Installing an Uplink Module in an EX4300 Switch
You can install an uplink module in the front panel of an EX4300 switch. The uplink
module in EX4300 switches is a hot-removable and hot-insertable unit (FRU): You can
remove and replace it without powering off 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 313).
Ensure that you have the following parts and tools available:
•
Electrostatic discharge (ESD) grounding strap (If a grounding strap is not available,
follow the alternativegrounding method described in Step 1 of the following procedure.)
•
Phillips (+) screwdriver, number 2
