Battery Management System

USER’S GUIDE

®

From a command line interface, such as the command prompt on Windows operating systems, you can use FTP or Secure CoPy (SCP) to transfer the host key file. You must transfer the file to location /sec on the Battery Management System.

If you do not specify a host key file, the Battery Management System generates an RSA host key of 768 bits, instead of the 1024-bit RSA host key that the Wizard creates. The Battery

Management System can take up to 5 minutes to create this host key, and SSH is not accessible during that time.

•Display the fingerprint of the SSH host key for SSH versions 1 and 2. Most SSH clients display the fingerprint at the start of a session. Compare the fingerprint displayed by the client to the fingerprint that you recorded from the Web interface or control console of the Battery Management System.

If you are using SSH version 2, expect a noticeable delay when logging on to the control console of the Battery Management System. Although the delay is not long, it can

be mistaken for a problem because there is no explanatory message.
