10.  SSH Encryption
In addition to standard Telnet protocol, the Outlet Managed PDU also supports 
SSH connections, which provide secure, encrypted access via network.  In order to 
communicate with the Outlet Managed PDU using SSH protocol, your network node 
must include an appropriate SSH client.
Note that when the /K (Send SSH Key) command is invoked, the Outlet Managed 
PDU can also provide you with a public SSH key, which can be used to streamline 
connection to the Outlet Managed PDU when using SSH protocol.
Although you can establish an SSH connection to the unit without the public key, 
the public key provides validation for the Outlet Managed PDU, and once this key 
is supplied to the SSH client, the client will no longer display a warning indicating 
that the Outlet Managed PDU is not a recognized user when the client attempts to 
establish a connection.
The /K command uses the following format:
/K <k>  [Enter]
Where 
k is an argument that determines which type of public key will be displayed, 
and the k argument offers the following options:
1.  SSH1
2.  SSH2 RSA
3.  SSH2 DSA
For example, to obtain the public SSH key for an SSH2 RSA client, type 
/K 2 and 
then press [Enter].  Note that when capturing the SSH key, you can either configure 
your terminal application to receive the parameter file, or simply copy and paste the 
resulting SSH key.
Notes:
•  Although the Outlet Managed PDU does not support SSH1, the /K 
1 command will still return a key for SSH1.
•  When capturing the SSH key, you can either configure your 
terminal application to receive the parameter file, or simply copy 
and paste the resulting key
