Auxiliary Port Signals
Table 3-2 lists the signals used on the auxiliary port. The auxiliary port supports hardware flow control
and modem control.
Fast Ethernet Connection Equipment
The I/O controller is available with or without a Fast Ethernet port. The I/O controller with a Fast
Ethernet port is equipped with either a single MII port or an MII port and an RJ-45 port (only one port
can be used at a time). Although still supported by Cisco Systems, the I/O controller equipped with the
single MII port was discontinued as an orderable product in May 1998. The following sections explain
Fast Ethernet MII and RJ-45 connection equipment.
