    To remove the fan shuttle (see Figure 1):

    1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
    2. Power off any Routing Engines in the JCS1200 platform (see Powering Off a JCS1200 Routing Engine).
    3. If the platform is connected to a power source, disconnect the power from the platform and remove the power cables.
    4. Disconnect the cables from the modules in the rear of platform.
    5. Remove any of the following modules that are installed in the rear of the platform:
    6. Loosen the four captive thumb screws on the fan shuttle.
    7. Loosen the captive thumbscrews on the release handles, and pull the handles to the open position. The fan shuttle moves out of the chassis approximately 0.5 in. (1.3 cm).

      Caution: Use your hands to hold the frame of the fan shuttle where the fan module bays are located. Do not use the release handles to hold the fan shuttle.

    8. While you support the fan shuttle with your hands, pull the fan shuttle out of the JCS1200 chassis.

    Installing a JCS1200 Fan Shuttle

    Figure 2 shows how to remove and install a fan shuttle.

    To install the shuttle (see Figure 2):

    1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
    2. Make sure that no modules are installed in the fan shuttle and that the release handles on the shuttle are in the open position.

      Caution: Use your hands to hold the frame of the fan shuttle where the fan module bays are located. Do not use the release handles to hold the fan shuttle.

    3. Orient the fan shuttle so that fan module bays 1 and 3 are above fan module bays 2 and 4.
    4. Align the shuttle with the chassis, and push the shuttle into the chassis until it stops.
    5. Push the release handles to the closed position. The shuttle moves back fully into the chassis.
    6. Tighten the four captive thumbscrews on the fan shuttle.
    7. Tighten the captive thumbscrew on each release handle.

      Caution: The release handles have a safety switch that disables power output from the power boxes. If the release handles are not secured to the chassis with the thumbscrews, the platform will not power on.

    8. Install any of the following modules that you removed from the rear of the platform:
    9. Reconnect any cables that you disconnected from the modules in the rear of the platform.
    10. Reconnect the power to the platform (see Connecting the JCS1200 AC Platform to AC Power or Connecting the JCS1200 DC Platform to DC Power).
    11. Restart any Routing Engines that were powered off in the platform.
