Purpose

Use the following procedure to remove the 451-01043 Tectrol AC power supplies and AC inlet modules from an SBC 7000 chassis, and replace them with the new 451-01060 ABB-GE or GE AC power supplies and adapter trays.






Warning

Due to the size and weight of the SBC 7000 chassis, at least two people are required when lifting, mounting or unmounting the chassis.


To prevent damage from electrostatic discharge, an ESD strap is provided in the SBC chassis accessory kit. Refer to the page "Connecting Electrostatic Discharge Wrist Strap on SBC 7000" in the SBC Core Hardware Guide to install the wrist strap.

Prerequisites

  • Ensure the BMC firmware version is 3.24 or higher. If both AC supplies are failed, you can install the new supplies with the CSC100 removed to update the BMC firmware. After the update, once the CSC100 is reinstalled, you must perform the BMC firmware update to update the BIOS on the CSC100.
  • You must replace both the power supplies. The system is not intended to operate with a combination of Tectrol and GE power supplies.
  • Shut down the chassis gracefully before performing the procedure to prevent the SSD drive corruption. For more details, refer to Appendix B.

Procedure

  1. Check the BMC firmware version and update it if it is lower than 3.24. For more information, refer to Appendix A.
  2. Shut down the system gracefully from the BMC GUI or HOST processor. For more information, refer to Appendix BEnsure the LED indicator on the back panel appears as below:


  3. Unplug both power supplies and wait for all LED indicators to turn off.


  4. Pull the latch to the left-hand side and then pull straight out to remove both AC power supplies.

  5. Remove the retaining screw from both AC inlets.


  6. Remove the AC inlets by sliding them to the right for 0.5 inches to grasp them and pull straight back to remove them. Return the AC inlets when returning the old power supplies.




  7. Place the retaining screws on the chassis for future use.


  8. Integrate the new power supply and adapter tray as one unit. Insert the power supply into the open end of the tray to ensure the connectors are lined up correctly.


  9. Push the power supply into the tray and ensure it is inserted completely.




  10. Install the new power supply and adapter tray as a single unit.


  11. Push the unit gently with your thumb until the tray latch clicks.


  12. Ensure the installed unit is positioned as below:


  13. Connect the AC power supplies to the existing AC power cord using the supplied SAF-D-GRID TO IEC C20 cord adapter.


  14. Connect the C20 plug to the power cord from the original AC power cord.

Additional Instructions

  • You need to press your thumb on the latch/button on the top of the plug and then pull to remove the SAF-D-GRID plug.

  • Do not remove the tray when swapping the power supplies. Hold the power supply handle and then slide the power supply latch to the left-hand side using your thumb.

Appendix A - Checking and Updating BMC Firmware

Use the procedure below to check and update the BMC firmware.

  1. Obtain a valid BMC IP address. For more information, refer to Appendix C.
  2. Enter the BMC IP address and log on to the BMC GUI.
    Username: root
    Password: superuser
  3. Click Login.
  4. Check and update the BMC firmware. For more information, refer to Upgrading BMC Firmware.

Appendix B - Gracefully Shutting Down the Host CPU from the BMC GUI

Use the procedure below to shut down the system gracefully from the BMC GUI or HOST processor.

  1. Connect to the BMC GUI using the BMC IP address. Enter the credentials and click Login. See Appendix C to obtain the BMC IP address.


  2. On the BMC GUI, click the Remote Control tab and then click Server Power Control.


  3. Select Power Off Server and then click Perform Action.


Appendix C - Determining the BMC IP Address from the BMC Serial Port

Use the following steps to determine the BMC IP address from the BMC serial port.

  1. If the IP address is unknown and there is a serial connection to the BMC module, log in to the BMC Console.

    Log in to BMC Console

    Enter 'help' for a list of built-in commands.
    
    
  2. Enter ifconfig to find the BMC ip-address to use for the GUI.

    Enter ifconfig
    # ifconfig

    You can also enter solssh to connect directly to the host processor and  perform the shut down.

    Type "n" when prompted to enter maintenance mode.

    Enter solssh
    #  solssh
    -/bin/sh: solssh: not found
    # /usr/local/bin/solssh
    Hit <Enter><Esc>t to exit solssh
