Platform Maintenance

Platform maintenance

The
r5000/r10000 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
  • Fan tray (r10000 Series only)
  • Storage drive (r10000 Series only)

Power supply unit (PSU) replacement overview

F5 platforms support up to two AC
, DC,
or high-voltage DC (HVDC)
hot-swappable power supply units (PSUs).
Some platforms come with only one PSU by default.
This platform includes two PSUs by default.
Running without power supply units (PSUs) installed in all available bays in the platform can affect cooling and electromagnetic interference (EMI). If you need to run the unit with one PSU, you must install a PSU blank into the empty PSU bay. The PSU blank is required to maintain proper airflow in the system. If you do not have a PSU blank, leave all supplies installed and disconnect power from any unused supplies.
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.
You should use only one power supply unit (PSU) type (AC
, DC,
or HVDC) in a platform. AC/
DC/
HVDC interoperability is not supported.
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.
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.
The power supply units (PSUs) do not have an on/off switch. Power is controlled from the rack switch
or the mains power source
.
After removing input power from any power supply unit (PSU), wait 30 seconds before reapplying input power to the PSU.

AC power supply units (PSUs)

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 PSU redundancy, which ensures that the system is unaffected if a single supply fails in a system with more than one operational supply installed.
When you add or replace a supply 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 650W PSU, you can find the part number on the top of the supply. For 650W AC, the part number is PWR-0306-xx, and for 650W DC, it is PWR-0307-xx. These supplies have a black vertical pull handle and a silver-colored power cord face with rectangle-shaped perforations.

As a safety precaution, the socket outlet must be installed near the equipment and be easily accessible.
You should use only one power supply unit (PSU) type (AC
, DC,
or HVDC) in a platform. AC/
DC/
HVDC interoperability is not supported.

Replace an AC power supply unit

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.
Be sure that you are using the correct wattage and part number (
PWR-0306-xx
PWR-0388-xx
) of power supply unit (PSU) in all bays, as applicable, when performing a PSU replacement.
All photos shown are examples. The appearance of your power supply units (PSUs) 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, 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 (input connector) from the PSU by pulling one or both of the power cord locking tabs away from the supply.
    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.
    After you remove a power supply unit (PSU) from the system, wait at least 30 seconds before you reinstall the PSU. Allow the PSU to fully discharge before you reinstall it.
  4. If an output 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 and pins, 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.
    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. Insert the auto locking AC 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.
  9. Connect the power cord to the power source.
    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.

HVDC power supply units (PSUs)

This platform can support up to two high-voltage DC (HVDC) power supply units (PSUs). You can hot swap PSUs 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 supply fails in a system with more than one operational supply installed.

Replace a high-voltage DC (HVDC) power supply unit

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-0384-xx) of power supply unit (PSU) in all bays, as applicable, when performing a PSU replacement.
All photos shown are examples. The appearance of your power supply units (PSUs) 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, 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. Be sure that the circuit breaker for the HVDC mains power source is switched off.
  3. 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. Allow the PSU to fully discharge before you reinstall it.
  4. If an output 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 and pins, 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.
    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. 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.
  8. Ensure that the PSU is fully seated in the chassis by making sure it does not come out when gently pulled.
  9. Connect the three ring terminals on the end of the cord to an approved power source.
    The -L wire connects to the negative terminal of an approved source, the +N wire connects to the positive terminal of an approved source, and the ground wire connects to Earth/Ground.
  10. Reapply input power from HVDC 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.
  11. Use the LCD touchscreen to clear any alert messages that might have resulted from performing the PSU replacement.

You should use only one power supply unit (PSU) type (AC
, DC,
or HVDC) in a platform. AC/
DC/
HVDC interoperability is not supported.
The platform must be installed in a RESTRICTED ACCESS LOCATION, such as a central office or customer premises environment.
Copper cables used for grounding must meet appropriate safety standards.
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.
The platform must be grounded to a common bonding network (CBN).
The battery return terminals on the platform are in an isolated DC return (DC-I) configuration.
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.
After removing input power from any power supply unit (PSU), wait 30 seconds before reapplying input power to the PSU.

Replace a standard 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 Phillips 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.
Be sure that you are using the correct wattage and part number (PWR-0385-xx) of power supply unit (PSU) in all bays, as applicable, when performing a PSU replacement.

Fan tray replacement overview

The fans in F5 platforms help maintain airflow throughout the chassis and run constantly while the unit is powered on. Over time, the fans can wear out, requiring you to replace the fan tray. For platforms that have a removable fan tray, you can change or replace the fan tray as part of the routine maintenance of the unit, or in the event of a fan failure.
Fan tray
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.

Replace the fan tray

To ensure that you can easily access the fan tray, route the power cords away from the fan tray so that the cords do not drape over or cross in front of it.
You do not need special tools and do not need to power down the unit when replacing the fan tray.
Operating the unit without a fan tray for more than 30 seconds might result in performance throttling or a thermal shutdown of the unit.
  1. Locate the fan tray on the back of the chassis.
  2. Loosen the fan tray screws by turning them counterclockwise with a Phillips screwdriver.
    The screws that hold the fan tray in place are captive and cannot be removed from the assembly.
  3. Remove the fan tray from the chassis by grasping the handles and pulling straight toward you.
  4. Slide the new fan tray into the fan tray slot.
  5. Tighten the screws into place with a Phillips screwdriver.
    Use 5 inch-pounds (0.6 Newton-meters) of torque on these screws. The fan tray is connected to the system when you tighten the screws completely. Once seated, the fan tray automatically powers up and begins circulating air through the chassis.

Storage drive replacement overview

F5 r10000 Series platforms include two solid-state drives (SSDs) that are configured with RAID enabled. In the event of a drive failure, F5 sends you a new replacement drive for the faulty drive. For these platforms you do not need to power down the system when replacing a drive as part of routine maintenance or in the event of a drive failure.
Replacement drives provided by F5 do not come pre-installed with software.
Storage drive location
When performing a storage drive replacement, you must remove the failed drive from the software RAID array before physically removing the drive from the chassis.

Remove a faulty drive from the RAID array

Before you remove a faulty storage drive from your system, you should identify the faulty drive and remove it from the RAID array.
  1. Connect to the system using a management console or console server.
    The default baud rate and serial port configuration is 19200/8-N-1.
  2. Log in to the command line interface (CLI) of the system using an account with admin access.
    When you log in to the system, you are in user (operational) mode.
  3. Show the current status of the drives.
    show system raid raid-array-status
    A summary similar to this example displays:
    appliance-1# show system raid raid-array-status ARRAY ARRAY NAME BAYID SERIAL NUMBER MEMBER STATUS SIZE ---------------------------------------------------------- ssd1 0 PHLJ912345PK1P0FGN true ok 684.7G ssd2 1 PHLJ912345Q61P0FGN true undefined 684.7G
    The RAID array includes both storage drives as members. Note the serial number for the faulty drive and in which bay it is installed.
  4. Change to config mode.
