To use the Console/Comm port, you need the following equipment:
•A VT100 or ANSI-compatible terminal, or a PC with a serial port and the ability to emulate a VT100 terminal.
Configure the terminal settings as follows:
-- 9600 baud
-- No parity
-- 8 bits
-- 1 stop bit
-- Flow control set to Xon/Xoff
-- Window Terminal Emulator option set to NO
-- Terminal Preferences: Function, Arrow, and Control keys active
-- Buffer size set to 24
•A UL-listed straight-through RS-232 cable with a female DB-9 connector for the console port on the switch.
The other end of the cable must have a connector appropriate to the serial port on your computer or terminal. (Most terminals or computers use a male DB-25 connector.)
Any cable connected to the console port must be shielded to comply with emissions regulations and requirements.
See “DB-9 (RS-232-D) Console/Comm Port Connector” on page F-5 for a description of the pin assignments.
Cable should be a STRAIGHT THROUGH. After connecting, enter a CNTRL-Y to get started.
Cable Config, straight out of the manual:
The DB-9 Console/Comm Port connector (Figure F-4) is configured as a data
communications equipment (DCE) connector. The DSR and CTS signal outputs
are always asserted; the CD, DTR, RTS, and RI signal inputs are not used. This
configuration enables a management station (a PC or console terminal) to connect
directly to the switch using a straight-through cable.

Table F-2 lists the DB-9 Console/Comm Port connector pin assignments.
