Busy network engineers may feel as if they lack the time for proper network rack cable management. However, a disorganized mess of patch cords and cables will only make maintenance more difficult and time-consuming in the long run. Improper cable management also increases the risk of network downtime and heat retention in the server rack or cabinet.
In a previous post, we discussed the benefits of cable management and described how vertical and horizontal cable managers help keep cords organized. There are also steps network administrators can take to keep cabling neat and prevent headaches down the road.
While structured cabling follows well-defined standards, there is more flexibility when installing patch cords and other cables within server racks and cabinets. However, experienced network engineers and cable installers have found that following these tips can help ensure high-quality, well-managed results.
In carpentry, one of the most important rules is to “measure twice, cut once.” The same holds true for network cables. Excess cabling increases costs and leads to more tangling. By measuring carefully, network engineers can reduce cable waste and create a neater rack environment. Ideally, organizations should purchase custom network cables of the exact length needed.
Some manufacturers try to keep costs low by scrimping on sheathing and using narrow copper cores. However, this increases the risk of signal loss and makes cables more likely to snap or stretch. High-quality cables cost more but pay off in the long run by reducing the risk of failure and network problems.
Although cables appear to be flexible and robust, they require proper handling to prevent damage. Sharp bends and twists can result in poor data transmission and intermittent network problems. Network cables should have just enough slack for proper routing without excess.
Bundling power cables with network cables can create electromagnetic interference, so it’s best to separate them. Cable managers make it easy to organize various cable types to minimize interference.
Experienced network engineers recognize the importance of proper termination. Although it takes extra time, it will reduce troubleshooting headaches. If a connection is lost whenever a network cable moves, the termination should be redone.
The value of labels cannot be overstated. Proper labeling of cables in the network rack or cabinet allows administrators to easily identify cables they may want to replace and limits the potential for mistakes. Ideally, patch cables should be labeled on both ends, using a consistent format, so that they can be traced later. Cable jackets of various colors can be used to facilitate further identification.
Growth and change are inevitable in today’s networking environment. Well-managed patch cords will facilitate moves, adds, and changes and minimize the risk of a technician unplugging the wrong cable. Effective network rack cable management is no longer a luxury, it’s a necessity.
