2 OverviewThe 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: These instructions and procedural flow are structured for performing a Load From Cold on a system with the same versionsoftware. In other words, a reload of the same software release. If the system being loaded is running an earlier release ofsoftware, refer to the Software Upgrade procedure in the Field Modification Instructions (FMI) for the appropriate softwarerelease. Additional instructions may be needed when upgrading software, and this information will only be found in the FMIinstructions.

NOTE: 11HW12.5 software revision supports Dose Check feature/functionality. Software revision 11MW4.1 does not include DoseCheck feature/functionality.

4 Procedure

4.1 Software Deliverable for GOC6 Series Consoles

1. CTT Operating System, Version 5.3.11

2. CT Applications Software

4.2 Pre-LFC Checks and Information Gathering

1. Confirm that a current System State Backup Media is on site. If unsure of the status of the System State, execute SystemState Save and Restore procedure found in the Software Chapter of this manual. Save a System State Backup to either DVD-RAM or USB Media.

2. Remove all media from MOD and DVD Peripheral Towers before starting the OS Load of the LFC process.

4.3 Operating Software (OS) Load

1. Unplug the Hospital Network (HSP - J26) cable from rear Console bulkhead.

2. Label the cable as HSP - J26 (if necessary) and set it aside during LFC.

3. Remove the Operator Console front cover per the prescribed procedure Console Cover Removal and Installation.

4. Insert the OS Disk into the Host Computer DVD Drive. See the following illustrations.

Illustration 1: GOC6 Host Computer DVD Drive Location

Illustration 2: GOC6.5 Host Computer DVD Drive Location



5. Shutdown and Power Cycle Operator Console:

a. Using the toolchest, open a Terminal Window.

i. Type: {ctuser@hostname}halt

ii. Wait for System Halted message to appear on the monitors.

Illustration 3: Monitor Display - System Halted

b. Turn Off Operator Console power. Wait 30 seconds, then turn power On.

6. As the Host Computer restarts, the boot process messages appear. After the booting process completes the boot: promptappears.

7. At the “boot:” prompt, type the following:

Type: boot: GEHC2

Illustration 4: Monitor Display - Boot Prompt



8. After the OS is loaded on the Host Computer, the Complete Window appears.

Illustration 5: Monitor Display - OS Load Complete

9. Remove the OS Disk from the Host Computer DVD drive when it ejects and close the tray. Press [Enter] to Reboot.

10. The Host Computer begins to reboot.



NOTE: Do not insert the Applications Software DVD into the Host Computer until the Host Computer has completed rebootingand a Terminal Window appears, displaying the prompt: [root@localhost ~]#.

Illustration 6: Terminal Window - After OS Load and Reboot

NOTE: GOC 6.5 Operator Consoles Only:

Dual Monitor Displays: From this point in the procedure, the dual monitor display will appear reversed (Right monitorvideo will display on Left monitor and Left monitor video will display on Right monitor). This is normal, do not movemonitor video cables! This also impacts the behavior of the mouse cursor. The mouse cursor will not cross over themiddle junction of the dual monitor display. Instead the mouse cursor will need to be dragged to the outside of thedual monitor display in order to change from one monitor to the next. To place the mouse on the right monitor, dragthe mouse outside the left monitor’s LEFT side. The mouse will then appear on the right monitor. This condition will beresolved after the Application Software is loaded on the system.

Error Window After OS Bootup: After the OS Bootup, an Error Window will appear. This is normal and is related to thenew Host Computer's (HP Z400) on board audio controller. When Error Window appears, close the error window byclicking on the [Close] button. This error is the result of driver configuration for the on-board audio hardware and willbe resolved once the Application Software load is completed on the system.

Illustration 7: GOC6.5 Error Window - After OS Load and Reboot

NOTE: GOC 6 Operator Consoles Only:

Warning Window During APPS Load: After the OS Bootup and during the APPS load, a Warning Window will appear.This is normal and is related to the Host Computer's (HP xw8400) on board audio controller. When Warning Windowappears, ignore it (take no action). This warning message is the result of driver configuration for the on-board audiohardware and will be resolved once the Application Software load is completed on the system.
