Mini Control Panel
7.2.2.1 System Status LED – BMC Initialization
When AC power is first applied to the system and 5V-STBY is present, the BMC controller on
the server board requires 30-35 seconds to initialize. During this time, the System Status LED
will Blink, alternating between Amber and Green, and the Power Button functionality of the
Control Panel is disabled, preventing the server from powering up. Once BMC initialization has
completed, the Status LED will stop blinking and the Power Button functionality is restored and
can be used to turn on the Server.

System Identification LED

The blue system identification LED is used to help identify a system for servicing. This is
especially useful when the system is installed when in a high density rack or cabinet that is
populated with several similar systems.
The Blue "System ID" LED can be illuminated using either of two mechanisms.
- By pressing the System ID Button on the system control panel the ID LED will display a
solid blue color, until the button is pressed again.
By issuing the appropriate hex IPMI "Chassis Identify" value, the ID LED will either Blink Blue for
15 seconds and turn off or will blink indefinitely until the appropriate hex IPMI Chassis Identify
value is issued to turn it off.

Internal Mini Control Panel Interconnects

All mini control panel signals are directed through a single 20-pin card edge interconnect. When
installed into the chassis, the mini control panel board blind mates to the hot-swap backplane.
