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
  • DC power supply

About power supplies

The i2000/i4000 Series platform supports up to two AC or DC hot-swappable power supply units (PSUs). Most platforms come with only one power supply by default.

CAUTION:
Running without power supply units 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 of different wattage. If two PSUs are installed in the same system, use only PSUs of the same wattage and part number.
Important: You should use only one power supply unit (PSU) type (AC or DC) in a platform. AC and DC interoperability is not supported.
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: Be sure to use only the power supply unit (PSU) that is designed for your platform. For example, a lower wattage PSU might not electrically connect if your platform is designed to use a higher wattage PSU.
Note: The power supply units (PSUs) do not have an on/off switch. Power is controlled from the rack switch or the mains power source.
Note: After removing input power from any power supply unit (PSU), wait 30 seconds before reapplying input power to the PSU.

About AC power supplies

This platform can support up to two AC power supply units (PSUs). You can hot swap a 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 supply fails in a system containing more than one operational supply.

When you add or replace a power supply unit in your system, be sure to verify the supply's features and that the PWR-XXXX part numbers match to ensure that you have the correct supply.

On the 250W AC power supply unit, you can find the part number (PWR-0334-XX) on the top of the supply. This supply also has a horizontal pull handle and hexagon-shaped perforations in the power cord face.

Example of label to check PWR-XXXX part number

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

Replace an AC power supply

In the event of a power supply unit (PSU) failure, you can replace an AC PSU in your system. 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.
CAUTION:
Be sure that you are using the correct wattage and part number (PWR-XXXX) of power supply unit (PSU) in all bays, as applicable, when performing a power supply replacement.
Note: 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. Prepare the system for PSU replacement:
    • For a single-supply system, use the touchscreen LCD to halt and power off the system.
    • For a dual-supply system, make sure that you have an operational supply already installed in your system if you want to hot swap a supply while the system is running. If you do not want to hot swap, you can perform the replacement with the system powered off.
  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 the handle straight toward you.
    Note: After you remove a power supply unit (PSU) from the system, it should not be installed again until five or more seconds has passed. If you apply power sooner, the supply might need to remain unpowered and out of the system for several minutes to fully discharge internally before you should try to reinstall it.
  4. If a connector protective cap is installed on your new PSU, remove it before 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.
    Note: 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.

About DC power supplies

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

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

Important: Your platform must be running BIG-IP® software versions 12.1.1HF2, 12.1.2, or later to support DC power.

CAUTION:
Before installing a DC power supply unit (PSU), be sure that the circuit breaker for the DC mains power to the PSU is switched off.
CAUTION:
Before you begin to work with one of these platforms, refer to the DC-powered equipment environmental warnings for this platform and review any safety requirements for the facilities where the DC-powered platforms will be installed.
Important: You should use only one power supply unit (PSU) type (AC or DC) in a platform. AC and DC interoperability is not supported.
Important: The platform must be installed in a RESTRICTED ACCESS LOCATION, such as a central office or customer premises environment.
Note: Copper cables used for grounding must meet appropriate safety standards.
Note: Bare conductors should be coated with an appropriate antioxidant before being crimped. Make sure to clean all unplated connectors, braided strap, and bus bars to a bright finish prior to coating them with the antioxidant.
Note: The platform must be grounded to a common bonding network (CBN).
Note: The battery return terminals on the platform are in an isolated DC return (DC-I) configuration.
Note: When you are running a redundant DC power supply configuration, F5® strongly recommends that each DC power supply unit (PSU) in the system receives power from independent DC main power sources with independent circuit breakers.
Note: After removing input power from any power supply unit (PSU), wait 30 seconds before reapplying input power to the PSU.

Replace a DC power supply

Before you perform a DC power supply unit (PSU) replacement, you need to provide these tools and components:
  • 12 AWG copper cable long enough to reach from the platform to the DC power source
  • Flat-head or Philips head screwdriver
In the event of a power supply unit (PSU) failure, you can replace a DC PSU in your system. 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.
CAUTION:
Be sure that you are using the correct wattage and part number (PWR-XXXX) of power supply unit (PSU) in all bays, as applicable, when performing a power supply replacement.
