Removing an Uplink Module from an EX3200 or EX4200 Switch
If your EX3200 or EX4200 switch includes an optional uplink module, it is installed in the
switch's front panel. The different types of uplink modules are described in “Uplink
Modules in EX3200 and EX4200 Switches” on page 34.
Theuplink module in EX3200 and EX4200 switchesis a hot-removable and hot-insertable
unit (FRU): You can remove and replace it without powering off the switch or disrupting
switch functions.
NOTE: If you have set an uplink module port as a Virtual Chassis port (VCP), removing
the uplink module breaks the setting. You must reset the port as a VCP after you replace
the module. See Settingan Uplink ModulePortasa Virtual Chassis Port (CLI Procedure).
Before you begin removing an uplink module from an EX3200 or EX4200 switch:
•
Ensure that you have taken the necessary precautions to prevent ESD damage (see
“Prevention of Electrostatic Discharge Damage on EX Series Switches” on page 236).
