The 2U/4U library is always online, except for when the user enters the Service
Library area. A warning message appears stating that the library should be taken

means of communication. Before performing any service functions, ensure the host
is not performing any data writing or retrieval.
The Service Menu contains the following items:
v Library Verify - an overall library diagnostic
v Run Tests - other library diagnostics
v Service - diagnostics and procedures for servicing the drive
v Display Contrast - setting the display from light to dark
Service: Library Verify
