    Removing a Fan Tray from an EX9208 Switch

    An EX9208 switch has a single, field-replaceable 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 switch is running without turning off power to the switch or disrupting switching functions.

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

    The fan tray is installed vertically on the left side on the rear of the chassis.

    Before you remove a fan tray:

    Ensure that you have the following parts and tools available to remove a fan tray from an EX9208 switch chassis:

    • Electrostatic discharge (ESD) grounding strap
    • Phillips (+) screwdriver, number 1 and 2
    • Replacement fan tray

    To remove a fan tray from an EX9208 switch chassis (see Figure 1):

    1. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
    2. Loosen the captive screws on the fan tray faceplate using a screwdriver.
    3. Grasp the fan tray handle, and pull it out approximately 1 to 3 inches
    4. Press the latch located on the inside of the fan tray to release it from the chassis.
    5. Place one hand under the fan tray to support it, and pull the fan tray completely out of the chassis.
