Note - This is a cold service procedure that must be performed by qualified service personnel. See Cold Service, Replaceable by Authorized Service Personnel for more information about this category of service procedures.

| Caution - The server must be fully shut down and the power cords disconnected.

| Caution - This procedure involves handling circuit boards that are extremely sensitive to static electricity. Ensure that you follow ESD preventative practices to avoid damaging the circuit boards.

| Caution - Components inside the chassis might be hot. Use caution when servicing components inside the chassis.

1. Remove the hard drive cage.

   See Remove the Hard Drive Cage.

2. Remove the three screws that secure the left or right light pipe assembly mounting plate to the hard drive cage.

   This step is identical for both left and right assemblies.

   The next steps depend on whether you are removing the right or left light pipe assembly.

   - For the right light pipe assembly, go to Step 3.

   - For the left light pipe assembly, go to Step 4

3. Remove the right light pipe assembly from its metal plate.

   This light pipe assembly is secured by two small hook-shaped clips that fit through holes in the metal plate and grip the other side of the plate. Two locator pins close to the front of the light pipe assembly help align the light pipes with the holes in the front panel flange.

   1. Use your thumb and index finger to grasp the light pipes near the two locator pins and gently bend the light pipes away from the mounting plate. Pull them just far enough to disengage the two hook-shaped clips from the slots.
   2. When the clips release their hold on the plate, remove the light pipe assembly from the metal plate.
4. Remove the left light pipe assembly from its metal plate.

   This light pipe assembly is secured by two small hook-shaped clips that fit through a pair of rectangular holes in the metal plate. These holes are to the left of a curved plastic spring. The hooks grip the plate through a corresponding pair of smaller holes to the right.

   Note - The curved plastic spring partially covers the hole used by the hook on the upper clip. This reduces access to the upper hook.

   1. Using the tip of a pointed object, such as the end of a paper clip or a stylus, push the hook end of the lower clip out of its hole. This is the hole that is not covered by the curved plastic spring.

      Tip - If possible, leave this pointed object in the lower hole to prevent the hook from sliding back in and use a different tool for the upper hook.

   2. Repeat Step a for the upper hook.
   3. When both clip hooks are out of their holes, slide the light pipe assembly toward the rear of the metal plate and remove it.
