NOTE: If you have a Juniper J-Care service contract, register any addition,
change, or upgrade of hardware components at
https://www.juniper.net/customers/csc/management/updateinstallbase.jsp .
Failure to do so can result in significant delays if you need replacement parts.
This note applies if you change the type of power supply or add a new type
of uplink module. It does not apply if you replace these components with the
same type of component.

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
switch or disrupting switch functions.
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 299 ).
•
If there are any transceivers installed in the uplink module, remove them before you
remove the uplink module. For instructions on removing transceivers, see
“Removing
a Transceiver from a Switch” on page 237 .
Ensure that you have the following parts and tools available:
• ESD grounding strap
•
Phillips (+) screwdriver, number 2
•
A replacement uplink module or cover panel
• An antistatic bag or antistatic mat
