How to Design an Effective Data Center Cable Labeling System

How to Design an Effective Data Center Cable Labeling System - AnD Cable Management Blog

One of the things we talk about often in cable management besides having the right cable management and rack management systems that make your data center the most efficient, is using an effective cable labeling system.

The reason is simple. Nearly every technician has said, at one point or another, “I wish I had labeled that.” So whether you are just getting started with labels or you are labeling existing systems, the question is the same. How do you design an effective cable labeling system? Here are some things to consider.

Reduce, Reuse, Recycle

First, use a reusable label system. Not only is this better for the environment, it is better for your system as well. For example, if you use UniTag reusable cable labels, they snap on (and off) so you can mark and identify cables quickly.

But more importantly, if you change something or replace a cable, you simply remove the cable label and put it back on the new cable or in the new location. Easy, and with no waste. It saves time, too. There’s no need to reprint a label or find a different connector. 

Use the Right Cable Label Printer

This might seem like a no-brainer but starting with the right equipment when you’re developing an effective cable labeling system is just as important as when you are planning the layout or rearranging your data center. Ideally a label printer should be portable, have a large memory to load a variety of label styles, and should also be efficient.

Efficiency means long battery life, but also the efficient use of label cartridges. How often have you trimmed a label before applying it? Wouldn’t it be better of the label was the right size in the first place?

Epson LW-PX printers have innovative technology that reduces lead margins and will “rollback” before printing to prevent that waste. They also have auto full and half cut features that allow you to print a variety of labels in the field, and the large storage capacity means you’ll always have the labels you need at your disposal, from custom created ones to dozens of industry standard symbols.

The other important feature is toughness. Everyone has that employee who frequently has a case of the “dropsies.” But accidents happen to everyone, and printers get dropped, fall off of racks, or suffer even worse treatment. The Epson printer body meets MilSpec drop tests, and has a built in handle that makes it easier to carry (and less likely to be dropped).

Starting with the right printer and the right reusable label tags is the foundation for your cable labeling strategy.

Color Coded Cable Labels

One of the downfalls of a labeling strategy can be too many labels of the same color, and several flag ties that make it challenging to see what is going on. Using a variety of colors in a color coded cable run helps you identify cables at a glance, and can help you follow cables more easily.

Because you can use the Epson labels on any size of cable or group of cables, you ‘ll reduce label clutter, which comes with a whole host of advantages.

Label Size and Information Matters

Sometimes you need more detail than you can put in one line of type. Use labels that are large enough to include multiple lines of type, so your labels make sense to everyone in the data center. Remember, you might not be the one coming back to work on that particular server, so the more detail you include in your labels, the better.

This also impacts readability. A color can tell the technician what type of cable they are dealing with. The label itself tells them the greater detail they need to know to follow the cable and troubleshoot quickly. The reason for labels is that moment later on when a technician is troubleshooting.

Consider the question, “What would another technician need to know about this cable to work efficiently?” That’s the information that should be included in your label.

Best practice guide to a three line cable label:

  1. Near end termination – Port number on patch panel or hub or wall outlet number or physical location
  2. Far end termination – Patch panel location or hub/switch location and port number
  3. Cable purpose – circuit ID or functional description of a cable or patch cord
Three lines of text on the cable label tape and plastic cable label provides lots of space to record vital information

Label Wherever You Can

For label tags, removable adhesive label tape may be the best choice, but there are other applications your printer and your labels need to serve. You may need to label a heat shrink tube, or you may want a fluorescent label for some applications.

Epson Labelworks PX printers offer different kinds of label cartridges to meet different needs. You should encourage technicians, and remember yourself, those moments when you wish you had labeled something, even if it isn’t a cable. Instead of thinking, “I wish I had labeled that,” you can say, “I’m glad I labeled that.”

Have a Standard Cable Labeling Nomenclature

No matter what cable labeling system you have and what printer you use to implement it, it will all be for nothing unless everyone is on the same page. Think of it: one technician might call a group of cables one thing, and another tech might label it differently, or not understand the label on the cable.

Not only is it important to label, but part of your labeling system should include a “key” of terms, abbreviations, and names. Everyone should use the same “key” or system. That way, there is no misunderstanding about what a cable run is, or what that abbreviation really stands for.

Final Thoughts

Are there any secrets to an effective cable labeling system? Not really. It’s pretty simple:

  • Use the right tags and equipment
  • Use color coding where appropriate
  • Be consistent with terms and labels
  • Label everything that you might wish later was labeled
  • Include all relevant details on your labels

With the right cable labeling system, you’ll save time, money, and energy. Your installers and technicians will be more efficient, and overall your data center will be more profitable.

The Spaghetti Mess – Rack Cable Management Essentials

The Spaghetti Mess – Rack Cable Management Essentials - AnD Cable Management Blog

We often talk about the importance of network cable management in data centers, and how important it is to efficiency, airflow, equipment longevity, and more. But what about on managing cables on the rack itself? 

Jump to Section:

Do your racks have a ‘Spaghetti Mess’ of cables?

In fact, we know (because you’ve told us) that nearly everyone has encountered the “spaghetti mess” at some point or another. This is a bad thing, not just because of how it looks, but because of the possible damage, lack of efficiency, and even increased maintenance costs.

But there are solutions, and if you understand the essentials of rack cable management, things can be pretty simple for you. You don’t ever have to look at the “spaghetti mess” in your data center again. 

Let’s start at the beginning: 

The Server Rack Itself

First of all, we all know there are different kinds of racks and different sizes. While improving technology means some things are getting smaller, server components are actually getting larger. That means that wider racks, on the order of 23” cable racks or wider are more common. You can’t use a 19” cable rack for a 23” component. The end result will not only be ugly but could be disastrous.

In addition, racks, specifically in California but in other locations as well, must be built to withstand earthquakes and other natural disasters. It’s a pretty major requirement, and even if you aren’t in California, there may be state or local ordinances that cover the kind of racks you can use in your data center. The rack is the foundation for a good rack cable management system.

Racks also come in different levels of quality. Always remember that cheap is probably cheap for a reason. You want racks to not only be the right size, but to be sturdy and reliable. Cheap racks that bend, fit together poorly, and that don’t work well with standard adapters and rack cable managers will end up costing you more in the long run. Make sure you have the right rack for the right job. 

Rack Cable Managers

Rack cable managers, sometimes called horizontal lacing bars, are a critical part of cable management. There are a number of varieties, both horizontal and vertical. They are often classified by the amount of space they take up on the rack. 

Horizontal Zero U Cable Management Server Rack – 23″

For example, our ZeroU rack cable management systems doesn’t take up any rack space, allowing you to be more efficient with the use of your space, reducing the overall footprint of your servers. This means using fewer racks and leaving more space for airflow. 

A good rack cable management system also gives installers and maintenance personnel space to work. They have room to get tools and their hands in where needed, meaning they can work faster and more efficiently. 

Bundling and Labeling

Bundling like cables together keeps your racks looking neat, avoiding the spaghetti mess look. But it does more than that. Running like cables together reduces electromagnetic interference, makes finding what you are looking for easier, and again reduces maintenance time. 

Bundling can be done with zip ties, and while sometimes that is appropriate, most often Velcro is a better solution. It’s reusable, can be loosened or tightened as needed when doing adds, moves, and changes. 

The other important essential? Labeling. When was the last time you thought, “I wish I (or someone else) had labeled that?” When troubleshooting and executing repairs, a simple label can reduce the time needed to sort through cables exponentially. Also, if you properly and accurately label cables, you are less likely to forget where they should be terminated. They are less likely to get tangled as you install them, allowing you to avoid the spaghetti mess.

Cable Length and Rack Cable Management

Another simple way to avoid the Spaghetti mess? Be sure your cables are cut to the right length and terminate them appropriately. Network cables that are too long are much more likely to tangle or get wrapped around one another. 

The key is simply following the old carpenter’s rule: measure twice, cut once. You don’t want cables to be too short either. This can result in sharp bends and even breakage, and those things can result in data slowdowns or worse, failures. 

Have a Rack Cable Management Plan

What is the most important element of efficient rack cable management and avoiding the spaghetti mess? Having a plan and having everything on hand that you need. Whether you are renovating and updating your data center, building a new one, or replacing old components, develop a plan.

  • How Many? – Determine the size and number of racks you will need and order them ahead of time. 
  • Plan Ahead – Develop a plan to manage cables and order the horizontal rack organizers you will need – and vertical racks!
  • Network Cable Requirements – Determine the amount of cable and the type you will need. Order them ahead of time, but also make sure you have the terminals you will need on hand. 
  • Velcro! Need we say it again? – Make sure you have more than enough Velcro cable ties on hand to bundle cables as needed. 
  • Colored Zip Ties – While not always the best solution (see Velcro) overall, zip ties still have their place in rack cable management. Have plenty on hand to aid with cable routing. 
  • Cable Labels – have plenty of custom labels on hand and use them. Make sure every installer is on the same page as far as the way things will be labelled. 

A plan will keep the spaghetti mess from developing in the first place, saving you hours later on.
