Recycling the PCB Assembly (PCBA)

This chapter contains the following topic:

Recycling the PCB Assembly (PCBA)

The PCBA is secured to the bottom of the server chassis. To recycle the PCBA, you will need to remove some components from the server. The assemblies and subassemblies are secured to the chassis and held together by M3x0.5mm screws.

Before you begin


Note

For Recyclers Only! This procedure is not a standard field-service option. This procedure is for recyclers who will be reclaiming the electronics for proper disposal to comply with local eco design and e-waste regulations.

To remove the printed circuit board assembly (PCBA), the following requirements must be met:

Procedure

Step 1

Remove the mouting screws from the left and right exterior sides of the chassis.

The following figure shows these screws.

Step 2

Remove the SSD backplane cables.

  1. Using a screwdriver, rotate each of the top rear cover screws counter-clockwise until it disengages.

  2. Remove the top rear cover.

    The following image shows the location of the rear top cover screws.

  3. Reach down to grasp the SSD backplane cable connectors, then disconnect the cables from the SSD backplane and Midplane assembly.

  4. Cut the cable tie that secures the SSD backplane cables to the chassis.

Step 3

Remove the cover plate.

  1. Open the fan compartment doors by pushing the latches inward toward each other.

  2. Using a screwdriver, rotate each of the Midplane assembly screws counter-clockwise until it disengages.

  3. Grasp the cover and remove it by hand.

    The following illustration shows the location of the screws.

Step 4

Remove the Midplane PCBA.

  1. Remove all the fans (if present).

  2. Remove the fan cage.

  3. Disconnect the sensor connector from the motherboard.

  4. Locate the cable tie on the interior chassis wall and cut the tie so that the cables are no longer attached to the chassis.

  5. Lift the Midplane assembly straight up to disconnect it from its sockets and remove it from the chassis.

The following image shows the locations of these components.

Step 5

Disassemble the Midplane PCBA.

  1. Using a standard screwdriver, gently pry up the Bus Bar modules at each connector until you can remove them by hand.

  2. Using a screwdriver, rotate each of the screws counter-clockwise until it disengages.

  3. Grasp the midplane bracket and remove it by hand.

  4. Separate the Midplane PCBA from the midplane bracket by hand.

    The following image shows the screws and components.

Step 6

Remove the drive cage mounting screws from the front of the chassis.

The following illustration shows these screws.

Step 7

Open the double doors for the drive cage.
Step 8

Remove the drive cage.

  1. Disconnect the motherboard sensor connector from the motherboard by hand.

  2. Using a long standard screwdriver, disconnect the ribbon cable from the each of the FPC motherboard connectors by swiping the connector towards the chassis front panel.

    Note 

    The FPC connectors have small hinges that open by pivoting toward the chassis front panel. When a connector opens, its ribbon cable is disconnected. The ribbon cable is attached to the inside of the drive cage, which can add resistance when you remove the drive cage.

  3. Using a screwdriver, rotate each of the screws counter-clockwise until it disengages.

  4. Lift the drive cage out of the chassis.

    If the ribbon cables for the FPC connectors cause resistance when you lift the drive cage, pull the cables to detach them from the drive cage.

    The following image shows the screws and components.

Step 9

Remove the mounting screws for the motherboard and lift the motherboard out of the chassis.

The following image shows the location of the screws.

Step 10

Dispose of the motherboard, PCBA, and all other removed components properly.
