horizontal rack PDU
Also known as “horizontal PDUs,” Rackmount PDUs mount horizontally within the rack like other IT equipment. Typically, they are 19 inches wide, take up one or two rack spaces (1U or 2U), and have 6 to 16 outlets. Newer horizontal rack PDUs offer many of the same features as their vertical PDU cousins.
Here are the key points about YOSUN horizontal rack mount PDUs (Power Distribution Units):
6 assembly lines, assembling 30,000 pieces per month. Laser cutting workshop, cutting 50,000 pieces of aluminum alloy per day. Our factory has 8 injection molding machines, producing 70,000 pieces per day.
Quality control strictly according to ISO9001. Quality has always been paramount at YOSUN. Our PDU have Qualifed to GS, CE, VDE, ULBS, CB, ROHS,CCC certifications, assuring customers that the products they receive are safe, reliable, and made of the highest quality.
YOSUN provides competitive pricing without compromising on quality. Their PDUs are not only affordable but also offer features typically found in higher-end models, making them a cost-effective choice for businesses looking to enhance their power distribution systems.
Many horizontal rack PDUs are designed to operate at lower temperatures, which means they have to be cooled like IT equipment. Horizontal rack PDUs can be a good choice for lower power loads or in conjunction with in-row UPS equipment. If there’s limited space in the back of the cabinet for cable management, it may make sense to install the PDU horizontally.
While vertical PDUs have become the norm in modern data centers, horizontal rack PDUs still have their place when optimizing space, managing airflow, or distributing power from an in-rack UPS. The right PDU solution depends on the specific requirements and constraints of each data center.
Maintaining horizontal Power Distribution Units (PDUs) effectively is crucial for ensuring reliability and minimizing downtime in data center environments. Here are some best practices for maintaining horizontal rack PDUs:
1. Regular Monitoring and Inspection
Temperature Checks: Regularly monitor the temperature around the PDU to prevent overheating. Ensure that the cooling systems are functioning properly and that airflow is not obstructed by cables or equipment.
Load Monitoring: Use PDUs with metering capabilities to track power consumption. This helps in identifying potential overloads and balancing loads across outlets.
2. Cable Management
Organized Cabling: Implement effective cable management strategies to prevent tangled or obstructive cables. Use cable ties, trays, or management arms to keep cables neat and out of airflow paths.
Avoid Overcrowding: Ensure that the PDU is not overloaded with too many devices, which can lead to overheating and potential failures.
3. Scheduled Maintenance
Routine Checks: Schedule regular maintenance checks to inspect the PDU for any signs of wear, damage, or malfunction. This includes checking connections, outlet functionality, and physical integrity.
Firmware Updates: If applicable, keep the firmware of smart PDUs updated to ensure optimal performance and security.
4. Environmental Controls
Humidity Monitoring: Monitor humidity levels in the rack environment as high humidity can lead to equipment damage. Use environmental sensors if available.
Airflow Management: Ensure that there is adequate airflow around the PDU. Consider using blanking panels in unused rack spaces to direct airflow effectively.
5. Use of Advanced Features
Switched PDUs: Consider using switched PDUs that allow for remote management of individual outlets. This enables quick power cycling of devices without needing physical access, reducing downtime during troubleshooting.
Alerts and Notifications: Utilize PDUs with alert systems that notify administrators of potential issues like overloads or temperature spikes, allowing for proactive management.
6. Documentation and Labeling
Clear Labeling: Label all outlets clearly to avoid confusion during maintenance or troubleshooting. This helps in quickly identifying which devices are connected to which outlets.
Maintain Documentation: Keep detailed records of power loads, maintenance activities, and any incidents related to the PDU for future reference and analysis.
7. Training and Awareness
Staff Training: Ensure that all staff involved in data center operations are trained on the proper use and maintenance of horizontal rack PDUs to minimize human error during operations.
Ensure that the PDU is properly connected to a functioning power outlet. Verify that the circuit breakers for the PDU inputs are not tripped at the building's electrical panel.
For PDUs rated at 30A and above, check the individual bank breakers. If any have tripped, reset them to restore power to the affected outlets.
LED Indicators: Check the LED indicators near each outlet. A green light indicates that the outlet is enabled and supplying power; if it's off, the outlet may have been disabled via a network command or due to a fault. Web Interface Control: Access the PDU's web interface to check if any outlets are configured to remain off. You can enable them again through this interface.
Use a multimeter to check for voltage at the outlets. Measure between Line, Ground, and Neutral to confirm there is proper voltage present.
If an outlet LED is on but no power is present, there may be an internal failure (e.g., an open relay). Restarting the PDU can sometimes resolve this issue.
If your PDU supports hot-swapping (like some Eaton models), you can replace components without shutting down the entire system, which helps in maintaining uptime during troubleshooting.
Look into any specific configurations that may have been set up for the PDU, such as power sequencing or outlet control settings, which might affect power distribution.
If all else fails and power issues persist after following these steps, reach out to the manufacturer’s support team for further assistance.
