    Removing the Fan Tray

    The fan tray is a hot-removable and hot-insertable field-replaceable unit (FRU); you can remove and replace the fan tray while the Junos Pulse Gateway is running without turning off power to the Junos Pulse Gateway.

    Caution: Do not remove the fan tray unless you have a replacement fan tray available.

    Ensure that you have the following parts and tools available to remove a fan tray from the Junos Pulse Gateway chassis:

    • Electrostatic discharge (ESD) grounding strap
    • Replacement fan tray
    • An antistatic bag or an antistatic mat

    Caution: The fan tray can be removed and replaced while the Junos Pulse Gateway is operating. However, the fan tray must be replaced within 30 seconds of removing the fan tray to prevent overheating of the chassis.

    To remove a fan tray from the Junos Pulse Gateway chassis:

    1. Place the antistatic bag or the antistatic mat on a flat, stable surface.
    2. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
    3. Squeeze both handles of the fan tray to release the latches that lock the fan tray in the chassis.

      Warning: To avoid injury, do not touch the fans with your hands or any tools as you slide the fan tray out of the chassis—the fans might still be spinning.

    4. Grasp the handles on the fan tray and pull firmly to slide the fan tray halfway out of the chassis.
    5. When the fan stops 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.
