Installing an 8203-E4A, 8204-E8A, 9407-M15, 9408-M25, or 9409-M50 power supply with power on

Learn how to install a second power supply while the system power is on.

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

To install a power supply in a system that is not managed by an HMC while the system power is on, complete the following steps.
Important: You must have a functioning power supply in the system to complete these steps.
  1. Complete the prerequisite tasks described in Before you begin.
  2. Attach the wrist strap.
    Attention:
    • Attach a wrist strap to an unpainted metal surface of your hardware to prevent electrostatic discharge (ESD) 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.
  3. Remove the front cover, as described in Removing the front cover from a rack-mounted model or Removing the front cover from a stand-alone model.
  4. Remove the power supply filler by grasping the filler and pulling it out of the system.
  5. Pull the power cable out of the slot. The power cable might be secured under the plate at the top of the power supply slot. If so, release the plate by completing the following steps:
    1. Release the plate by squeezing the two tabs on the top of the power supply slot.
    2. Remove the cable and pull it gently forward.
    3. Lift the plate back up and squeeze the two tabs until the plate is secure.
  6. Push the power supply (A) into place until the locking latch snaps into place as shown in Figure 1.
    Note: Ensure that the power cable does not become pinched while installing the power supply.

  7. Connect the power cable (B) to the front of the power supply.
  8. Replace the front cover, as described in Installing the front cover on a rack-mounted model or Installing the front cover on a stand-alone model.
  9. Close the front rack door.
