APC: External Power Controllers

Intended for use with Cassatt Active Response Standard Edition, Premium Edition and Data Center Edition V5.1.

This article describes how to configure the APC external power controller for management by Cassatt Active Response.

Configure the power controller

Follow these steps to configure an APC external power controller. The example shown is for the APC 7900/7901; other models may vary.

1. Access the external power controller using telnet or the serial port.
2. Use the following table to configure network access and authentication for the power controller.
   

   The following settings reflect using a static IP address with DHCP disabled. You can, however, configure the external power controller to DHCP if the device is in a network outside of Cassatt Active Response control. In this case, make sure that you note the IP address to use when adding the power controller to the Cassatt Active Response Controller.

   APC 7900/7901	Example and notes
   Configure and enable SNMP	Navigate to: Network > SNMP > SNMPv3 Specific Settings Select an SNMPv3 User Profile that is not in use. NOTE: The SNMPv3 user profile and authentication phrase are not the same as the external power controller username and password. Configure the authentication: a) User Profile b) Authentication Phrase c) Set Access Type to Auth/No Priv for one of the existing profiles. NOTE: If you don't know the hidden authentication phrase, configure one and make a note of it; you'll need to enter the same phrase in the Controller when creating the external power controller. NOTE: If you are changing an existing authentication phrase, be aware that some external power controllers can take several minutes before changes take affect. This is an issue with the external power controller and not Cassatt Active Response. Accept changes and verify success. Go back to the SNMPv3 Specific Settings menu and open the counterpart SNMPv3 Access Control file that corresponds to the SNMPv3 User Profile number you configured in step 2. (For example, if you created SNMPv3 User Profile 2, you must configure its counterpart, SNMPv3 Access Control 2 file.) In the SNMPv3 Access Control file, set Access to Enabled. Accept changes and verify success. Navigate to: Network > SNMP > Settings. Make sure SNMPv3 Access is set to Enabled. Accept changes and verify success.
   Configure network access	Navigate to: Network > TCP/IP. Edit to reflect the static IP address: System IP, Subnet Mask, and Default Gateway.

Where to go next

The power controller is now ready to add to the Cassatt Active Response Controller using the wizard at: Discovered Pool > Power Controllers > New Multi-Node Power Controller. If you need help in gathering required information for the wizard, see your appropriate task map:

• For power only nodes: Power Only Nodes: Configuration and Management
• For utility computing nodes: Task Map: Getting Hardware Under Cassatt Active Response Management
