Required conditions
Make sure all customer-purchased options are installed before running ICW. Any options added after running ICW will not be displayed.
A service key is required to launch the Installation and Calibration Wizard.


Safety
Before working in any GE Healthcare MR suite or performing any GE Healthcare service procedure, you must: Have read and understood all hazard conditions and safety requirements in the latest revision of the GE Healthcare MR Service Safety Manual (5452735). Have successfully completed all relevant GE Healthcare Environmental Health and Safety (EHS) courses (or for non-GE employees, equivalent workplace training courses). Comply with all site-specific training and workplace safety requirements. If you have any safety concerns at any time, do not begin work or immediately stop work and move to a safe location. Immediately contact your supervisor or site safety officer for instructions on how to proceed.

About this task

ICW installation mode is used for new installations and upgrades.

The left pane lists all tasks required to complete the installation.
Tasks must generally be completed in order, from top to bottom (tasks with prerequisites are grayed out until all prerequisites are completed). Non-grayed out tasks may be completed in any order or in parallel.
After a task is completed, click Check Status in the right pane. Completed tasks turn blue; failed tasks turn red.
ICW remains in installation mode until all tasks are successfully completed.

Note:

When running ICW, the calibration tools are launched and finalized from within the ICW interface.

Figure 2. ICW calibration tool interface

Note: (For software versions 29.0 and later)

Software version 29.0 introduces forced password changes on all user accounts to comply with minimum mandated security requirements for GE equipment.
Password changes are mandated on two instances:
- When booting the software for the first time.
- When rebooting the system after completion of Install In Spec.

When running these tools within ICW, some of the finalization tasks such as Doing a TPS reset or Saving information will be automatically completed by ICW.

Procedure

Before opening ICW for the first time, make sure all options purchased by the customer are installed.

Note:
The option key check is only done the first time the tool is used. Any change to the option key status after ICW has started will not be displayed.
From the Common Service Desktop select Calibrations > Installation and Calibration Wizard.

Use the following tables as a reference to identify what tasks are needed to complete each procedure within ICW.

Note:

Relaunching a completed task in ICW displays a dialog showing prerequisite tasks. You may want to rerun the prerequisites listed before rerunning the selected task.

Invoke ICW and check off	When you power up the host computer and see the login screen, click root login. Log in with the user name: root and password. Note: It is possible that the customer changed the default password. If you cannot log in, contact the customer for the correct password. Logging in as the root user automatically displays the Linux desktop and launches the Guided Install Starter window. Click No to ignore the Guided Install. Confirm that the service key is installed. Right-click on the Linux desktop to access the Root Menu and then select Start ICW. ICW screen shows: Mechanical Installation Record the start and end dates. Power on sequencing Answer the following questions: Have you filled chiller and lines with coolant? Is Magnet Monitor power connected to customer source? Have you completed system power on sequentially? Are the coolant leak checks done? Have you completed the E-Stop and E-Off functional checks? Software setup Answer the following questions: Has the GOC come with software pre-loaded? (Yes/No) If no, see Installing host system software (quick start). Does the system have the latest service pack software loaded? (Installing Service Packs) Have you loaded the customer Operator's Manual? If not, see Installing operator documentation (online help). Have you restored the Start Values for Calibration? If not, see Restore Start Values for Calibration. Make sure the system parameters (hardware and software) are correct by viewing the About box. It is available from the Tools pull-down menu by selecting `About MR Scanner`.	-
