How to Install Eaton Metered Input PDU

• Plan and prepare: Assess rack space and determine the optimal mounting location within the 19-inch rack. Ensure you have access to a three-phase power source that matches the L21-30P input requirements and provides a secure, stable supply for the 24A rating.
• Power down equipment: Before installation, power down all devices connected to the rack and verify that main power to the rack is safely disabled to avoid any risk during mounting and cabling.
• Mount the PDU: Slide the 0U metered PDU into the rack rails and secure it according to your rack hardware guidelines. Ensure the unit is level and firmly anchored to handle the weight of connected cabling and equipment.
• Connect the input power: Attach the L21-30P plug to a compatible three-phase power outlet using properly rated cables. Verify connections are secure and that the power source is stable before energizing the PDU.
• Route and label outlets: Systematically connect IT gear to the 24 outlets (5-20R). Use color-coded outlet sections to map devices to specific outlets, improving readability and cable management for future maintenance.
• Configure metering and monitoring: Use the PDU’s interface or your DCIM system to enable metering, configure alert thresholds, and set up data readouts. Ensure you can access energy data for each outlet and the entire rack for ongoing visibility and chargeback accuracy.
• Test and verify: Power on the rack, confirm that all devices initialize correctly, and verify that the monitoring interface reports accurate readings. Run a short load test to confirm stable operation and data accuracy across outlets.

Frequently asked questions

• What is a metered input rack PDU? A metered input rack PDU is a power distribution unit designed to provide utility-grade energy metering for the entire rack and, in many cases, per-outlet monitoring.
