Establish Communications & Verify Drive
Configuration
If you cannot enable the drive, and examining LED conditions has not solved
your problem, then launch the Aries Support Tool and establish
communications with the drive. (For detailed instructions on establishing
communications, see “Establishing Communications” on page 74.)
If you are unable to establish communications, see “RS-232/485
Communication Problems“ on page 159.
Save the Configuration File
Because further troubleshooting steps can change the drive configuration,
upload the current drive configuration file, and save it to your personal
computer. This ensures you have a backup copy of the drive configuration.
To save a backup configuration file, use the Aries Support Tool.
