  3. Set the module aside in a safe place.

Step 7: Remove chassis

You must remove the existing chassis from the equipment rack or system cabinet before you can install the replacement chassis.

  1. Remove the screws from the chassis mount points.

    Note If the system is in a system cabinet, you might need to remove the rear tie-down bracket.
  2. With the help of two or three people, slide the impaired chassis off the rack rails in a system cabinet or L brackets in an equipment rack, and then set it aside.

  3. If you are not already grounded, properly ground yourself.

  4. Using two or three people, install the replacement chassis into the equipment rack or system cabinet by guiding the chassis onto the rack rails in a system cabinet or L brackets in an equipment rack.

  5. Slide the chassis all the way into the equipment rack or system cabinet.

  6. Secure the front of the chassis to the equipment rack or system cabinet, using the screws you removed from the impaired chassis.
