Guide

After you connect a device to a switch module port, the port LED is off while the switch module 
establishes a link. This process takes about 30 seconds. Then the LED turns green when the switch 
module 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 26 for more information.

If you experience difficulty, help is available in this section and also on Cisco.com. You can access the 
Cisco Technical Support and Documentation website for a list of known hardware problems and 
extensive troubleshooting documentation at:
