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>
or
echo <CLI Command> | ssh admin@hostname
The SSH server transmits the terminal commands to the CLI shell and the results are displayed on the screen non-interactively.
