Removing an Expansion Module from a QFX5100 Switch
The QFX-EM-4Q expansion modules used in QFX5100-24Q switches are hot-removable
and hot-insertable field-replaceable units (FRUs): You can remove and replace them
without powering off the switch or disrupting switch functions.
Before you begin removing an expansion 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 142 ).
