CONNECTING TO THE CONSOLE PORT
This port is used to connect a console device to the switch through a straight-
through UTP cable and an RJ-45-to-DB-9 serial converter. The console device
can be a PC or workstation running a VT-100 terminal emulator, or a VT-100
terminal. An RJ-45-to-DB-9 converter is supplied with the unit for connecting to
a RS-232 serial DB-9 DTE port, as illustrated below. The pin assignments used in
the RJ-45-to-DB-9 converter are described below.
