iBypass HD
Connect the Remote CLI Interface
To run the CLI remotely, connect a network cable from a switch to the Management port on the back of the iBypass HD
chassis. Use any computer with an SSH client to access the CLI over the network.
Note: __________________________________________________________________________________________________
Before connecting to the remote CLI interface for the first time, you must connect to the CLI locally and use the
procedure on page 21 to assign the iBypass HD an IP address that is available on your network.

Tip! ___________________________________________________________________________________________________
PuTTY is a freeware SSH client for Windows that can be downloaded from many sites on the Internet. You can use
PuTTY to access the iBypass HD CLI over an SSH connection.

To connect the CLI for remote use over the Management port:
1. Connect the iBypass HD Management port to a network switch using a network cable.
2. Open the iBypass HD from an SSH client on the network, using the IP address you assigned using the local CLI.
The SSH port is 22. The SSH client displays the shell login prompt.
Note: __________________________________________________________________________________________________
Your SSH client might give you a security warning if the RSA key in the iBypass HD is not known to the client, or
does not match the RSA key known to the client (because you have regenerated the RSA key in the iBypass HD).
Different SSH clients can require different actions to enable them to accept the new RSA key. For example, in OS X
and many Linux/Unix SSH clients, you need to locate the file known_hosts in the hidden directory /.ssh/ and remove
the entry for the iBypass HD IP address. Alternately, you can simply delete the file, removing all known hosts from
the SSH client.
