How to Access the ATS Network Management Interface

Telnet and 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 ATS’s control console from any computer on the same subnet:

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

For address, use the ATS’s IP address or DNS name (if configured).

2.Enter the user name and password (the defaults are apc and apc for an Administrator, and device and apc for a Device Manager).

SSH for high-security access. If choosing the high security of SSL for the Web interface, use Secure SHell (SSH) to access the control console. SSH encrypts user names, passwords, and transmitted data.

The interface, user accounts, and user access rights are the same when accessing the control console through either SSH or Telnet. In order to use SSH, you must have an SSH client program installed on your computer and SSH must be properly configured.

Refer to the InfraStruXure Power Generation System’s on-line Network Management User’s Guide for more information about configuring and using SSH.

SNMP

After adding the PowerNet MIB to a standard SNMP MIB browser, you can use that browser for SNMP access to the ATS. 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 ATS compromises the high security implemented by choosing SSL and SSH. To disable SNMP, you must be an Administrator; use the SNMP option from the Network menu.
