Sun Microsystems 440 manual Accessing the System Console Through a Terminal Server

To connect through the network management port, use the telnet command to the IP address you specified in Step 3 of the preceding procedure.

Accessing the System Console Through a Terminal Server

The following procedure assumes that you are accessing the system console by connecting a terminal server to the serial management port (SERIAL MGT) of the Netra 440 server.

▼To Access The System Console Through a Terminal Server

1.Complete the physical connection from the serial management port to your terminal server.

The serial management port on the Netra 440 server is a data terminal equipment (DTE) port. The pinouts for the serial management port correspond with the pinouts for the RJ-45 ports on the Serial Interface Breakout Cable supplied by Cisco for use with the Cisco AS2511-RJ terminal server. If you use a terminal server made by another manufacturer, check that the serial port pinouts of the Netra 440 server match those of the terminal server you plan to use.

If the pinouts for the server serial ports correspond with the pinouts for the RJ-45 ports on the terminal server, you have two connection options:

■Connect a serial interface breakout cable directly to the Netra 440 server. See “Accessing the System Controller” on page 16.

■Connect a serial interface breakout cable to a patch panel and use the straight- through patch cable (supplied by Sun) to connect the patch panel to the server.
