5-13-2 Overview
The AC Power’s main tasks are to supply the various internal subsystems with AC power and to 
galvanically isolate the scanner from the on site Mains Power System. To reduce inrush current, an 
inrush current limiter as well as an EMI filter. Voltage to peripherals can be configured to either 115 VAC 
or 230 VAC. The AC Power also controls and supplies the 20VAC needed by the systems cooling fan.
5-13-3 AC Power PWB
The mains cord has plugs in both ends. A female plug connects to the scanner and a male plug to the 
mains outlet on site.
The mains voltage is routed via an EMI filter to the Mains Switch, located on the rear of the system.
The Mains Switch is of the auto fuse type, if for some reason the current grows to high, the switch will 
automatically break the power.
From the Mains Switch, the AC power is routed via an Inrush Current Limiter (titled: Inrush Limiter in 
Figure 5-39) to a internal outlet connector for the Mains Transformer.Figure 5-39   AC Power Distribution

5-13-3AC Power PWB (cont’d)
The Transformer is the galvanic barrier between the rest of the scanner and the on site AC Mains.
Input voltage to the transformer can be either 230VAC or 115 VAC (two different part numbers/FRUs). 
The configuration of the plug on the cable to the AC Transformer is different for the two AC Voltages.
From the AC Transformer, there are three outlets;
• 20 VAC
• 115 VAC
• 230 VAC
The 20 VAC is routed via the fan regulator to the system fan. (See separate description, Chapter 5 - Air 
Flow Control).
The 115 VAC is routed via a fuse to an AC Voltage selector, used for selecting the right output voltage 
for the Peripherals outlet and the Monitor. (The alternative voltage to this outlet is 230 VAC.)
The 230 VAC output from the Transformer is routed via a fuse and distributed to the AC Voltage selector 
for the Peripherals outlet and to the following AC outlets:
• Modem
• Back End Processor
• Card Rack

5-14-3 Wheels/Brakes
Check that the brakes and direction locks function as described below.
NOTE: The swivel lock and brake cannot be engaged (pressed down) at the same time since pressing the main 
brake releases the swivel lock and pressing the swivel lock releases the main brake. Therefore, if the 
swivel lock is engaged you need to press the main brake pedal (#2) twice to lock the scanner from 
rolling. Once will release the swivel lock and once again will engage the main brake in full lock as stated 
in step 1. Table 5-33     Brakes and Direction Lock Instructions

Air Flow Control
5-15-1 Air Flow Distribution
The fan at the rear of the scanner draws air into the scanner, through the foam filter, and pushes it 
through a flange that moves the air into a cavity on top of the card rack.
Air holes in the bottom of this cavity allow the air to move down through the card rack. Air exits the card 
rack through holes on its internal side panel into the interior of the scanner near the rear of the Backend 
Processor.
The internal fan in the Backend processor draws the air into the PC allowing it to pass through the 
interior of the PC, and exit the lower front area of the scanner.
Section 5-16
Service Platform
5-16-1 Introduction
The Service Platform contains a set of software modules that are common to all ultrasound and 
cardiology systems containing a PC backend. This web-enabled technology provides linkage to e-
Services, e-Commerce, and the iCenter, making GE’s scanners more e-enabled than ever. The Service 
Platform will increase service productivity and reduce training and service costs.
5-16-2iLinq Interactive Platform Features
Many of the services of the Service Platform come from its integration with iLinq. The following sections 
contain a brief introduction of iLinq’s features. Detailed information can be found in the LOGIQ™ 9 User 
Manual. (Direction 2309819-100.)
5-16-2-1 Web Server/Browser
The Service platform and other Service software use the iLinq web server and the Netscape® browser.
5-16-2-2 Connectivity*
This feature provides basic connectivity between the scanner and the OnLine Center (OLC).
5-16-2-3 Configuration
This feature provides for the interfaces to configure various iLinq parameters.
5-16-2-4 Contact GE*
Allows for an on-screen one-touch button used to contact the OnLine Center and describe problems 
with their scanner in an easy and convenient way.
5-16-2-5 Interactive Application
The main application is displayed in the form of HTML pages whenever the Netscape® browser starts. 
This is the entry point for any user to start any iLinq application.
NOTE: * These features that allow the customer to contact the GE OnLine Center are available for Warranty 
and Contract customers only.

5-16-3 Global Service User Interface (GSUI)
5-16-3-1 Internationalization
The user interface provided by the service platform is designed for GE personnel and as such is in 
English only. There is no multi-lingual capability built into the Service Interface.
5-16-3-2 Service Login
Select the wrench icon in the status bar at the bottom of the scan display screen.
This icon links the user or the Field Engineer (FE) to the service login screen.
5-16-3-3 Access / Security
The service interface has different access and security user levels. Each user is only granted access to 
the tools that are authorized for their use.
NOTE: A Service Dongle (part number 066E0703) is necessary for use by GE Service when performing 
proprietary level diagnostics. OnLine Center access to the scanner requires the password and they 
must have ‘Disruptive’ permission and customer input to run diagnostics.
NOTE: For a GE Field Engineer, the password changes at specific intervals. Access with the password is tied 
to the service key.
Every access request, whether successful or not, will be logged into a service access log that is 
viewable to authorized users.Figure 5-44   Login Screen for Global Service User Interface
