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
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.)
Phillips (+) screwdriver, number 2
To install an uplink module in the switch (see
and Figure 76 on page 231):
Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and
1.
connect the strap to the ESD point on the chassis.
If a grounding strap is not available, hold the uplink module in its antistatic bag in one
hand and touch the exposed, bare metal of the switch with the other hand to ground
yourself and the component.
If the uplink module slot has a cover panel on it, loosen both captive screws on the
