Advanced System Management dual serial port:
The Advanced System Management PCI Adapter contains
a dual serial port. The port has an external connector that
can be used to attach to a Y-cable that is shipped with the
server. The serial connectors on the Y-cable and the
pin-number assignments are the same as for the system
serial ports. This Y-cable can be used to attach to a
modem that is dedicated to communication with the
Advanced System Management PCI Adapter.
You can obtain a listing of compatible modems and related
information by accessing the following address:

Advanced System Management Interconnect
port:
The Advanced System Management PCI Adapter
contains an Advanced System Management Interconnect
port. The port has an external connector that must be
attached to an optional Y-cable that provides for chaining
other compatible service processors for remote access.
To obtain an optional Y-cable, contact an IBM reseller or
IBM marketing representative.
The following table shows the pin-number assignments for
the connectors used by the Advanced System
Management Interconnect bus port.
