About maintaining the platform

The i2000/i4000 Series platform contains components that you can replace individually without exchanging the entire system. This platform contains these replaceable components:

  • AC power supply

About AC power supplies

This platform can support up to two AC power supplies. Most platforms come with only one power supply by default. 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.

The 250W AC power supply

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, 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 unplug AC power from any unused power supplies.
CAUTION:
Do not mix power supply models. If two power supplies are installed in the same system, use only power supplies of the same model.
CAUTION:
As a safety precaution, the socket outlet must be installed near the equipment and be easily accessible.
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.

Replacing a 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.
  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 power supply from your system, disconnect the AC power cord from the power supply by squeezing one or both of the power cord lock actuators.
    Important: Locking AC power cords might not be available in all countries.
  3. Remove the failed AC power supply by squeezing the ejector latch and pulling straight toward you.
    Note: After you remove a power supply from the system, wait for 30 seconds before reinserting the supply to ensure that the circuitry is fully discharged.
  4. Inspect the new power supply, especially the connector area, for any damage that might have occurred during shipment.
  5. Slide the new power supply into the empty slot and push it in until the latch engages.
    Note: Use care to ensure that the connector on the power supply does not contact any of the hardware that is protruding on the back of the chassis.
  6. Ensure that the power supply is fully seated in the chassis.
  7. Connect the AC power cord to the new power supply.
    If the system does not boot after you apply power to the power supply, use the touchscreen LCD to power on the system.
Performing a power supply replacement might cause alert messages on the LCD screen. Use the LCD touchscreen to clear any power supply alert messages, if needed.

Replacing a power supply in a dual-supply system

In the event of a power supply failure, you can replace an AC power supply in a dual-supply system without powering down the system, provided that there is at least one power supply operating during the replacement process.
CAUTION:
Be sure that you are using the correct wattage power supply when performing a power supply replacement.
  1. Make sure that you have a live power supply already installed in your system if you want to hot swap a power supply while the system is running.
  2. Before removing the power supply from your system, disconnect the AC power cord from the power supply by squeezing one or both of the power cord lock actuators.
    Important: Locking AC power cords might not be available in all countries.
  3. Remove the failed AC power supply by squeezing the ejector latch and pulling straight toward you.
    Note: After you remove a power supply from the system, wait for 30 seconds before reinserting the supply to ensure that the circuitry is fully discharged.
  4. Inspect the new power supply, especially the connector area, for any damage that might have occurred during shipment.
  5. Slide the new power supply into the empty slot and push it in until the latch engages.
    Note: Use care to ensure that the connector on the power supply does not contact any of the hardware that is protruding on the back of the chassis.
  6. Ensure that the power supply is fully seated in the chassis.
  7. Connect the AC power cord to the new power supply.
    If the system does not boot after you apply power to the power supply, use the touchscreen LCD to power on the system.
Performing a power supply replacement might cause alert messages on the LCD screen. Use the LCD touchscreen to clear any power supply alert messages, if needed.
