Cannot connect using 

Secure Shell

• If you cannot connect using SSH, you may have exceeded 

the maximum number of concurrent Telnet/SSH sessions 
permitted. Try connecting again at a later time. 

• Be sure the control parameters for the SSH server are 

properly configured on the switch, and that the SSH client 
software is properly configured on the management station.

• Be sure you have generated a public key on the switch, and 

exported this key to the SSH client.

• Be sure you have set up an account on the switch for each 

SSH user, including user name, authentication level, and 
password.

• Be sure you have imported the client’s public key to the 

switch (if public key authentication is used).

pin-out connections provided in the Installation Guide.
