Establishing a CLI Session
You can access the device's CLI using any of the following methods:
| ■ | RS-232: The device's CLI can be accessed through its RS-232 serial port, by connecting a VT100 terminal to it or using a terminal emulation program (e.g., HyperTerminal) with a PC. For connecting to the CLI through RS-232, see CLI. | 
| ■ | Secure SHell (SSH): The device's CLI can be accessed through its Ethernet interface by the SSH protocol using SSH client software. A popular and freeware SSH client software is PuTTY, which can be downloaded from https://www.putty.org. | 
| ■ | Telnet: The device's CLI can be accessed through its Ethernet interface by the Telnet protocol using Telnet client software. | 
The following procedure describes how to access the CLI through Telnet/SSH.
| ● | The CLI login credentials are the same as all the device's other management interfaces (such as Web interface). The default username and password is "Admin" and "Admin" (case-sensitive), respectively. To configure login credentials and management user accounts, see Configuring Management User Accounts. | 
| ● | After three consecutive failed login attempts because of incorrect credentials, the device ends the CLI session and you will need to re-establish it. | 
| ➢ | To establish a CLI session through Telnet or SSH: | 
| 1. | Connect the device to the network. | 
| 2. | Establish a Telnet or SSH session using the device's OAMP IP address. | 
| 3. | Log in to the session using the username and password assigned to the Admin user of the Web interface: | 
| a. | At the Username prompt, type the username, and then press Enter: | 
Username: Admin
| b. | At the Password prompt, type the password, and then press Enter: | 
Password: Admin
| c. | At the prompt, type the following, and then press Enter: | 
> enable
| d. | At the prompt, type the password again, and then press Enter: | 
Password: Admin
