Removing a Fan Tray from a QFX3500 Device
The fan trays in QFX3500 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.
CAUTION:
Replace a failed fan tray with a new fan tray within 1 minute of removal
to prevent chassis overheating. Before removing the fan tray, ensure you have a
replacement fan tray.
Before you remove a fan tray from a QFX3500 device, ensure that you have taken the necessary precautions
to prevent electrostatic discharge (ESD) damage (see
“Prevention of Electrostatic Discharge Damage” on
).
Ensure that you have the following parts and tools available to remove a fan tray from a QFX3500 device:
•
ESD grounding strap
•
Antistatic bag or an antistatic mat
To remove a fan tray from a QFX3500 device (see
):
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.
3. Slide the locking lever toward the handle until it stops.
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 might still be running.
4. Grasp the handle on the fan tray and pull firmly to slide the fan tray halfway out of the chassis.
5. When the fans stop spinning, slide the fan tray completely out of the chassis.
6. Place the fan tray in the antistatic bag or on the antistatic mat placed on a flat, stable surface.
