Telnet and SSH

You can access the control console through Telnet or Secure SHell (SSH), depending on which is enabled. Select the Administration tab, the Network option on the top menu bar, and then the access option under Console on the left navigation 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 a Main Module’s control console:

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

telnet address

As address, use the Main Module’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 User).

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 Environmental Manager: Main Module User’s Guide for more information on configuring and using SSH.

Simple Network Management Protocol (SNMP)

SNMPv1 only. After you add the PowerNet® MIB to a standard SNMP MIB browser, you can use that browser to access the Main Module. All user names, passwords, and community names for SNMP are transferred over the network as plain text. The default read community name is public; the default read/write community name is private.

SNMPv3 only. For SNMP GETs, SETs, and trap receivers, SNMPv3 uses a system of user profiles to identify users. An SNMPv3 user must have a user profile assigned in the MIB software program to perform GETs and SETs, browse the MIB, and receive traps. The default settings are no authentication and no privacy.
