Establishing a console/terminal connection to the filer
About establishing a console/terminal connection
You establish a console/terminal connection to the filer for the following reasons:
- To observe the system responses on the terminal screen when the system is started
- To configure the filer after you start it
Protocol used by filer console port
The console port on your filer uses the three-wire protocol in which your filer uses only the RD, TD, and SG pins.
Note
The filer ignores the DCD, DSR, CTS, and RI input pins. You must set the flow control of your console/terminal to none and configure your console/terminal to ignore the DTR and RTS output pins.
Pin settings defined by RS-232
The following table lists pin settings defined by RS-232 for DB-9 and DB-25 ports.
Note
The DB-25 pin settings are listed in case you have a 25-pin console/terminal.
The arrows in the table represent the following directions:
