Pinouts and signaling
This section describes the pinout diagrams for the DB-9 connector and RJ45 port
jacks.
Serial (Console) port pinouts
The Console port is a standard male DB-9 connector, as shown in Figure 40.
Most PC serial ports require a cable with a female DB-9 connector. However,
terminal connections will vary, requiring a cable with either a DB-9 or DB-25
connector, male or female.
Serial cable options between a y-series switch and a PC or terminal are shown in
Figure 41 on page 53.
Note: As indicated in Figure 41 on page 53 and Figure 42 on page 53, some of the
wires should not be connected. If you do connect the wires that are labeled
“Reserved”, you may get unexpected results with some terminals.
