Local Control Panel Interconnects
The Intel
®
Local Control Panel module includes the control panel interface board and an
interposer board. Connectors on the control panel interface board are cabled to matching
connectors on the interposer board. When the pre-assembled control panel module is installed
into the chassis, a card edge connector on the interposer card is blind mated with a slot edge
connector on the backplane. This section will define the pin-out for each connector and header
found on both the control panel interface board and interposer board.
• A 64-pin card edge connector on the interposer board is used to route signals to/from
the backplane to the control panel interface board. The backplane is used as a conduit
for communication to the server board.
• Signals from the card edge connector are routed to control panel interface board through
matching 50-pin connectors on the interposer board and 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 control panel interface
board through matching 10-pin connectors on the interposer board and control panel
interface board. The 10-pin connectors are attached using a small 10-pin round cable.
• A 4-pin IPMI header (not used).
• A 4-pin NMI/Temp Sensor header.
The following tables provide the pin-outs for each connector.
