Intel® SHG2 DP Server Board Technical Product Specification Connections

Revision 1.0 Intel Order Number C11343-001

The COM2 serial port can be used either as an emergency management port (EMP) or as a

normal serial port. As an EMP, COM2 is used as a communication path by the Server

Management RS-232 connection to the BMC. This port can provide a level of emergency

management through an external modem. The RS-232 connection can be monitored by the

BMC when the system is in a powered down (standby) state.

Table 52 lists the signals present on the COM2 serial port header.
