11Automatic 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
Switches 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 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. See the User Guide online 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.
