Purpose

Use this MOP when installing a replacement/spare SBC 7000 chassis that does not include the AC Adapter Trays for the 451-01043 Tectrol AC power supplies. This MOP explains how to safely remove the 451-01043 Tectrol AC power supplies as well as the AC Inlet modules from one chassis and install them into a new chassis.

Important Safety Information






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

Shut down the chassis gracefully prior to performing this procedure to ensure the SSD drives aren't corrupted. See Appendix A for details.

Procedure

Use the following procedure to safely remove the 451-01043 Tectrol AC power supplies as well as the AC Inlet modules from one chassis and install them into a new chassis:

  1. Shut down the system gracefully from the BMC GUI or HOST processor. See Appendix A (and if necessary, Appendix B) for details. Ensure the lights on the back of the chassis appear are as shown in the following figure.


  2. Unplug both power supplies and wait for all of the LEDs to power off.


  3. Remove both AC power supplies by pulling the latch to the left and then pulling straight out.


  4. Remove the retaining screw from both AC Inlets.


  5. Remove the AC Inlets by sliding it to the right by 1/2” to grasp it, and pull straight back to remove.




  6. Replace the retaining screws in the chassis that you are returning as it may be required later.


  7. On the new chassis, remove the retaining screws, if they came installed on the new chassis.


  8. On the new chassis, insert each AC inlet by aligning it with the left side of the power supply slot.


  9. Slide each AC inlet while pushing against the left side of the power supply slot until it is fully seated.


  10. Secure each AC inlet by installing the screws removed from the chassis in step 7.  If the screws were not shipped on the replacement chassis, reuse the screws from the chassis you are returning.


  11. Install both AC Power supplies by sliding them in. Plug in the power cord.

Appendix A: 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 B 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 B: 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 BMC IP address is unknown and there is a serial connection to the BMC module, log in to the BMC Console using the login credentials.

    Log into BMC Console
    BMC00106B03CB0C login: root
    Password: 
    Executing [-/bin/sh]
    
    BusyBox v1.13.2 (2014-05-23 07:42:17 EDT) built-in shell (ash)
    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 
    eth0      Link encap:Ethernet  HWaddr 00:10:6B:03:CB:0C  
              inet addr:10.x.xx.xxx  Bcast:10.x.xx.xx  Mask:255.255.255.0

              TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

              RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
              Interrupt:2


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

  3. 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

                            Please note that this maintenance shell is only intended for use by
                            Authorized,qualified personnel for maintenance purposes.
                            If you are not a A,Q personnel, STOP.
                            You risk making the card non-functional by attempting any operations using
                            this shell.
    --------------------------------------------------------------------------------------
    Enter Maintenance Mode?(y/n):n
    
    
  4. Once the host processor starts up, log in and then type init 0 to shut down the host processor.

    Enter 'init 0' to shut down Host processor
