(20BW15.31 or later) Load From Cold

Prerequisites

Overview

The following procedure describes and illustrates the system software loading process commonly referred to as the Load From Cold (LFC). It is important to follow the steps listed below in order.

note: Performing this procedure will erase all scan data and image data. Obtain approval from customer before starting LFC.
note: USB Flash Drive can be inserted in any of the USB ports located on the console. Recommend using the Service USB port located next to the console's power switch.
note: These instructions and procedural flow are structured for performing a Load From Cold on a system with the same version software. In other words, a reload of the same software release. If the system being loaded is running an earlier release of software, refer to the Software Upgrade procedure in the Field Modification Instructions (FMI) for the appropriate software release. Additional instructions may be needed when upgrading software, and this information will only be found in the FMI instructions.

1 Software Deliverable

CT Operating System and Applications Software.

2 Pre-LFC Checks and Information Gathering

Procedure

  1. Confirm that a current System State Backup Media is on site. If unsure of the status of the System State, execute section Save System State (Approximately 5 minutes) to save a System State Backup to USB Flash Drive.

    • notice
    • When performing Save/Restore System State, check to ensure there is no two or more USB storage devices (SSA Key or other mobile storage devices) plugged in Console at the same time which may result in incorrect data storage.
  2. Remove USB Flash Drive from the host computer before starting the OS Load of the LFC process.

3 Information Capture

3.1 Common Information Capture

Procedure

  1. Record Autovoice Volume control settings (ALT-F3 by Toolchest, upper right corner).
  2. Write down all of the system INFO information on the reconfig screens, including the network information.
    Notice Image
    • notice
    • Failure to install the correct application software and select the correct system hardware (DAS, ORP, Gantry Sub) configuration will result in system downtime and DCB circuit board replacement. (This failure will occur after the flash download procedure flashes the firmware.)
  3. Verify and record specific system hardware configuration.
    1. Open a shell and type the following:

      {ctuser@hostname}cat /usr/g/config/INFO

    2. Record screen information.
  4. If the console has Connect Pro installed, write down the information when you run installhisris so it can be entered on the new console when installing the Connect Pro option.
  5. Close the Service Desktop window in the upper left corner of the screen.

3.2 Information Capture for Option Installation

If your system does NOT have Exam Split option, skip this section. Perform these steps before powering down your current Operator Console:

  1. Open a Unix Shell and type the following:
    1. {ctuser@hostname} su -
    2. Password: <password>
      note: If the Password has not been modified by the site and is not known, please contact the Local GE Service.
    3. [root@hostname] ls -l ~ctuser/ves/.hesMode
      note: There are no spaces in the phrase ~ctuser/ves/.hesMode
  2. Examine the results.
    • If the results are similar to:

      -rw-r--r-- l ctuser users 0 Apr 3 12:43

      /usr/g/ctuser/ves/.hesMode

      The HES (Hard Exam Split) mode is configured.

    • If the results show 'No such file or directory', then VES (Virtual Exam Split) mode is configured.
  3. Record Exam Split Mode (Hard or Virtual). This info will be used during the LFC Options Installation.
  4. Close the Unix Shell.

4 Save System State (Approximately 5 minutes)
