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.

9.2 Intel Local Control Panel Interconnects
®
The Intel Local Control Panel module includes the Intel
and a USB interface board. Connectors on the Intel
USB interface board are cabled to matching connectors on the hot-swap backplane. This
section will define the pin-out for each connector and header found on both the Intel
Control Panel interface board and interposer board.
•
Signals from the card edge connector are routed to the Intel
interface board through matching 50-pin connectors on the interposer board and the
®
Intel Local Control Panel interface board. The 50-pin connectors are attached using a
small 50-pin flat cable.
•
USB signals from the card edge connector are routed to the Intel
interface board through matching 10-pin connectors on the interposer board and the
®
Intel Local Control Panel interface board. The 10-pin connectors are attached using a
small 10-pin round cable.
•
A 4-pin NMI/Temp Sensor Header (cables between the Intel
interface board and the USB interface board).
The following tables provide the pin-outs for each connector.
