Network Management Card: How to Access a Configured Unit

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 NetworkAIR IR In-row Precision Air Conditioner’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.

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 Network Management Card. The default read community name is public; the default read/write community name is private.

If you enable SSL and SSH for their high-security authentication and encryption, disable SNMP. Allowing SNMP access to the Network Management Card compromises the high security you implement by choosing SSL and SSH. To disable

Note SNMP, you must be an Administrator; use the SNMP option of the Network menu.
