Indicators, Messages, and Codes 13
• The power button provides the ability to soft switch the power cycling to the system.
• The two system identification buttons on the front and back panels can be used to locate a
particular system within a rack. When one of these buttons is pushed or the system
management software is used to identify the system, the blue system status indicators on the
front and back of the system blink. (To stop the indicator from blinking press one of the
identification buttons a second time, or use the systems management software.)
The front panel also incorporates a USB connector that is accessible when the bezel is removed.
