Introduction
Regular inspections of Power Distribution Units (PDUs) are critical for ensuring uninterrupted power delivery and preventing downtime in data center environments. This comprehensive checklist helps IT and facility managers identify potential issues before they lead to power failures, electrical hazards, or equipment damage. A thorough inspection not only ensures operational reliability but also maximizes energy efficiency and extends the service life of both PDUs and connected equipment.
Following this server power strip (PDU) inspection checklist as part of your routine data center maintenance helps create a more resilient IT infrastructure, prevents costly outages, and provides valuable documentation for compliance and capacity planning. The checklist aligns with industry standards, manufacturer recommendations, and best practices for data center power management and electrical safety.
PDU Information
Pro Tips for Effective PDU Management
- Load Balancing: Distribute equipment power connections evenly across multiple PDUs and circuits to prevent overloading and ensure redundancy in case of PDU failure.
- Cable Management: Maintain proper cable routing and organization to prevent stress on power cords, ensure adequate airflow, and facilitate visual inspections of connections.
- Environmental Monitoring: For intelligent PDUs, utilize environmental monitoring capabilities to track temperature and humidity near critical equipment, providing early warning of potential cooling issues.

Detailed Inspection Procedures
Follow these structured procedures to ensure a thorough inspection of server power strips (PDUs). Adapt these steps to your specific PDU model and data center requirements.
Visual Inspection Procedure
- Ensure proper PPE is worn if working with live equipment
- Use flashlight to inspect all areas of the PDU
- Check for discoloration that indicates overheating
- Inspect all outlets and connections for burn marks
- Document any physical damage with photos if possible
Load Testing Procedure
- Record current load readings from display or monitoring system
- Compare with rated capacity to ensure below 80% threshold
- For metered PDUs, verify individual outlet loads
- Check for phase balance on three-phase PDUs
- Document historical load trends for capacity planning
Thermal Assessment
- Use infrared thermometer to check for hot spots
- Record temperature at input connection point
- Measure temperature at heavily loaded outlets
- Verify temperature at circuit breakers/fuses
- Compare readings with previous inspection data
Connectivity Verification
- Test network connectivity for intelligent PDUs
- Verify SNMP or other monitoring protocols functioning
- Check that alerts and notifications are properly configured
- Update firmware if required (during maintenance window)
- Confirm remote management capabilities operational
