4.2.2 Serial Ports
The I/O carrier provides two stacked RS-232C serial ports (the top one is COM1 and the bottom
one is COM2).
They are D-subminiature 9-pin connectors. Each serial port can be enabled sepa-
rately with the configuration control provided on the I/O carrier.
The COM2 serial port can be used either as an emergency management port or as a normal
serial port.
As an emergency management port, COM2 is used as a communication path by the
server management RS-232 connection to the FPC on the front panel board. This provides a
level of emergency management through an external modem. The RS-232 connection can be
monitored by the FPC when the system is in a powered down (standby) state. For additional
information, see the Emergency Management Port v1.0 Interface External Product Specification.
