How to Access the Automatic Transfer Switch Interfaces

Telnet/SSH

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 an Automatic Transfer Switch’s control console from any computer on the same subnet:

1. At a command prompt, use the following command line, and press ENTER:

telnet address

As address, use the Network Management Card’s IP address or DNS name (if configured).

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. Secure SHell (SSH) for access to transmitted data.

If you use the high security of SSL for the Web interface, use the control console. SSH encrypts user names, passwords, and

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.

See the User’s Guide for more information on configuring and using SSH.

SNMP

After you add the PowerNet MIB to a standard SNMP MIB browser, you can use that browser for SNMP access to the Automatic Transfer Switch. The default read community name is public; the default read/write community name is private.

Note

If you enable SSL and SSH for their high-security authentication and encryption, disable SNMP. Allowing SNMP access to the Automatic Transfer Switch compromises the high security you implement by choosing SSL and SSH. To disable SNMP, you must be an Administrator; use the SNMP option of the Network menu.
