DB-9 (RS-232-D) Console/Comm Port connector
The DB-9 Console/Comm Port connector (Figure 90) 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.
