In this section, we will discuss details regarding the PDU ports.
PDU ports can be connected to a device, an asset (such as modem), or another PDU.
The type of connection is set in the Content Type pulldown.
The Object id is id of the content type (Device, Asset or PDU) object.
To set the id, click on the lookup icon. You will then see a list of existing object of the selected content type and you should select the device, asset or pdu that connects to this port.
Port name: The Port name or # on the PDU.
Object PSU label: The label of the power supply on the device/asset side.
Object name: This is automatically created (after you click save), based on the content type and object id and gives you a link to the device, asset or pdu connected to that port.
Port view from the other side
In the device view, the Other tab shows the PDU port connectivity for the device.
From the Physical Device Edit screen, you can only change the PSU object label. Any other editing has to be done from the PDU edit page.
Available ports in PDUs
The List view for the PDUs also shows how many ports are available.
Power per PDU port
Starting in v316, we have added a new field named Watts for PDU port power estimations. Be default, the watts value will be the device hardware watts value (if a device is connected to that port) or PDU total watts (if a PDU is connected to that port). You can enter any value to override the default.
If there is no default value (e.g. an asset connected to a PDU port would not have default power value), you can use this field to manually enter the value.
Overridden and default values will be used by device42 to estimate the total power for that PDU. The sum is visible on all the PDU pages (list, view and change page).
The PDU watts sum will also be visible on the rack layout page as shown below.
