RPM Ports and Cables
This chapter describes standard RPM cables and adapter pin assignments.
• Connecting to the Console and Auxiliary Ports
• Connecting to the 10/100 Ethernet Management Port
There are three ports on the RPM:
• Console: A Universal Asynchronous Receiver/Transmitter (UART) port with an RJ-45 jack, is used for
system configuration and monitoring. Modem connections are not supported on this port.
• Auxiliary: A UART port with an RJ-45 jack that allows modem access to the system from a remote
location.
• 10/100 Ethernet: A 10/100 Ethernet port that is the Management port, which is a channel to download
images and manage the system. You must provide a cable terminated with an RJ-45 style connector to
attach to this port.
Connecting to the Console and Auxiliary Ports
The console and auxiliary ports are asynchronous serial ports. If you connect a device to these ports, it
must be capable of asynchronous transmission. Your terminal or terminal emulation mode must be set to
VT100 with the following settings:
• 9600 baud rate (to avoid autobaud input, the default is set to a 9600 bps baud rate)
• No parity
• 8 data bits
• 1 stop bit
• Window Terminal Emulator option set to NO
• 24 lines X 80 characters
• No flow control (console port only)
• Hardware flow control (RTS/CTS) (for auxiliary port only)
Cable and Adapter Pin Assignments
Use the E-Series Console port on the RPM to connect to a terminal port, PC serial port, or a terminal
server to configure and monitor your system. Use the E-Series Auxiliary port on the RPM to connect to a
modem.
Both the Console and Auxiliary port are RJ-45 ports.
Figure 8-1 displays the pinouts in an RJ-45 port.
