Removing a Fan Tray from a QFX3600 or QFX3600-I Device

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).

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

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.

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 1):

  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.
  4. When the fans stop spinning, slide the fan tray completely out of the chassis.
  5. Place the fan tray in the antistatic bag or on the antistatic mat placed on a flat, stable surface.

Note:

When a fan tray is removed, the CLI message Fan/Blower is Absent is logged in the system log, and the system raises a minor alarm.
