HP EML E-series Tape Libraries - Manual (Page 47)

• If an error condition occurs while the library is timed-out, the backlight comes on for 60 minutes.
If the OCP is touched during this 60-minute period, the library reverts to a normal 5-minute period
before a timeout. Otherwise, the library re-enters a normal timeout state after 60 minutes.
For certain functions, the timeout feature is disabled and re-enabled when the function completes. This
occurs:
• During an operation and until the operation completes. For example, the OCP does not time
out while a tape drive cleaning operation is in progress but waits for the operation to complete
before starting the 5-minute timeout counter.
• While displaying the results of any test operation. Select the Cancel or OK button to return to
the test menu screen.
• When displaying an error report or menu after an error. The screen is treated as temporarily
thumbtacked, which clears the passworded screens after the normal timeout period, but displays
the screen until it is acknowledged.
• When success or failure messages display for an operation. The screen is temporarily
thumbtacked, clearing the passworded screens after the normal timeout period, but the screen is
displayed until acknowledged.
