Connecting a Terminal to the Console Port
The console port is a serial RS-232 interface port that enables a
connection to a terminal for performing switch monitoring and
configuration functions. The terminal may be a PC or workstation running
terminal emulation software, or a terminal configured as a Data Terminal
Equipment (DTE) connection. Alternatively, this port can be connected to
an external modem to enable remote dial-in management. You can use
the out-of-band management program (described in the Management
Guide) over a standard modem connection.
If you connect a terminal to the console port prior to powering on the
switch, you can observe the progress and results of the power-on self test
as the switch goes through its initialization process. See “Powering the
Switch” on page 23.
The console port is configured as a standard RS-232 connection using a
male DB-9 connector (see Table A-1 for pinouts). A null-modem wired
RS-232 cable is supplied with the switch for connecting to this interface.
This cable is shielded to comply with emissions regulations and
requirements.
Console Port (Out-of-Band) Connections
To connect the VH-4802 console port to a terminal, do the following:
1. Connect a VT100 compatible terminal or a PC running a terminal
emulation program to the console port (Figure 2-3). Use the null-
modem cable provided with the switch, or use a null-modem
connection that is compatible with the console port pin assignments
shown in Appendix A.

2. Connect one end of the interface cable directly to the switch’s
console port and tighten the retaining screws.
