Restore Data to the Monitor
The CPU PCBA contains a USB flash drive PCBA that stores user-
created Custom Trends, as well as Citrix certificates required for the
DNA feature. These procedures outline the steps for successful
restoration of this data to your monitor when replacing the CPU
Flash Drive PCBA.
1 Remove and replace the CPU as specified in CPU PCB on
page 4-11.
2 Complete replacement of the CPU PCBA transfers a
nonformatted and nonprogrammed USB drive PCBA into the
qube monitor. Refer to
Figure 4-7 on page 4-13 to identify the
location of the USB drive.
Select Option 1: Exchange the USB Drive PCBAs or Option 2: Format
the USB Drive as the next step. Use Option 1 if the USB Flash Drive
PCBA currently functions with no errors.
Option 1: Exchange the USB Drive PCBAs
To maintain the user-created customized trends and Citrix
certificates in the USB drive, exchange the USB drives between the
defective CPU PCBA and the new CPU PCBA.
1 Locate the USB Drive is on the back side of the CPU PCBA. Refer
to
Figure 4-7 on page 4-13 for the location of the USB Drive.
2 Remove the screw holding the USB drive to the CPU board.
3 Lift the USB drive PCBA away from the defective CPU PCBA.
4 Remove the USB drive PCBA from the replacement CPU PCBA.
5 Exchange the USB drives between the two CPU PCBAs.
6 Reassemble the monitor as described in Assembly/Disassembly
Procedures on page 4-7.
Option 2: Format the USB Drive
The factory does not format the USB flash drive that is on the
replacement CPU PCBA. A built-in software utility in the extended
diagnostics menu in the monitor formats the USB drive. If the
software utility in the monitor does not format the USB drive, the
message:
System Software failure. Review error log for further
details shows after the power-ON self tests complete.
Note:
If you receive this message, format the new USB drive and
manually reprogram the user-defined Trends and DNA (Citrix)
certificates.
