Removing a JCS1200 Fan Module
Figure 1 shows how to remove and install a fan module.
Figure 1: Removing and Installing a JCS1200 Fan Module

![]() | Note: While the JCS1200 platform is operating, only one fan module should be removed at a time. Removing two fan modules might cause the JCS1200 platform to overheat. |
To remove a fan module (see Figure 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.
- Remove the shipping block that is installed
below the release levers:
Figure 2: Removing the Shipping Block


Note: When the JCS1200 platform is shipped, each fan module has a shipping block installed below the release lever that is on the same side as the fan module orientation mark.
- Remove the Phillips screw that attaches the shipping block to the platform.
- Pull the shipping block away from the platform. Place the shipping block and screw in a safe place.
- Press down on the release levers on either side of the fan module you are removing. The module moves out of the bay approximately 0.25 in. (0.6 cm).
- Pull the fan module out of the bay.

To install a fan module (see Figure 3):
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Orient the fan module to the selected fan
module bay.
Figure 4: Fan Module Orientation Marks

- If you are installing a fan module in fan module bay 1 or 2, orient the fan so the orientation mark is at the bottom-right corner.
- If you are installing a fan module in fan module bay 3 or 4, orient the fan so the orientation mark is at the top-left corner.
- Slide the fan module into the bay until it stops.

Note: Make sure the release levers for the fan module return to a locked position.
- If you are shipping the JCS1200 platform to
another location, install the shipping block that came with the platform.

Note: When the JCS1200 platform is shipped, a shipping block must be installed for each fan module. The shipping block is installed below the release lever that is on the same side as the fan module orientation mark.
Figure 5: Installing the JCS1200 Shipping Block

- Orient the shipping block below the release lever on the same side as the orientation mark on the fan module.
- Push the shipping block into the slot below the release lever.
- Install the Phillips screw that attaches the shipping block to the platform.
