Peripheral Controller
The advanced integrated peripheral controller supports two serial ports,
one parallel port, diskette drive, PS/2-compatible keyboard and mouse,
and integrated Real Time Clock (RTC). The system provides the
connector interface for each port.
Serial Ports
Both serial ports are relocatable. Each serial port can be set to one of
four different COM ports and can be enabled separately. When
disabled, serial port interrupts are available to add-in boards.
Parallel Port
One IEEE 1284-compatible 25-pin bidirectional EPP (supporting levels
1.7 and 1.9) parallel port is provided. BIOS programming enables the
parallel port and determines the port address and interrupt. When
disabled, the interrupt is available to add-in boards.
External Device Connectors
The external I/O connectors provide support for a PS/2 compatible
mouse and a keyboard, connectors for VGA monitor, 2 serial port
connectors, a parallel port connector and two USB connections.
System Board Management Controller (BMC)
Server management is concentrated in the System Board Management
Controller (BMC). The BMC and associated circuitry are powered from
a 5Vdc standby voltage, which remains active when system power is
switched off.
The BMC supports the Emergency Management Port (EMP) Console
which allows remote server management via a modem or direct
connection to a manager system. Events monitored by the manager
system include over-temperature and over-voltage conditions, fan
failure, or chassis intrusion.
Information on the Emergency Management Port (EMP) Console may be
found in Appendix C of this User's Guide.
