HP Switch zl2 Modules Installation Guide

21
Troubleshooting
• If you will be installing another module in the slot, go to “Installing
the Module in an Unused Slot” on
page 10 and begin with step 2.
• If you will not install another module in the slot (that is, leave it
empty), then re-install a slot cover plate over the empty slot opening.
Caution For proper cooling and reduction of electromagnetic emissions, ensure a slot
cover is installed on any unused slot.
6. Run the command “no module <slot>” to switch configuration, if you
are exchanging one type of module with a different type of module in the
same slot.
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 14 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.
