Removing a Fan Module from a QFX5200
Before you remove a fan module from a QFX5200, ensure that you have taken the necessary
precauons to prevent electrostac discharge (ESD) damage (see "Prevenon of Electrostac Discharge
Damage" on page 194).
Ensure that you have the following parts and tools available to remove a fan module from a QFX5200:
• ESD grounding strap
• Anstac bag or an anstac mat
The fan modules in QFX5200 are hot-removable and hot-insertable eld-replaceable units (FRUs): you
can remove and replace them without powering o the switch or disrupng switch funcons.
CAUTION: Replace a failed fan module with a new fan module within 1 minute of
removal to prevent chassis overheang. Before removing the fan module, ensure you
have a replacement fan module at hand.
To remove a fan module from a QFX5200-32C or a QFX5200-32C-L (see Figure 55 on page 128 and
Figure 56 on page 128):
1. Place the anstac bag or the anstac mat on a at, stable surface.
2. Aach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the
chassis.
3. Using a Phillips screwdriver, loosen the locking screw (3 or 4 turns).
4. On QFX5200-32C and QFX5200-32C-L models, grasp the handle on the fan module and squeeze
the outside of the handle to release the module. On QFX5200-48Y models, use a screwdriver to
loosen the capve screw with 3 or 4 turns.
