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 34 on page 83 provides the pinout information for the RJ-45 to DB-9 serial port adapter.
