Sun StorEdge™L7 Decision Tree

The purpose of the Sun StorEdge L7 Decision Tree is to identify a logical sequence of events to

troubleshoot a Sun StorEdge L7 autoloader based upon the error message displayed on the LCD.

Since there are no Field Replaceable Unit (FRU) items available for servicing a StorEdge L7

autoloader , failure to successfully clear the error message after performing the steps outlined in

this decision tree will result in autoloader replacement.
