Tips to Choose and Manage Data Center Power Cords

Usually, in data center power system design, more emphasis is given on power equipment and not on power cords. The right selection of power cords not only matters to the cost of the data center installation but also to its performance. Using good quality and the right type of power cords is of utmost importance.

Generally, for the data center the, C13 power cords, C15 power cord, and C19 power cord are popular for their use. For more tips and information regarding how to manage data center power cords, keep reading!

Know the Equipment

The first thing we need to figure out is the maximum power voltage for the equipment. For connecting multiple devices, calculate the total power and then choose the connecting plugs. The next thing on the list is the connector type of the equipment to determine the power type.

For different countries, the standards for connectors of powered equipment and power cords are different. So, different types of connectors have different specifications. Like the international standard IEC, NEMA, Schuko/CEE7,BS1363 UK, etc. Among these, the IEC power cords and the NEMA power cords are suitable for the data centers.

The most common IEC outlet type in data centers are the C14 to C13 power cord, C14 to C15 power cables, and C20 to C19 power cord cables and the most common NEMA power connectors are NEMA 5-15P.

Colored Cords for Easier Management

As you know you will be dealing with lots of cables, different colored cords are suggested to organize and maintain high-density cables easily. Colors provide quick visual identification. To simplify cable management, it is better to have different colors for power cords.

For example, you can differentiate side A cords from side B power cords to identify and organize dual power feeds for redundant power sources. Similarly, for data cables, you can color code to identify roles or functions of the cable or the type of connection.

You can also label the cables. This way your data center manager will save a lot of time spent tracing your data center cables or unexpected disconnections while moving equipment from one place to another.

Calculate Cord Gauge and Length

The extension cord’s load capacity i.e. the ability to carry current is determined by the cord gauge and the length. What is a cord gauge? The cord gauge is the size of the wire based on its cross-sectional area. In the US, the method of notation is American Wire Gauge(AWG). A lower AWG number means the wire size is large and the capacity of the cord is also high.

For example, 14 AWG power cords are thicker and able to carry more current compared to 16 AWG power cords. Using a thicker cord is a wise decision keeping in mind the future of your data center.

On the other hand, for cable length, the shorter the power cord, the less the power loss. Power extension cords are 2 feet to 30 feet or even longer in length. But it should not exceed 100 feet to prevent power loss and overheating. So as length increases, the power cord will deliver less power to the connected devices.

Thus, while using high amperage ratings, it is better to use the power cord with less length. In order to cover a longer distance, you must upsize the power cord.

Angled Connectors to Save Space

To save space and improve airflow to servers, you can use angled connectors. There are various options like up, down, right, left, and 45° angle options are available for connections within high-density racks. With proper organization, you won’t have to disconnect the power cord when working in a high-density space.

Conclusion

Cable management does not have to be complicated. With the right information and guidance, you can go a long way. We hope you will find these data center power cords management tips helpful. We assure it will significantly contribute to the continuous uptime of your data center.
