4.3 Network Configuration
Aggregation is enabled on the master rPDUs only. As each master can support up to 49 downstream
devices, the number of masters depends on the overall size of the installation and the preferred network
architecture.
The master rPDU must be commissioned before it's connected to the primary management network or to
the downstream device network. This commissioning is typically accomplished via a laptop or local
machine connected directly to port 1 on the IMD.
After local connectivity is established, you can commission the master rPDU.
To commission the master rPDU:
1.
Use the top drop-down menu to navigate to System - Locale.
2. Select the appropriate Default Language and Temperature Units from the drop-down menus.
These settings are pushed to the downstream devices in its network.
3. Browse to System - Utilities. Change the settings as desired.
a. Aggregation: Choose Enabled from the drop-down menu.
b. Managed Device Username: Defines the username configured on all downstream devices.
c. Managed Device Password: Defines the password configured on all downstream devices.
4. Enter the new password, verify the password and click OK.
5. Click Submit. If Aggregation is enabled, the Device tab appears next to the Sensors tab on the
top navigation bar.
After aggregation is enabled on the master rPDU, configure the remaining master rPDU settings. Connect
the master rPDU to management network (port 1) on the IMD and the device network (port 2).
NOTE: The master rPDU has a built-in DHCP network to assign addresses to its downstream devices.
This DHCP network uses 192.168.124.0/24 addresses and they cannot be used for the management
network.
4.3.1 Downstream Devices
In the initial release of aggregation, downstream devices are defined as rPDUs within the GU1 and GU2
product platforms as well as GXT4 UPS. All GU1 rPDUs must be running firmware version 3.3.3 or later; GU2
rPDUs must be running version 5.3.0 or later. If the rPDUs are newly-ordered and have never been
configured with network settings, they are ready for aggregation out-of-the-box. If the rPDUs have been
deployed in a computing environment and commissioned with local LAN settings and user accounts, the
rPDUs must be reset to factory defaults. The master rPDU then pushes configuration data to the
downstream devices, including:
•
Network settings
•
Default Language and Temperature Units
•
Username
