Maintaining QFX10002 Cooling System Components
Use the following procedures to replace a fan module in a QFX10002:
Removing a Fan Module from a QFX10002
Before you remove a fan module from a QFX10002, ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see Prevention of Electrostatic Discharge Damage).
Ensure that you have the following parts and tools available to remove a fan module from a QFX10002:
ESD grounding strap
Antistatic bag or an antistatic mat
The fan modules in QFX10002 models 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.
Replace a failed fan module with a new fan module within one minute of removal to prevent chassis overheating. Before removing the fan module, ensure you have a replacement fan module at hand.
To remove a fan module from a QFX10002 switch (see Figure 1):
When a fan module is removed, the CLI message Fan/Blower is Absent is logged in the system log, and the system raises a minor alarm.
