If your EX4200 switch includes an optional uplink module, you install it in the switch's
front panel. The different types of uplink modules are described in
Connector Pinout Information for EX4200 Switches" on page
The uplink module in EX4200 switches is a hot-removable and hot-insertable unit (FRU):
You can remove and replace it without powering off the switch.
NOTE: The packet forwarding process (pfem) restarts and causes traffic
loss, if you:
Install an uplink module (SFP, SFP+, SFP+ MACsec, or XFP)
Replace an existing uplink module with another uplink module
Change the operating mode of an SFP+ or SFP+ MACsec uplink module
(10-gigabit to 1-gigabit or 1-gigabit to 10-gigabit) installed in the switch
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 Setting an Uplink Port on an EX Series
Switch as a Virtual Chassis Port (CLI Procedure).
Before you begin installing an uplink module in the switch:
Ensure that you have taken the necessary precautions to prevent ESD damage (see
"Prevention of Electrostatic Discharge Damage" on page
Ensure that you have the following parts and tools available:
Electrostatic discharge (ESD) grounding strap (If a grounding strap is not available,
follow the alternative grounding method described in Step 1 of the following procedure.)
