Removing and installing a power supply for an EDR1 PCIe storage enclosure

Use the following precautions whenever you handle electronic components or cables:

• Attach a wrist strap to an unpainted metal surface of your hardware to prevent electrostatic discharge (ESD) from damaging your hardware.
• If you do not have a wrist strap, before 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.
• Keep all electronic components in the shipping container or envelope until you are ready to install them.
• If you remove and reinstall an electronic component, temporarily place the component on an ESD pad or blanket, if available.

To remove and install a power supply, complete the following steps:

1. Use the service indicator light-emitting diodes (LEDs) to help identify the part. For instructions, see Identifying a part.
2. Determine whether the repair can continue concurrently. To continue the repair concurrently, the second power supply LEDs must be set as follows:
   • The ac power LED (green) is on solid.
   • The dc power LED (green) is on solid.
   • The fault LED (amber) is off.

3. If any of these conditions are not true, begin with The power supply will be serviced nonconcurrently. Otherwise, continue with The power supply will be serviced concurrently.

   • The power supply will be serviced concurrently.

     Do not remove power from the working power supply during this procedure. Remove the cable tie that secures the power cable to the cable management bracket. Remove the power cable from the power supply to be removed. Go to step 4.

   • The power supply will be serviced nonconcurrently.

     Power off the system or systems that are using the PCIe storage enclosure. Remove the cable tie that secures the power cable to the cable management bracket. Remove the power cables from both the power supplies. Go to step 4.

4. Remove the power supply:
   1. While pressing the terra-cotta release tab to the left, grasp the handle and gently slide the power supply partially out of the slot.
   2. Pull the power supply out from the slot, making sure that you support the bottom of the power supply.

5. Install the power supply:
   1. Gently slide the power supply into the enclosure until the terra-cotta release tab latches.
   2. Reconnect the power cable to the power supply. Secure the power cable to the cable management bracket by using a cable tie.
      Notes:

      • If this service action was a concurrent repair, the vital product data of the power supply will not be updated until the next time the system or partition is powered off and then powered on.
      • If this service action was a nonconcurrent repair, reconnect the power cable to the other power supply, secure the power cable to the cable management bracket by using a cable tie, and power on the system or systems.
      • Ensure that the ac and dc power (green) LEDs are lit and that the fault (amber) LED is off.
