Troubleshooting Flow Charts

0

The diagnostics flow chart series provide a guide to troubleshooting a malfunctioning CV70. The “Component Designations” section of this manual provides a table called Subsystem and Component Designations that identifies the acronyms used in this chapter to identify devices. Refer to the following chapters in this manual for additional information:

• • • • • •

System Architecture Component Designations Configuring a Remote Network Export Device Configuring DICOM Software Option Keys FRU Removal and Replacement Procedures

WARNING

The CV70 contains hazardous voltages that can range from 90 VAC to 264 VAC. These voltages can cause serious injury or death. ¹ Only authorized service personnel are permitted to remove protective covers and access the energized components of this system.

The system-troubleshooting flow chart is designed as a closed loop. The main flow chart branches to secondary flow charts, each of which returns to the main flow chart for continued troubleshooting. With this method, fault conditions involving more than one error may be resolved. The flow chart is not intended to resolve all possible fault conditions; it is designed to resolve 80% of typical field situations.

Using the Flow Chart

0

Always start at the top and check each item in the Check column. The chart on the next page provides details for each Check item. Example: The system does not boot correctly. Do not go directly to the “Boot-up” flow chart. First confirm power by checking the LED on the Host Module OEM Sub Panel. If this LED is OK, and the monitor LED is on, then proceed to the “Boot-up” flow chart. When the “Boot-up” flow chart tasks are complete, then confirm the remaining items.

Diagnostic LED Indicators

0

Several groups of diagnostic LED indicators are provided; these indicate system or component status.

System Status

0

Diagnostic light emitting diodes (LEDs), located on the side of the host module, provide indications of the boot progress, the system status, and some subsystem failures. The legend shown (Fig. 11 / p. 15) depicts the LED status for the Off (extinguished), On (illuminated), and flashing (On-Off) conditions. In the “Component Designations” section of this manual provides a table called Subsystem and Component Designations that identifies the acronyms used to identify devices.

Fig. 11: LED Legend

The status of the LEDs as they are progressively extinguished during the boot sequence are shown in (Fig. 12 / p. 16). The LED status after the boot sequence completes for systems with and without the DIMAQ-IP module connected, are shown in (Tab. 1 / p. 17).

NOTE

The LED designated with the V character represents the 5V supply. This LED illuminates when 5V power is available. The RTC LED indicates the operation of the real-time clock. The Windows 2000 operating system in the DIMAQ-IP boots during the sequence shown in (Fig. 12 / p. 16).

Corrupt Images and Clips

0

If corrupt images or clips display after pressing Review, the following failures can be the cause. 1. New images or clips produced by real-time scanning are corrupt, but images loaded from studies on the HDD or from a CD are not corrupt. Corruption of ultrasound images is caused by a failure in the host module or the failure of the image transfer path (serial). Inspect and test the host module and the serial path; replace the host module if necessary. 2. New images from real-time scanning are not corrupt, but images recalled from the HDD or from a CD are corrupt. The corruption of images loaded from the HDD or a CD is caused by the DIMAQ-IP software or by the CD-R/RW drive software. Reload the DIMAQ-IP software to resolve the problem.

SRAM Memory Clear

0

Overview

0

Background This procedure is valid for use with systems at software versions below 2.0. Battery-backed SRAM memory may become corrupt after an unexpected power loss during system operation. If this happens, the following may occur:

• The system may not power back up to imaging. • The system may display errors or display the message No System. Insert System Disk. Reloading system software may not be possible without first clearing battery-backed SRAM. When the problem occurs the Unknown file error messages are typically displayed before and after software reload attempts. Purpose This procedure describes how to clear the battery-backed SRAM so that the software can be reloaded. Two methods are provided: a software solution (recommended) and a hardware solution.

• Software Solution - This method uses the Memory Repair Disk to clear SRAM memory and is the most effective and recommended method.

• Hardware Solution - This method removes battery power from the SRAM in the Host module to clear the memory and is provided as a alternate to the recommended software method above.

CAUTION

Clearing SRAM memory clears system Software Option Keys, QuickSets, Preset data, and Service data. ¹ Obtain the Option Key MO disks and the Preset MO disk to restore the system to the previous operating condition. If Preset data, Service data, and QuickSets were not previously backed up to the Preset MO disk, manually reconfigured the system to customer preference. Clearing SRAM memory should not effect exam data stored on the DIMAQ-IP hard drive.

CAUTION

Reloading DIMAQ-IP software overwrites all data on the DIMAQ-IP hard drive. ¹ Therefore, before reloading DIMAQ-IP software, customer data on the DIMAQ-IP hard drive that must be maintained should be backed up to CD.
