Replace a high voltage DC power supply

You can upgrade your AC-powered or standard DC-powered system with high voltage DC (HVDC) power supply units (PSUs). In this case, you must install two HVDC PSUs, even if your system previously included only one PSU. You can also replace failed HVDC PSUs with replacement HVDC PSUs.
For a dual-supply system, you can perform the replacement without powering down the system, provided that there is at least one PSU operating during the replacement process.
Be sure that you are using the correct wattage and part number (PWR-0378-xx) of power supply unit (PSU) in all bays, as applicable, when performing a power supply replacement.
All photos shown are examples. The appearance of your power supply units might vary slightly, but be sure to use the pull handle orientation and perforations in the power cord face to verify the correct PSU for your platform.
  1. Be sure that the circuit breaker for the DC mains power source is switched off.
  2. Remove the failed HVDC PSU by squeezing the ejector latch and pulling straight toward you.
    After you remove a power supply unit (PSU) from the system, wait at least 30 seconds before you reinstall the PSU. If you apply power sooner, the supply might need to remain unpowered or removed from the system for several minutes to allow it to fully discharge internally before you should try to reinstall it.
  3. If an output connector protective cap is installed on your new PSU, remove it before installing the PSU into your system.
  4. Inspect the new PSU, especially the connector area and pins, for any damage that might have occurred during shipment.
  5. Slide the new PSU into the empty slot, and push it in until the ejector latch engages and clicks.
    While installing the supply, use care to ensure that the supply's connector does not come into contact with the rear of the chassis.
  6. Insert the auto locking HVDC power cord into the PSU input connector and press firmly until it is fully seated.
    Be sure to route the power cords away from the fan tray so that the cords do not impede access to it.
  7. Ensure that the PSU is fully seated in the chassis by making sure it does not come out when gently pulled.
  8. Connect the three ring terminals on the end of the cord to an approved power source.
    The blue wire (-L) connects to the negative terminal of an approved source, the brown wire (+N) connects to the positive terminal of an approved source, and the yellow/green wire connects to earth/ground.
  9. Reapply input power from DC mains power source by switching the circuit breaker back on.
    If the system is fully powered down and does not boot after you apply power to the PSU, use the touchscreen LCD to power on the system.
  10. Use the LCD touchscreen to clear any alert messages that might have resulted from performing the PSU replacement.
