Connecting your appliance to an ASCII terminal console
About the ASCII terminal console
The ASCII terminal console enables you to monitor the boot process, helps you configure your appliance after it boots, and enables you to perform system administration. It is normally connected to the appliance with a DB-9 serial cable, attached to a DB-9 to RJ-45 console adapter, and then connected through the RJ-45 console port on the CPU module at the rear of the appliance.

DB-9 to RJ-45 console adapter pin connections
You use the DB-9 to RJ-45 console adapter to connect the ASCII terminal console to your appliance. Its purpose is to convert the RJ-45 pinout on the appliance to the DB-9 pinout, like those on other NetApp products, and all PCs.
The following table lists the console adapter pin number connections between the PC-style DB-9 male connector and the RJ-45 connection on your appliance.
