RJ-45 to DB-9 Serial Port Adapter Pinout Information
The console port is an RS-232 serial interface that uses an RJ-45 connector to connect
to a management device such as a PC or a laptop. If your laptop or PC does not have a
DB-9 male connector pin and you want to connect your laptop or PC to the device, use
a combination of the RJ-45 to DB-9 female adapter along with a USB to DB-9 male
adapter.
Table 52 on page 118 provides the pinout information for the RJ-45 to DB-9 serial port
adapter.
