6.5 SSI Control Panel Connector (J3H2)
The server board provides a 24-pin SSI control panel connector (J3H2) for use with non-Intel
chassis. The following table provides the pin-out for this connector.

The system BIOS combined with the Integrated BMC provide the functionality of the various
supported control panel buttons and LEDs. The following sections describe the supported
functionality of each control panel feature.
Note: Control panel features are also routed through the bridge board connector at location
J4G1, as is implemented in Intel
®
Server Systems configured using a bridge board and a hot-
swap backplane.
6.5.1 Power Button
The BIOS supports a front control panel power button. Pressing the power button initiates a
request that the Integrated BMC forwards to the ACPI power state machines in the chipset. It is
monitored by the Integrated BMC and does not directly control power on the power supply.
Power Button — Off to On
The Integrated BMC monitors the power button and the wake-up event signals from the
chipset. A transition from either source results in the Integrated BMC starting the power-
up sequence. Since the processors are not executing, the BIOS does not participate in
this sequence. The hardware receives the power good and reset signals from the
Integrated BMC and then transitions to an ON state.
