Serial Interfaces
The Super I/O device provides two serial full−duplex RS232 interfaces. Supported baud
rates are: 600, 1200, 2400, 4800, 9600, 19200, 38400 and 115200 kb/s. Both serial interfaces
are +/− 15 KV ESD protected.

are +/− 15 KV ESD protected.
Both interfaces correspond to the blade
′s serial interface ports 2 and 4. Serial interface port
2 is routed via a zone 3 connector to an installed RTM. Serial interface port 4 is accessible
via an installed CMC module. The BIOS maps the serial interface ports to the desired I/O
addresses (COM ports) and interrupts.
