COM (Serial) ports
COM 1 (DB9)
BMC COM port (COM 2)
The serial ports are asynchronous communi-
cation ports with 16C550A-compatible UARTs
that can be used with modems, serial print-
ers, remote display terminals, and other serial
devices.
The three COM ports support RS232 — one
DB9 connector at the rear side and one inter-
nal pin-header connector for monitoring the
BMC.
