Cabling the System Processor Serial Ports

The system processor serial ports provide the
following connectivity options:
One serial (RS-232C) modem port for an external
modem connection
One serial (RS-232C) terminal port for a terminal
connection
Pinouts for the serial ports are shown in
and Table 4-4.
To connect to either the modem port or the
terminal port:
Attach the female DB-9 connector to the selected
1
modem or terminal port.
Secure the connector to the port using the
2
connector screws.
Attach the other end of the serial cable to your
3
modem or terminal.
Figure 4-28 shows the cabling of the system
processor.
You can also access the system processor through
any Ethernet port using telnet or rlogin.
