The Diagnostic Port

The diagnostic port on the rear panel of the master hub is used to establish a connection with a device to allow in-band or out-of-band management of the DFE-2600 series hubs stacked with it. The console device connected to the diagnostic port can be a terminal (or a computer running terminal-emulating software) or a PC running TCP/IP TELNET.

Diagnostic Port Connection

The diagnostic port is an RS-232 DCE interface. To establish a physical line connection with an RS-232 serial port (DTE) on a PC acting as a console, all you need is a straight serial cable, as shown in the diagram below. Note that

aDCE-to-DTE connection requires a straight serial cable, not a null-modem cable.

You can use the diagnostic port on a DFE-2600 series master hub to connect a VT100-compatible terminal or a computer running an ordinary terminal emulation program (such as the terminal program included with the Windows operating system). In all cases, your terminal parameters will need to be set to:

♦VT-100/ANSI compatible,

♦Arrow keys enabled,

♦9600 baud,

♦8 data bits,

♦No parity,

♦1 stop bit.

You can also access the same functions over a TELNET link. Once you have set an IP address for your hub (see In-Band Setup Instructions on page 37),
