Remote access to the control console

You can access the control console through Telnet or Secure SHell (SSH), depending on which is enabled. (An Administrator can enable these access methods through the Telnet/SSH option of the Network menu.) By default, Telnet is enabled. Enabling SSH automatically disables Telnet.

Telnet for basic access. Telnet provides the basic security of authentication by user name and password, but not the high-security benefits of encryption. To use Telnet to access the control console from any computer on the same subnet:

1.At a command prompt, type telnet and the System IP address for the Rack PDU (when the PDU uses the default Telnet port of 23), and then press ENTER. For example:

telnet 139.225.6.133

If the PDU uses a non-default port number (between 5000 and 32768), you need to include a colon or a space (depending on your Telnet client) after the IP address and then enter the port number.

2.Enter the user name and password (by default, apc and apc for an Administrator, or device and apc for a Device Manager).

SSH for high-security access. If you use the high security of SSL for the Web interface, use Secure SHell (SSH) for access to the control console. SSH encrypts user names, passwords and transmitted data.

The interface, user accounts, and user access rights are the same whether you access the control console through SSH or Telnet, but to use SSH, you must first configure SSH and have an SSH client program installed on your computer.
