System Diagnostics Fault History
The SubDrive Utility continuously monitors system performance and can detect a variety of abnormal con
-
ditions. In many cases, the drive will compensate as needed to maintain continuous system operation; how
-
ever, if there is a high risk of equipment damage, the drive will stop the system and display the fault
condition. If possible, the drive will try to restart itself when the fault condition subsides.
Each time a fault is detected in the system, the drive records the fault with the date and time the fault was
detected. The event log can be written to a USB flash drive for subsequent viewing or email.
NOTE:
A good quality, USB 2.0 compliant or newer device is required. Some older or lower-cost devices may
not be recognized by the drive.
Use the following procedure to download the log file:
1.
Remove power from the drive and allow 5 minutes for internal voltage to dissipate.
2. Remove the drive cover.
3. Insert the USB device into the USB port on the lower-left corner of the circuit board.
4. Reinstall the drive cover before applying power to the drive.
5. Apply power to the drive. The firmware readout procedure will begin automatically.
NOTE:
If the USB device contains a SubDrive Utility firmware file that is different than the firmware cur
-
rently installed on the drive, the firmware update procedure will begin, and a log file will not be written.
Refer to
“Firmware Update Procedure” on page 37
for more information.
