How to Access the Automatic Transfer Switch Interfaces
12 Automatic Transfer Switch - Installation and Quick Start
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. If you use the high security of SSL for the Web interface, use
Secure SHell (SSH) for access to the control console. SSH encrypts user names, passwords, and
transmitted data.
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.
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.

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