Troubleshooting
Caution When exchanging a Management Module between an E8206 zl switch and
an E8212 zl switch, the switch software must be updated. See “E8200 zl
Management Module Dependencies” on page 7 for more information.
Troubleshooting
One of 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 23 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.
