About maintaining the platform

The i800 Series platform contains components that you can replace individually without exchanging the entire system. This platform contains these replaceable components:

  • AC power supply

About power supplies

This platform supports up to two AC hot swappable power supplies. Most platforms come with only one power supply by default.

CAUTION:
Running without power supplies installed in all available bays in the platform can affect cooling and electromagnetic interference (EMI). If you need to run the unit with one power supply unit (PSU), you must install a blank supply bracket into the empty power supply bay. The blank supply bracket is required to maintain proper airflow in the system. If you do not have a blank supply bracket, leave all supplies installed and disconnect power from any unused PSUs.
CAUTION:
Do not mix power supply unit (PSU) models. If two PSUs are installed in the same system, use only PSUs of the same model.
Important: This product is sensitive to electrostatic discharge (ESD). F5® recommends that you use proper ESD grounding procedures and equipment when you install or maintain the unit.
Note: The AC power supply units (PSU) do not have an on/off switch. You can control the power from the rack switch .
Note: After removing input power from any power supply unit, wait 30 seconds before reapplying input power to the power supply unit.

About AC power supplies

This platform can support up to two AC power supplies. You can hot swap a power supply without powering down the system if there are two installed, and one remains installed and operational during the replacement process.

The platform supports power supply redundancy, which ensures that the system is unaffected if a single power supply fails in a system containing more than one power supply.

CAUTION:
As a safety precaution, the socket outlet must be installed near the equipment and be easily accessible.

Replace an AC power supply in a single-supply system

In the event of a power supply failure, you can replace an AC power supply in a single supply system.
CAUTION:
Be sure that you are using the correct wattage power supply when performing a power supply replacement.
Note: All photos shown are examples. The appearance of your components or accessories might vary slightly.
  1. Use the touchscreen LCD to halt and power off the system.
    Performing a proper shutdown procedure helps maintain system integrity.
  2. Before removing the PSU from your system, disconnect the AC power cord from the power supply by pulling one or both of the power cord locking tabs away from the power supply.
    Important: Locking AC power cords might not be available in all countries.
  3. Remove the failed AC PSU by squeezing the ejector latch and pulling straight toward you.
    Note: After you remove a power supply unit (PSU) from the system, ensure that the replacement PSU has been unpowered for 30 seconds to ensure that the PSU circuitry is fully discharged before inserting the replacement PSU into the system.
  4. If a connector protective cap is installed on your new PSU, remove it prior to installing the PSU into your system.
  5. Inspect the new PSU, especially the connector area, for any damage that might have occurred during shipment.
  6. Slide the new PSU into the empty slot, and push it in until the ejector latch engages and clicks.
    Note: While installing the supply, use care to ensure that the supply's connector does not come into contact with the rear of the chassis.
  7. Ensure that the PSU is fully seated in the chassis by making sure it does not come out when gently pulled.
  8. Connect an auto locking AC power cord to the power input panel on the new PSU.
    Note: Be sure to route the power cords away from the fan tray so that the cords do not impede access to it.
  9. Connect the power cord to the power source.
    If the system does not boot after you apply power to the PSU, use the touchscreen LCD to power on the system.
  10. Optional: Use the LCD touchscreen to clear any alert messages that might have resulted from performing the PSU replacement.

Replace an AC power supply in a dual-supply system

In the event of a power supply unit (PSU) failure, you can replace an AC PSU in a dual-supply system without powering down the system, provided that there is at least one PSU operating during the replacement process.
CAUTION:
Be sure that you are using the correct wattage power supply when performing a power supply replacement.
Note: All photos shown are examples. The appearance of your components or accessories might vary slightly.
  1. Make sure that you have a live power supply unit (PSU) already installed in your system if you want to hot swap a PSU while the system is running.
  2. Before removing the PSU from your system, disconnect the AC power cord from the power supply by pulling one or both of the power cord locking tabs away from the power supply.
    Important: Locking AC power cords might not be available in all countries.
  3. Remove the failed AC PSU by squeezing the ejector latch and pulling straight toward you.
    Note: After you remove a power supply unit (PSU) from the system, ensure that the replacement PSU has been unpowered for 30 seconds to ensure that the PSU circuitry is fully discharged before inserting the replacement PSU into the system.
  4. If a connector protective cap is installed on your new PSU, remove it prior to installing the PSU into your system.
  5. Inspect the new PSU, especially the connector area, for any damage that might have occurred during shipment.
  6. Slide the new PSU into the empty slot, and push it in until the ejector latch engages and clicks.
    Note: While installing the supply, use care to ensure that the supply's connector does not come into contact with the rear of the chassis.
  7. Ensure that the PSU is fully seated in the chassis by making sure it does not come out when gently pulled.
  8. Connect an auto locking AC power cord to the power input panel on the new PSU.
    Note: Be sure to route the power cords away from the fan tray so that the cords do not impede access to it.
  9. Connect the power cord to the power source.
    If the system does not boot after you apply power to the PSU, use the touchscreen LCD to power on the system.
  10. Optional: Use the LCD touchscreen to clear any alert messages that might have resulted from performing the PSU replacement.
