WHY LABEL YOUR INSTALLATIONS?
Have you ever visited an installation and found yourself unable to identify the installed equipment ports and connections? The wires and cable runs make no sense and you cannot figure out where one is going. Things become more confusing if there has been some time-lapse.
Most field engineers have encountered this predicament at some time!
What is the root cause of all of these? You guessed correctly! There was no proper labelling. After completing the installation, the installer failed to label.
Labelling your installation simplifies troubleshooting, repairs, and upkeep.
Labelling is regarded as an essential component of every installation. It allows for quicker identification of installed equipment, ports on the equipment, and cable runs.


WHAT ADVANTAGES DO YOU GET FROM LABELLING YOUR INSTALLATION?
Ease of maintenance: Maintenance becomes a breeze when precise and comprehensive labelling is done. Appropriate labeling is critical for the efficient operation of any electrical or telecommunications infrastructure or Data Centre.
Efficiency: The field engineer's efficiency improves when equipment, ports, connectors, and cables are identified more easily. Working in such an equipment room is always a delight. Efficiency skyrockets!
Reliability: A well-labelled installation has a high level of dependability. You always know where your equipment, ports, and cables are going and where they are coming from. The likelihood of incorrect connections and cable identification is greatly decreased.
Profitability: Bottom line! Time is money. Correct labelling saves downtime and maintenance costs. Maintenance visits are less taxing. All of these put more money in your pocket.

What is a Locking PDU Socket Is the focus of this tutorial. We are looking at what is referred to as Locking PDU Sockets. Because of their reliability, they are usually used in high-end PDUs.
The Locking PDU Sockets incorporate a locking mechanism between the equipment plug and the PDU socket thereby securing the physical connection. Pushing the red button releases the plug from the socket. This ensures the plugs cannot be accidentally pulled out of the socket.
There is also the P-Lock system which is more widely used in the USA. P-Locks are designed with locking clips on the sides of the connector keeping them firmly plugged in.
The Locking PDU Socket is available mainly for the commonly used plugs and sockets in the IT industry - the IEC C13/C14 and C19/C20.
There are other options available in the market ranging from plug retention to locking mechanisms.
This tutorial concludes our 9-Part series on PDUs. We hope you have acquired more knowledge of PDUs and their terminologies. If you missed any tutorial or want to learn more, visit: https://www.numeriquelimited.com/blog

Our tutorials on PDUs continue in this tutorial with the treatment of Horizontal versus Vertical PDUs.
PDUs are mounted either horizontally or vertically depending on the length of the PDU. The length is determined by the number of ways, the accessories on it, and the type of sockets. When the PDU length is more than the standard 19” rack length, the horizontal installation is abandoned for the vertical.
For the British Standard 13A socket or the Universal socket, the maximum number of sockets that will fit on a 19" rack is between 6 – 8 sockets (or ways), without accessories. Whereas the IEC C13 socket can accommodate 10-12 Ways, without accessories on the same 19" Rack.
Hence, vertically mounted PDUs are referred to as Vertical PDUs as opposed to horizontally mounted PDUs.
Remember from the last tutorial (Part 7) that Vertical PDUs are also referred to as 0U (ZERO U) PDUs.

1U, 1½U, 2U, or 0U (Zero U) PDU are terminologies used to describe PDUs. What do these terminologies mean? This tutorial will explain why and which PDUs are described like this.
The "U" is the rack size unit "U" which is the universally accepted standard height of equipment to be mounted in a rack (or cabinet). The rack (or cabinet) is used for mounting equipment in a Data Centre, Server Room, or Telecoms equipment room.
1U rack size is 1.75 inches or 4.445cm. So, a 1U PDU is a PDU that has a height of 1U or 1.75 inches and will occupy a horizontal 1U space in the rack. Ditto for the spaces occupied by the 1½U (2.625 inches tall) and 2U (3.5 inches tall) PDUs. The PDU is described, in this case, with the horizontal space it occupies in the equipment rack.
Now, what of the 0U (ZERO U)? The 0U occupies no rack size space because it is mounted vertically. All vertically mounted PDUs are described as 0U.
We will treat horizontal and vertical mounting of PDUs in another Tutorial.

We had been discussing the PDU unit as a whole but there is a part of the PDU we need to know more about - the PDU Sockets where you plug your equipment.
Different countries have different types of sockets. The IEC (International Electrotechnical Commission) has also published a range of PDU Socket specifications. We will be showing you the more popular PDU Sockets here.
With NEXION PDUs, you can mix and match your PDU sockets as you like, on any type of PDU except Intelligent PDUs which are pre-configured with IEC C13 and C19 PDU Sockets.

In this tutorial, we are discussing the AUTOMATIC TRANSFER SWITCH or ONLINE PDU.
In Parts One to Four of our PDU Tutorial Series, we defined the different types of PDU based on the “output” of the PDU. In this tutorial, the AUTOMATIC TRANSFER SWITCH (ATS) or ONLINE PDU is defined by the functions available at the “input” side of the PDU.
The ATS or ONLINE PDU has two different and distinct input sources and can automatically switch between the two sources with no interruption to provide power for the PDU. If, for example, your primary source is an inverter and it fails or requires maintenance, the ATS OR ONLINE PDU allows a seamless switchover to a secondary source (e.g. a generator or utility mains). The power supply to the PDU is not interrupted in the process.
This arrangement is not negotiable for sensitive Server Rooms or Data Centers.
If the transfer switching is done manually, then you have a Manual Transfer Switch.
For the output side, you can still have all the features of a Basic PDU, or a Switched, Monitored/Metered, or Intelligent PDU depending on the manufacturer’s configuration. In nearly all cases, the ATS or ONLINE PDU comes as an Intelligent PDU.

PDUs –KNOW MORE! (PART THREE)[/center]
So far we have discussed Basic and Switched PDUs. Today we are discussing Metered/Monitored PDUs….

METERED/MONITORED PDU
The NEXION Metered/Monitored PDU has all the features of the Basic PDU but also provides for real-time monitoring of the electrical characteristics (Voltage and Current) of the total load connected to the PDU. An LCD screen displays all the information in real-time.
Apart from Voltage and Current Meters, a Temperature meter/monitoring device is also available, allowing real-time monitoring of the ambient temperature. The temperature is displayed on an LCD screen. Temperature warning alarms can be set – Early Temperature warning, Late Temperature warning, and Alarm Temperature – all temperature values (in ᵒC or ᵒF) at the discretion of the Data/Server Room Manager.
All the metering/monitoring functions for Voltage, Current, and Temperature for all the load or for individual sockets can also be remotely controlled using the NEXION Intelligent PDU.

PDUs –KNOW MORE! (PART TWO)
SWITCHED PDU
In Part One we discussed Basic PDUs. Today we are discussing Switched PDUs.
Like the NEXION Basic PDU, the NEXION Switched PDU distributes power to multiple sockets, provides protection against surges and, has a mains switch. However, unlike the Basic PDU, each outlet on the Switched PDU has an individual switch. This allows the individual control of each outlet and therefore the device connected to the outlet. There can also be local and/or remote switching (using an Intelligent PDU) of the individual sockets. This will be discussed later under Intelligent PDUs.

PDUs –KNOW MORE! (PART ONE)
In an earlier post, we discussed extensively about PDUs. You can visit (https://www.numeriquelimited.com/2021/10/27/power-distribution-unit-pdu/) to know more about the functions and uses of a PDU. We will only discuss the meanings, functions, and differences between these types of PDU Terminologies
BASIC PDU
The Basic PDU is the simplest type of PDU. It takes power from a source and distributes it to multiple sockets (number of ways). The NEXION Basic PDU provides protection against surges and, comes standard with the main switch to switch all the sockets on/off. The common Basic PDU is just bare without any protection device or a mains switch, unlike the NEXION Basic PDU.
It can come in any number of Ways and any assortment of Sockets at your discretion.
The Basic PDUs can come as 1-phase or 3-phase PDUs.

SOLDERING: THE TRILOGY OF SOLDERING
In soldering there are three key elements that are important and inseparable:
A. Heat;
B. Solder; and,
C. Soldering Flux
If any of the three is missing, good quality soldering cannot be achieved. The soldered joint and the entire process becomes an exercise in futility.
We, at NUMERIQUE LIMITED, describe these three component parts as the “Trilogy of Soldering”.
What is Soldering?
Soldering is a process in which two or more metal items are joined together by melting a filler metal. The melted filler metal is then allowed into the joint. The filler metal (usually called solder) has a relatively lower melting point than the metals being joined together.
The soldering process accomplishes a strong bond between the metal items by joining them together. In this procedure, the solder, an alloy of tin and lead flows over the two pre-heated metal items and binds them together. Only the solder melts, not the metal items that are being soldered.
To successfully achieve this process all the three key elements of the trilogy must be present.
A. HEAT
Heat (the first element of the “Trilogy of Soldering”) is applied to the items to be joined and the solder. The heat melts the solder and raises the temperature of the items to be joined. It is inseparable from the process. The heat comes from a soldering iron or soldering station. Soldering irons come in different forms, sizes, and power ratings. Usually, they are powered from the mains but can come as battery-powered or butane gas-powered.
There are different methods for applying heat. Heat can be applied using Hand Soldering, Dip Soldering, Wave Soldering, Reflow Soldering, etc.
B. SOLDER
Solder is the alloy material used to bond two metals together in the soldering process. A soft alloy that melts when heated and allows the formation of an intermetallic bond between itself and the metals to be bonded together. It has a lower melting point and is an alloy of Tin (60%) and Lead (40%). For electronic soldering, the preferred solder alloy is Tin (63%) and Lead (37%). Solder is the second part of the “Trilogy of Soldering”. It is inseparable from the soldering process.
Solder for electronic hand soldering comes as solder wire. They come in rolls of different wire lengths, wire diameters, and Tin/Lead alloy compositions. Solder also comes as Solder Paste (for SMT Hand and Reflow Soldering), Solder Bars (for Dip and Wave Soldering).
C. SOLDERING FLUX
To understand the role of soldering flux in the soldering process, let us look at the soldering process in detail.
When hot solder comes in contact with a metallic surface, a metal-solvent action takes place. The solder dissolves and penetrates the metal surface. The molecules of the solder and the metal blend to form a new alloy, one that's part metal and part solder. This solvent action is called WETTING and forms the intermetallic bond between the parts. Wetting can ONLY OCCUR if the surface of the metal is free of contamination and from the oxide film that forms when the metal is exposed to air.
When metals are exposed to the air they oxidize, i.e. they react with oxygen to form an oxide of that metal (e.g. rust is formed when the iron is exposed to air). Copper, tin, lead, etc. also similarly form oxides. When heat is applied in the soldering process, the rate of oxide formation increases with the temperature increase. Oxides do not allow the wetting action of solder to take place properly to form the intermetallic bond necessary for a good solder joint.
Soldering Flux, the third part of our “Trilogy of Soldering” is the material that removes the oxides from the metal surfaces. Without the soldering flux, the soldering process becomes a nightmare as oxides form uncontrollably and continuously.
Rosin flux is used for the soldering of electronic equipment. It comes in paste form to be applied directly onto the surfaces to be soldered. It also comes as an integral part (the core) of solder wires. Good quality solder wires always come with a rosin flux core.

On your Power Distribution Unit, knowing the right socket for your equipment plug can be a challenge.
The situation where equipment is imported with an electrical plug different from the usual 13A UK plug is very common. More disturbing is when you do not know the rating – now some research will be necessary. Or, the colour code of the plug is unknown – dangerous to cut off and rewire with a 13A plug. What do you do?
No need to take chances or be ignorant, NEXION Power Distribution Units (PDU) can be customized with any socket of your choice for your electrical plug. Know the type, name, and rating of your plug/socket by checking the chart at https://www.numeriquelimited.com/2021/10/29/know-your-pdu-sockets/
We can provide:
British;
American (different types and specs);
French/German (European);
Australian;
Chinese;
The Universal socket;
IEC (different types and specs);
Industrial (different specs)
We really do love our NEXION PDU customers; No mistakes with your PDU Sockets; Lifetime Support is guaranteed for all NEXION PDUs.

What is a Power Distribution Unit (PDU)?
The Power Distribution Unit (PDU) provides multiple electrical sockets. The PDU sockets can be the same type of socket or different country/specification sockets. They are more relevant in Data Centres or Server Rooms when connecting different types of equipment from multiple sources.
Have you ever had the problem of having many pieces of equipment that you have to plug into electrical sockets at the same time? And usually in the same place? Not to mention buying quality equipment with different types of plugs and you cannot find the right socket to plug them. In Data Centres or Server Rooms, additional challenges are faced in power protection, monitoring, control and management situations.

This kind of scenario can be mind-numbing and daunting especially if you cannot think of a solution. Normally, you find one or two sockets around, yet you have so many items to plug. Do you opt for additional wiring or sockets? Very unsightly, time-consuming and expensive. Or do you buy extension sockets? Most of the time, they are very unreliable and of low quality.

The solution is the Power Distribution Unit (or PDU). The PDU is a device fitted with multiple sockets designed to distribute electric power quickly and efficiently wherever the need arises.
The PDU finds a perfect niche in Data Centres and Server Rooms because of its flexibility in providing multiple sockets. The number of sockets depends on your need. This determines the “number of ways” of the PDU that you need.
PDUs can come with different types of sockets. When using our NEXION PDU, you can mix and match different countries/specifications. Power protection, monitoring, control and management solutions can also be provided. For all these, NEXION PDU is the ultimate solution.
In today’s business environment, efficient power supply to the different equipment is key to the success or otherwise of the business. For the effective running of the office, equipment room, Data Centre, Server Room or anywhere you find a cluster of equipment, it is not negotiable. The growth and performance are directly impacted by the quality and efficiency of its power distributing system.
Whether in homes, offices, Data Centres, or Server Rooms, Power Distribution Units, PDUs are relied on to improve power management efficiency, uptime, and growth.
The NEXION PDU comes with a novel design that combines reliable quality with reasonable prices and high-quality after-sales services.
Have problems with space in your network equipment rack or cabinet? Have problems fixing that equipment in your rack? NEXION PDUs come in different sizes to suit your rack requirement. They can come as 2U, 1.5U or 1U rack heights to give maximum freedom. NEXION PDUs come as either Vertical Mounting or Horizontal Mounting to give the user more flexibility.

Did you order that equipment from abroad and you received it with a power plug that is different? To make things worse, there is no recognizable socket that you can use. The solution is with NEXION Power Distribution Units (PDU). We provide different types of country sockets depending on the customer’s needs. Our PDUs can come with British, American, French, German, Australian, Chinese or the Universal socket styles.

NEXION PDUs offer all these advantages and many more. We offer lifetime support for our NEXION Power Distribution Units (PDUs) – if it fails we fix it throughout the lifetime of the PDU.
