Removing a Fan Tray from a QFX3600 or QFX3600-I Device
The fan trays in QFX3600 and QFX3600-I devices are hot-removable and hot-insertable field-replaceable
units (FRUs): you can remove and replace them without powering off the device or disrupting device
functions.
Before you remove a fan tray from a QFX3600 or QFX3600-I device, ensure that you have taken the
necessary precautions to prevent electrostatic discharge (ESD) damage (see “Prevention of Electrostatic
Discharge Damage” on page 242).
Ensure that you have the following parts and tools available to remove a fan tray from a QFX3600 or
QFX3600-I device:
•
ESD grounding strap
•
An antistatic bag or an antistatic mat
CAUTION: Replace a failed fan tray with a new fan tray within 1 minute of removal
to prevent chassis overheating.
To remove a fan tray from a QFX3600 or QFX3600-I device (see Figure 158 on page 450):
1. Place the antistatic bag or the antistatic mat on a flat, stable surface.
2. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the
chassis.
WARNING: To avoid injury, do not touch the fan with your hands or any tools as
you slide the fan tray out of the chassis—the fan may still be running.
3. Grasp the handle on the fan tray and pull firmly to slide the fan tray halfway out of the chassis.
