Removing a Processor
- Only Huawei technical support or personnel authorized by Huawei can remove the processors from Huawei servers.
- Do not wear ESD gloves during processor replacement. The gloves may catch on pins on the processor socket and damage it.
Procedure
- Power off the server.
For details, see Power-Off Procedure.
- Remove the power cables from the PSUs.
For details, see Removing PSU Cables.
- Remove the server.
For details, see Removing the Server.
- Place the server on the ESD workstation.
- Remove the chassis cover.
For details, see Removing the Chassis Cover.
- Remove the air duct or built-in drive module.
For details, see Removing the Air Duct or Removing the Built-in Drive Module.
- Determine the position of the processor.Figure 8-89 Positions of processors
- Remove the heat sink.
- Use a Phillips screwdriver to loosen the four screws (marked 2 in the label) in the middle of the heat sink in a diagonal sequence. See (1) in Figure 8-90.
- Use a Phillips screwdriver to loosen the two diagonal screws (marked 1 in the label) on the heat sink. See (2) in Figure 8-90.
- Lift the heat sink and place it upside down on the ESD desk.
- Remove the processor carrier and processor.
- Insert a flat-head screwdriver into the groove of the processor carrier, and twist it to pry up one side of the carrier. See (1) in Figure 8-91.
Insert only the tip of the flat-head screwdriver. Do not apply excessive force.
- Holding the other end of the carrier, remove the carrier and processor in the arrow direction. See (2) and (3) in Figure 8-91.
- Insert a flat-head screwdriver into the groove of the processor carrier, and twist it to pry up one side of the carrier. See (1) in Figure 8-91.
- Remove the processor.
- When removing a processor, hold the processor and its carrier to prevent the processor from falling off.
- To prevent damage to the pins, do not touch the pins of the processor socket or the corresponding area on the processor.
- Keep the processor away from the chassis to prevent thermal compound from falling off.
- Bend the edge of the carrier with the triangular hole to release the processor from the carrier.Figure 8-92 Removing a processor (1)
- Hold the two sides of the processor and lift it.
Figure 8-93 Removing a processor (2) - Place the removed component in an ESD bag.
Clean the removed processor and put it into an ESD bag.
- Install a processor socket cover.
- Perform this operation only when a processor is not installed immediately.
- The processor socket cannot be exposed and must be covered by a processor or cover during transportation and storage.
- Aligning the processor socket cover with the guide pin on the processor socket, place the cover on the processor socket. See (1) in Figure 8-94.
- Press the positions shown by (2) in Figure 8-94 until you hear a click.
