5 Tips for Choosing and Managing Data Center Power Cords

Power Cords can make or break your electric system. Hence, choosing the right cord is inevitable. There are various things you must keep in mind before you purchase the power cords for your data center in order to avoid any failures later on. Let us have a look at them one by one.

Know the Equipment You Will Be Using

The data center requires routers, switches, modems, and many other IT equipment along with security cameras and cooling systems. It is possible that not all this equipment will require the same power cords. Attaching a wrong power cord can damage the equipment. To avoid such scenarios knowing the equipment's maximum power voltage and type of connector is essential.

Different countries use different connector types, so if you have equipment imported from another country ensure the voltage and type beforehand. The other thing you will need is connectors. There are various types of connectors available in the market like c13 power connector, c15, c19 and many more. You can also keep a universal power cord handy in case any cord fails. This will help you resume the services quickly. One more thing to keep in mind is to ensure that you should not choose the cord that exceeds equipment maximum power voltage.

Organizing the Cords

We all know wires can make a mess. Data centers have hundreds of wires running here and there. And there is a high possibility of them getting tangled. It can get even worse if all the cords are the same color. In such situations locating a disconnected cord can be a challenge. You can save time and effort by color coding the wires based on their density and label them. Having these two things on the cord will quickly give you the idea of where it is coming from. You can also include detailed information on the label like its length, capacity, the name and number of the equipment, location of the equipment etc.

Length and Gauge of the Cord

The load capacity of the cord depends on its length and the gauge. Generally, as the length of the cord increases, the capacity to deliver the power decreases. So, for equipment with high load capacity, ensure the length of the cord is short, to prevent it from overheating the cord. The gauge defines the cords capacity to transmit the current. The low value of the gauge indicates higher capacity of the cord. For example, 8 AWG (American Wire Gauge) cords can carry more current and are thicker compared to 14 AWG cords.

De-Rating Approach

The cable load will be on for hours or say forever at your data centers. It is obvious that when current passes through the cords, chances of them overheating increases. The National Electric Code (NEC) suggests that the size of the wire and the amperage must be lower or de-rated for the equipment with continuous application. For instance, if the cable has 100 amps rating then it is advisable to run them at 80 amps or below. Thus, these are best practices to avoid overheating, fires or shortages of the cord.

Use Angled Connectors

As there are a lot of high density cables in the data center, it is highly possible that racks get overcrowded. Such conditions can lead to overheating of the cables. However, angled connectors can help organize them. They have different options like left, right, up, down and 45 degree angle connections. These connectors help in creating the space between the cables for air flow and helps in cooling the servers. This connector also helps in reducing the chances of disconnecting the incorrect cord. Thus, organizing it well will ensure your services are not disrupted.

Conclusion

Choosing the right cord for your equipment will ensure its safety whereas managing the cords properly will ensure the cords longer shelf life. It will also reduce chances of disconnecting the wrong cord and also connecting the right cord during failure of the equipment or the cord. Last two important things to remember is that keep the universal power cord handy in case any cord fails and use the right connectors like c13 power connector, c15, or c19 according to the type of the cord.

Power Splitter vs. Extension Cord: Which One Is Right for You

Power distribution is a crucial aspect of managing electrical devices efficiently. When faced with the need to connect multiple devices to a single power source, two popular options come to mind: power splitters and extension cords. Understanding the differences between these two solutions is essential to ensuring optimal power management and safety. In this article, we will explore the features, applications, and considerations associated with power cord splitters and extension cords, helping you make an informed decision on which one is right for your specific needs. Power Splitters: Unleashing Versatility Power splitters, also known as cord splitters or power cable splitters, are designed to divide a single power source into multiple outlets. These devices allow you to connect several devices simultaneously, expanding the number of electrical connections available. Power cord splitters come in various configurations, including three-way, four-way, and even more complex mode

How to Connect Tablet to External Monitor or Flat-screen TV Using Computer Adapters?

Tablets have numerous use cases. They have brought a radical change in the user experiences with larger display as compared to smartphones. You can enjoy videos and movies more on tablets as compared to smartphones. But, what if you are craving for a bigger screen? What if you want to view videos or movies on a screen that is larger than a tablet? Well, grab your popcorn and tie your seatbelts as you can enhance the multimedia experience by connecting tablet to an external monitor or a flat-screen TV. Watch movies the way you watch them in theatre. And what gives you a better viewing experience? Computer adapters . Here is a brief yet step-by-step guide to enable you to connect tablet to a larger screen: Check Your Tablet’s Ports Firstly, take a close look at the tablet’s ports. It is necessary because the ports of the tablets have started advancing with every passing year. Traditionally, tablets had just video ports. Now, the new tablets have USB-C or USB Type-C ports. Many

Fiber Optic Cables Vs Ethernet Cables: What Is the Difference?

Wi-Fi is like love. Always in the air and ready to connect you with the fascinating digital world. But ever wondered what keeps it in the air? Well, just like any relationship has a foundation of understanding, a wireless network has a fiber cabling underneath that helps people to connect with the internet anytime they want to. The other most popularly used cable type is Ethernet cables. They are used everywhere right from IP camera technologies to LED lighting. These cables are quite cheaper as compared to fiber cables; but when one wants to have a huge and powerful network cable , fiber cables become necessary. Both the cables have their advantages and disadvantages, specialties, and limitations. Through this blog, we will differentiate between the two and try to understand both in details: History of Fiber & Ethernet Cables The fiber optic technology was first used in 1969 when NASA sent it to the moon for use in television cameras. And a company named Xerox developed Eth
