Removing an Uplink Module from an EX4300 Switch
The uplink module in EX4300 switches is hot-removable and hot-insertable
field-replaceable unit (FRU): You can remove and replace it without powering off the

Before you begin removing an uplink module from the switch:
•
Ensure that you have taken the necessary precautions to prevent electrostatic discharge
(ESD) damage (see “Prevention of Electrostatic Discharge Damage” on page 313).
