Instrument Sanitization Procedures
Instrument Sanitization Procedures
This section includes flowcharts that describe how to sanitize an instrument by
physical removal and replacement of the Disk Drive.
Application License Key Storage
Note that License keys for all Applications are stored in EEPROM on the A7
Midplane Assembly (as described in Item 18 of Table 4-1 on page 12).
Therefore, when replacing the Disk Drive, you do not need to back up and
restore the license keys.
Replacement of Disk Drive (Instruments without PC6S or PC7S)
Refer to the procedure below for details of how to perform this procedure.
IMPORTANT Ensure that the instrument software revision on the secondary non-classified
disk drive matches that of the classified drive in the controlled area.
If the non–classified drive receives a software upgrade, or if the non-classified
drive is replaced with a drive that contains a newer revision of software than
that of the classified drive, the classified drive will require a software upgrade
(inside the controlled area) to match the non-classified drive.
Items Required
To perform these tasks in a controlled area, you will need:
—1x Instrument
— 2x Disk Drives for the instrument
One drive (Disk Drive #1) stays permanently within the controlled area, and
the other (Disk Drive #2) stays permanently outside it
— 1x One-time writable media, plus 1x compatible writing device for the
non-controlled area and 1x reading device for the controlled area. See
“Selection of USB Memory Device” on page 31 for details.
Procedure
Steps below that appear on a yellow background take place in the controlled
area. All other steps take place in a non-controlled area.
Step Task
1 Receive new instrument from factory.
The instrument shipment may include a spare disk drive (additional drive) prepared by
the factory, which contains the same calibration data and software revision as the disk
drive in the instrument. If such a factory-prepared disk drive is present, you can skip
steps 3, 4, 6, 7, 9, and 10 below.
