Remove the model 9116-561 or 570 power supply with power on

 

You might need to remove the power supply with the system power on to replace a failing power supply or as a part of another service action. Use the procedure in this section to accomplish this task.

Important: If the system or drawer you are removing the power supply from contains one of the following adapters in slot P1-C6/C7 you must remove the power supply with the power off to prevent system damage or data loss.
  • FC 1800 - HSL-2 Ports - 2 Copper
  • FC 1801 - HSL-2 Ports - 2 Optical
  • FC 1810 - GX Dual-port 4x HCA
Attention: Two power supplies must be present in the system to power on the system unit. If one power supply fails, or you have a system failure that does not stop the fans, the system will continue to operate. You can remove and replace the power supply with the system power on if it is done in less than 5 minutes. After 5 minutes, the system will power down to prevent the system from overheating. If the system power is off, go to Replace the model 9116-561 or 570 power supply with power off.

If your system is managed by the Hardware Management Console (HMC), you can use the HMC to complete the steps for removing a power supply. For instructions, see Remove a part using the Hardware Management Console.

To remove the power supply while the system power is on, complete the following steps:

  1. Perform the prerequisite tasks described in Before you begin.
  2. On a rack-mounted system unit, open the back rack door.
  3. Identify the power supply that needs to be replaced. For instructions, see Identify a failing part.
  4. Disconnect the power cable from the back of the power supply that you want to remove.
  5. As shown in Figure 1, pull the terra-cotta locking knob A into the open position.

  6. Lift the locking handle A (see Figure 2) into the open position, and then use the locking handle to pull the power supply out of the system B.

    Note: When you remove a power supply with the system power on, an error is logged. No action is required for this error.
