Troubleshooting

One of the primary tools for troubleshooting the switch modules is the LEDs
on the front of the switch and on the modules. Refer to "LED Behavior" on
page 12 for a description of the normal LED behavior. Also, refer to the switch
Installation and Getting Started Guide for more detailed troubleshooting
information for the switch.
