Dell ITA can monitor power usage on many of the Dell PowerEdge servers. In order for this functionality to work, the servers must have power supplies that implement the PMBus specification. Generally this means the newest Dell PowerEdge Servers available today.

While all Dell servers on sale today support it, the PMBus specification is not supported by all older Dell servers. Below is a chart that shows which older servers can be monitored for power usage.

Power Supply options for 1950 III and 2950 III Models

When ordering these systems you have several options for Power Supplies. In the US, the default configuration includes the "Energy Smart" power supplies that are capable of power monitoring. If you change the configuration to the "Redundant Power Supply" option, these are NOT capable of power monitoring.
