How to install Raritan Dominion PX2-2901U 48-Outlets PDU

• Prepare your rack by ensuring there is adequate space for heat dissipation and that the mounting area is clean and free of obstructions. Verify that the rack is rated for the weight and plan cabling paths to minimize tension on power cords.
• Mount the PX2-2901U securely in a standard 19" rack using the appropriate mounting ears or rails supplied with the unit. Confirm that the alignment allows convenient access to outlets and the management port.
• Connect the PDU to a suitable AC power source that matches the product’s input voltage specification (100–240 VAC). Use a properly rated power cord and follow local electrical codes for safe installation. Do not exceed the specified input current.
• Connect the PDU to your network for remote management by plugging an Ethernet cable into the management port and linking to your data center network or DCIM system. Ensure IP addressing is configured as per your environment (static or DHCP as supported).
• Power up the PDU, access the web interface or management console, and perform initial configuration. Label outlets, set up alerts and thresholds, and verify that monitoring data is streaming correctly. Run a quick dry-run by loading non-critical equipment to confirm accurate readings and alerting behavior.
