Accessing the Console Port

To access the console port, follow these steps:

For the console port pinout, refer to Accessing the RJ-45 Console Port with a DB-9 Adapter.

1. Install an RJ-45 copper cable into the console port. Use a rollover (crossover) cable to connect the console port to a

terminal server.

2. Connect the other end of the cable to the DTE terminal server.

3. Terminal settings on the console port cannot be changed in the software and are set as follows:

● 115200 baud rate

● No parity

● 8 data bits

● 1 stop bit

● No flow control

Pin Assignments

You can connect to the console using a RJ-45 to RJ-45 rollover cable and a RJ-45 to DB-9 female DTE adapter to a terminal

server (for example, a PC).

The pin assignments between the console and a DTE terminal server are as follows:

Accessing the CLI Interface and Running Scripts

Using SSH

In addition to the capability to access a device using a console connection or a Telnet session, you can also use SSH for secure,

protected communication with the device. You can open an SSH session and run commands or script files. This method of

connectivity is supported with S4810, S4048–ON, S3048–ON, S4820T, and Z9000 switches and provides a reliable, safe

communication mechanism.

Entering CLI commands Using an SSH Connection

You can run CLI commands by entering any one of the following syntax to connect to a switch using the preconfigured user

credentials using SSH:

ssh username@hostname <CLI Command>
