A system identification button on the front panel can be used to locate a particular system within a rack. When one of these buttons is pushed or the systems
management software is used to identify the system, the blue system status indicator on the front of the system blinks. (To stop the indicator from blinking,
press the identification button a second time, or use the systems management software.) The optional locking system bezel incorporates blue and amber
system status indicators. The blue indicator lights up when the system is operating correctly.
