Install the model 9116-561 and 570 system processor assembly

You might need to install the system processor assembly. Use the procedure in this section to perform this task.

1. Remove the existing system processor assembly or filler. Refer to Remove the model 9116-561 and 570 system processor assembly.
   Attention:

   • Attach a wrist strap to an unpainted metal surface of your hardware to prevent electrostatic discharge from damaging your hardware.
   • When using a wrist strap, follow all electrical safety procedures. A wrist strap is for static control. It does not increase or decrease your risk of receiving electric shock when using or working on electrical equipment.
   • If you do not have a wrist strap, just prior to removing the product from ESD packaging and installing or replacing hardware, touch an unpainted metal surface of the system for a minimum of 5 seconds.
   If necessary, remove the new system processor assembly from its antistatic package.
2. Install any dual inline memory modules (DIMMs) in the new system processor assembly. Refer to Install model 9116-561 or 570 memory modules.
3. Place the system processor assembly A into the system backplane assembly, and then lock it into place with the locking arms B as shown. Press the locking knobs C into the locked position.
