6.5 Configuring the Power Distribution Units

The power distribution units (PDUs) are configured with a static IP address to connect to the network for monitoring.

Ensure you have the following before connecting the PDU to the network:

• Static IP address
• Subnet mask
• Default gateway
• Ethernet cables
• Laptop computer with either Oracle Solaris or Microsoft Windows

For systems less than full racks, the PDU Ethernet connections may use available ports in the Management Network Switch. Note that for full rack systems, you cannot connect PDUs to the Management Network Switch because all the ports on the switch are already reserved for other components.

The following procedure describes how to configure and connect the PDU to the network:

1. Power off the PDU.

2. Disconnect the power leads from the power source.

3. Select an unused LAN network connection from the available network connections on the laptop as follows:

   • For Oracle Solaris:

     1. Log in as a super user.

     2. Use the dladm show-link command to find an unused Ethernet interface.

     3. Use the ifconfig -a command to determine which interface is being used.

     4. Use the following command to plumb the unused interface:

        # ifconfig interface plumb up
        

        In the preceding command, interface is the network interface determined in step 3.c.

     5. Using the following command to assign an IPv4 address and netmask to the interface:

        # ifconfig interface IPv4_address netmask + netmask \
          broadcast broadcast up
        

        In the preceding command, interface is the network interface, IPv4_address is the IP address, netmask is the netmask address, and broadcast is the broadcast address.

        Note:

        The network interfaces configured with the ifconfig command do not persist across system restarts.

   • For Microsoft Windows:

     1. Select Settings from the Start menu.

     2. Select Network Connections from the Settings menu.

     3. Select an unused local area connection from the Network Connections menu.

     4. Double-click Internet Protocol (TCP/IP) in the Local Area Connection Properties window. The Internet Protocol (TCP/IP) window appears.

     5. Select Use the following IP address.

     6. Enter the IP address in the IP address field. Do not use 192.168.0.1 because that is the default PDU metering unit address.

     7. Enter the IP address in the Subnet mask field.

     8. Leave the Default gateway field blank.

     9. Click OK.

4. Connect the PDU and the laptop to two ports on the Management Network Switch. The equipment currently using the Management Network Switch must be disconnected temporarily.

5. Connect the PDU power input lead to the power source. Only one PDU power input lead needs to be connected, as follows:

   • On PDUs with one power input lead, connect the one lead to the power source.

   • On PDUs with two power leads, connect the first power lead to the power source. The first power lead is labeled 0.

   • On PDUs with three power input leads, connect the middle power lead to the power source. The middle power lead is labeled 1.

6. Use a Web browser to access the PDU metering unit by entering the factory default IP address for the unit, 192.168.0.1, in the address line of the browser. The Current Measurement page should appear.

7. Click Network Configuration in the upper left of the page.

8. Log in as the admin user on the PDU metering unit. Change the password after configuring the network.

9. Confirm the DHCP Enable check box is not selected.

10. Enter the following network settings for the PDU metering unit:

    • IP address
    • Subnet mask address
    • Default gateway

11. Click Submit to set the network settings, and reset the PDU metering unit.

12. Disconnect the PDU and laptop from the Management Network Switch.

13. Reconnect the two cables that were originally connected to the Management Network Switch.

14. Connect an Ethernet cable to the PDU metering unit RJ-45 Ethernet port and to the network.

15. Log in to the PDU metering unit using a Web browser. Use the PDU metering unit's static IP address in the browser's address line. If the configuration was successful, then the Current Measurement page is displayed.

16. Connect the remaining PDU power input leads to the power source.
