CAUTION: The fan trays can be removed and replaced while the QFX3008-I
Interconnect device is operating. However, you must replace the fan tray
within 2 minutes of removing the fan tray to prevent overheating of the
chassis.

1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD
point on the chassis
2. Align the tray with the fan tray guide on the top of the tray. Slide in the fan tray until
it is fully seated in the chassis.
3. Turn the latch, located in the middle of the fan tray, clockwise to lock the fan tray in
the chassis.
4. Close the cover door and tighten the captive screws on the faceplate using your fingers.
