Section 2

Workstation Updates Workstation Uninterruptible Power Supply (UPS) The OEC 9900 Elite Workstation now contains an Uninterruptible Power Supply (UPS). The UPS provides emergency backup power to the Workstation in the event of an unexpected power loss. If power is unexpectedly lost, the UPS allows the system time to save current images and to shutdown normally.

UPS Operation The UPS is not active until the system startup sequence is complete. The startup sequence is complete when the Login or Patient Information screen is displayed on the right hand monitor. A power loss (pressing the power switch, unplugging the system, etc.) during the startup sequence causes the system to record that an improper shutdown has occurred. An improper shutdown results in a file system check the next time the Workstation is started. The file system check can take up to 5 minutes to complete.

First Time Workstation Setup The first time the Workstation is set up or after an extended time in storage, the batteries in the UPS need several hours to charge before the UPS can be completely effective in case of an unexpected power loss. Charging of the UPS batteries begins automatically when the Workstation is plugged in and does not affect operation of the Workstation. If the Workstation is connected to a compatible C-arm, the C-arm could require several hours to charge its batteries after the system is plugged in initially or after an extended period in storage. Note:

For more information on C-arm charging times and requirements, refer to “C-arm Battery Charging Guidelines” in this update and to the information on powering on and battery charging in the OEC 9900 Elite C-arm Operator Manual.

Page 2-1

OEC 9900 Elite Operator Manual

Starting, Shutting Down, and Restarting the System Since the UPS is not active until the system startup sequence is completed, a power loss (pressing the power switch, unplugging the system, etc.) during the startup sequence causes the system to record that an improper shutdown has occurred. An improper shutdown results in a file system check the next time the Workstation is started. See “File System Check” below for more information.

Starting the System CAUTION Data loss can occur if the system startup sequence is interrupted. Do not press the power switch or unplug the Workstation until system startup is complete. System startup is complete when the Login screen or the Patient Information screen is displayed on the right monitor. Wait for the system startup sequence to complete before pressing the power switch to shutdown the system. UPS protection is not active until the system has completed the startup sequence. 1. To start the system, press the power switch located on the front of the system.

Update

File System Check WARNING Do not press the Workstation power switch before the system completes the start up sequence. Pressing the power switch before start up has completed could result in loss of data and system start up failures requiring a Service Representative to restore the system. Note:

Depending on the version of the software on your Workstation the following screens may not appear on the Workstation monitor. The system file check is still performed and may take up to 5 minutes to complete. If the system fails to start after 5 minutes, the file check has failed and you must call your Service Representative to restore the system.

A power loss (pressing the power switch, unplugging the system, etc.) during the startup sequence causes the system to record that an improper shutdown has occurred. An improper shutdown results in a file system check the next time the Workstation is started. When a file system check is required, the Workstation begins the startup process and then displays a screen similar to the following.

Figure 2-2. File System Check in Progress As the Workstation checks the file system, any problems encountered are repaired if possible. This check can take up to five minutes to complete. Do not turn off the Workstation while a system file check is in progress. When the file system check is completed successfully, a screen similar to the following is displayed.

Page 2-3

OEC 9900 Elite Operator Manual

Figure 2-3. File System Check Completed Successfully The system continues the startup sequence. System startup is complete when the Login or Patient Information screen is displayed. If the file system check fails, a screen similar to following is displayed.

Figure 2-4. File System Check Failed If a file system check fails, the system is no longer usable and you must call your Service Representative to restore the system. Turn off the Workstation and call your Service Representative.

Shutting Down the System 1. To shut the system down normally, press the power switch on the front of the system. 2. The power switch begins to blink as the system shuts down. A shutdown message is displayed on the right monitor. Shutdown time varies according to what the system was doing when the power switch was pressed. The power switch continues to blink until the system has shutdown successfully and then turns off. Shutdown should take 8 to 15 seconds.

CAUTION If the system fails to shutdown normally, call for service. Note:

Once the system shutdown message is displayed on the right monitor, the shutdown cannot be aborted. You must wait for the shutdown to finish before you can restart the system.

Note:

Because the system contains a UPS, shutting down using the power switch does not completely remove power from the system. To remove power, shutdown the system and unplug the system from the wall socket after normal shutdown is complete. Never unplug the power cord until shutdown is complete and power is off.

Restarting the System 1. To restart the Workstation, shutdown the system normally using the power switch on the front of the system. A shutdown message is displayed on the right monitor and the power switch blinks as the system shuts down. The power switch continues blinking until the system shuts down successfully and then turns off. 2. After the system shuts down, wait 10 seconds and then press the power switch to restart the system. The power switch lights up as the system starts up. Startup failures can result when restarting the Workstation if you do not wait 10 seconds after shutdown is complete before restarting the Workstation. If the 10 second interval is not allowed before restart, the system may fail to restart properly. Several error messages or other symptoms may occur during the restart including a failure to communicate with the UPS, an inoperable right monitor touch screen, or disabling of X-rays. If these symptoms occur, allow the system to startup completely, displaying either the Login or the Patient Information screen, and then press the power switch to allow the system to shut down properly. Wait the required 10 seconds after shutdown and restart the system using the power switch.
