Before Contacting Customer Support

Errors that you may experience with your autoloader can range from simple connection problems to more complex hardware failure. Before you return your
autoloader, you may be able to fix the problem yourself by following some basic troubleshooting procedures.
Other than drive cleaning, there is no recommended routine maintenance of the Dell PowerVault 124T autoloader.
The operator control panel located at the front of the autoloader provides some troubleshooting capabilities, but is limited. The Remote Management Unit
provides more detailed information about the present state of the autoloader and past performance, and is more helpful for troubleshooting errors.
The following table describes the probable cause and suggested action for problems that you may encounter.

Table 1: Basic Troubleshooting

NOTICE: If you find that you must power cycle the autoloader, do not turn the power back on for at least 10 seconds after powering
down. This allows time for the power supply to completely discharge and ensure a complete system reset. If time is not allowed for the
discharge, the system may fail to boot properly and will display a blank LCD screen. Power cycle again, waiting at least 10 seconds, to
clear the problem.
