You can monitor how much current the equipment connected to the PDU uses by either checking the PDU’s LCD screen or by viewing the Current Measurement page using the HTML interface.
You might need to open the rack’s rear door to access the PDU.
You can find the metering unit in the middle of the PDU.
The LCD screen displays the amp measurements of all of the phases of a single PDU module (see Relationship Between Modules and Outlet Groups for a description of PDU modules).

3 Abbreviation for amperes (amps)
4 Metering unit phase number
Using the metering unit’s HTML interface, you can monitor the current being used by attached equipment. You can also see how these current readings relate to the threshold parameters you set in Setting Threshold Parameter Levels.
See Accessing a Metering Unit on the Network. After accessing the PDU, the Current Measurement page displays.
Current Measurement Page shows an example Current Measurement page for a 37 kVA PDU, which has three modules with three phases each. (See Relationship Between Modules and Outlet Groups for a description of PDU modules.)

4 Number of amps of current being used per phase
If you set threshold parameter values (see Setting Threshold Parameter Levels), the module graph and current amp number are displayed in different colors, depending on how much current the attached equipment is using. See the following table for a description of these colors.
Note - If you do not set any threshold parameter values, all of the measurements are displayed in red.
Caution - If the PDU is out of balance, the PDU and the attached equipment might heat up and cause serious damage to the equipment, PDU, and the rack. Power off the equipment and the PDU immediately.
