Troubleshooting

The primary tools for troubleshooting the switch modules are the LEDs on the
front of the switch and on the modules. Refer to “LED Behavior” on

page 8

Also, refer to the

Installation and Getting Started Guide

for more detailed

troubleshooting information.

The following tables describe switch and module LED displays that indicate
that the module or connections to the ports on the module are not operating
correctly.
