Network Cabling Tidy Up

spaghetti network

If you are supporting this network, how you think about this?

Simple question : Where do i start for making this look better?

Advance question(answer if in the mood) : tools and practices to map it from the beggining and document the mappings.

Reason #1: To Maintain Efficiency

The more disorganized the telecom cables are, the harder it is to make changes, troubleshoot problems, and upgrade equipment. If patch cables are a tangled mess and hanging in front of equipment, then accessing the equipment is much more difficult when something needs to be added or repaired. It also makes things more difficult in case a workstation cable needs to be troubleshot or new cables need to be added to the telecom room. All of this just wastes time and resources that could be better spent on tasks that are more critical to the organization.

Reason #2: To Improve Network Performance and Stability

The messier the data cables are, the more likely it is that equipment connections can become loose, disconnected or damaged when performing routine maintenance. It is also likely that some of the cables and connections are of poor quality, which can contribute to network outages or decreased performance.

A dangling mess of cables in front of equipment can also impede the circulation of air and cause switches, servers, or other active equipment to work harder and potentially overheat.

Furthermore, when performing moves, adds, and changes (MAC) work, having messy and disorganized data cables increases the risk of someone mistakenly disconnecting or even causing permanent damage to a vital piece of equipment.

Let’s face it, most people don’t really care until they start to feel the impacts themselves—in the form of slower e`mail, garbled phone conversations, intermittent or unplanned network outages, or slow Internet. Each of these things are a nuisance at best—but for most organizations, it could severely impact employee productivity and affect the bottom line. For other organizations, such as financial institutions and hospitals, these outages could pose a more serious threat and have a significant impact on the people those organizations serve.

Reason #3: To Reduce the Risk of Electrical Fire

In a messy, disorganized telecom room, electrical connections to active equipment will likely be a similar mess. It’s a rare case when the network patch cables are a complete mess but the power cords are properly organized and connected. The “daisy-chaining” of extension cords and power strips can easily overload an electrical outlet, which in extreme cases could cause electrical sparking or overheating that may ignite a fire.

Performing a telecom room cleanup will help reveal improperly-connected power cords and allow for the proper distribution of power to critical equipment—reducing the risk of fires and accidental power outages.

Reason #4: To Maintain a Professional Appearance

Appearances matter to employees, customers, and visitors—a clean, tidy, and organized space provides a positive impression at every level. For this reason, much attention is given to the design and layout of the overall office space, furnishings and especially the reception area.

A clean work area is one that employees can be proud of and be more inclined to take extra care to keep neat and organized. It also projects a professional image for visiting clients or other guests.

Although most clients, visitors and even employees may not see or be exposed to the telecom room, the same principles apply. A messy and disorganized telecom room can be misunderstood as being a reflection of the entire organization and could impact the organization’s ability to recruit or retain qualified IT personnel.

A side benefit of cleaning up telecom room cabling is that it makes things much easier to clean and maintain—which helps improve the appearance, performance and reduce fire hazards.

Cat5 vs Cat5e vs Cat6 – Which Should You Use?

Cat5 vs Cat5e

  • Network support – CAT 5 cable will support 10BASE-T and 100BASE-T network standards, that is it supports networks running at 10 Mbps or 100 Mbps.  CAT 5e is an enhanced version of Cat5 that adds specifications for crosstalk (see below). Cat5e cable is completely backwards compatible with Cat5, and can be used in any application in which you would normally use Cat5 cable. However, the added specifications of Cat5e enable it to support Gigabit Ethernet (1000BASE-T), or networks running at 1000 Mbps.
  • Crosstalk – Crosstalk is the “bleeding” of signals between one cable into another, due to a process called induction. This effect can result in slow network transfer speeds, and can even completely block the transfer of signals over the cable. Cat5e cable has been improved over Cat5 cable in this respect, and crosstalk has been greatly reduced.
  • Bandwidth – The bandwidth of a given conveyance media is essentially it’s information carrying capacity. The greater the bandwidth of a system, the faster it is able to push data across a network. Cat5 is rated at 100Mhz while Cat5e is rated at 350Mhz. This coupled with other more stringent specifications makes Cat5e ideally suited for networks which plan to operate at Gigabit Ethernet speeds.
  • Bottom Line: If you plan on to implement Gigabit Ethernet, go with Cat5e. Also, the small increase in price of Cat5e over Cat5 is more than made up for by “future proofing” your network’s cabling infrastructure.


Cat5e vs Cat6

There is a great deal of debate among people about whether new cabling installations should use Cat5e or Cat6. Many people incorrectly assume that by running Cat6 they will then have a Gigabit Ethernet. However, in order to achieve true Gigabit Ethernet speeds, every single component on a network must be gigabit rated, such as the switches, hubs and network interface cards. This isn’t to say that there aren’t differences between Cat5e and Cat6, however. The general difference between category 5e and category 6 is in the transmission performance. While Cat5e can support gigabit speeds, Cat6 is certified to handle gigabit Ethernet. Additionally, the Cat6 specification is better suited toward environments that are generally unfriendly to twisted pair cabling. This includes areas that have lots of interference from things like power lines, lights, and manufacturing equipment. Still, for most applications, Cat5e is perfectly suitable and preferable to Cat6: it is more economical and performs almost as well. However, if you can be certain that all the components on your network are gigabit rated, and the volume of the data being transmitted calls for certified gigabit performance, then Cat6 is the way to go.

Structured Cabling – Proper Way

Structured Cabling vs Conventional Point-to-Point Cabling

What is structured cabling?

Structured Cabling… is defined as building or campus telecommunications cabling infrastructure that consists of a number of standardized smaller elements (structured).

A properly designed and installed structured cabling system provides a cabling infrastructure that delivers predictable performance as well as has the flexibility to accommodate moves, adds and changes; maximizes system availability, provides redundancy; and future proofs the usability of the cabling system.

What is the benefit of structured cabling system

What Are the Benefits of Structured Cabling?

Once again, organization is the key word here. With an organized structured cabling system the benefits are:

MAC’s are much quicker due to the fact that they are done in the MDA versus running long patch cords from equipment racks.
Potential for downtime is reduced as potential for human error is drastically reduced due to this organization.
Time savings: cable and port tracing becomes a much easier job with a structured cabling system.
Aesthetics: Never underestimate the looks! A structured cabling system will look much cleaner than a point to point method. Since the changes are done in the MDA versus at the hardware, the hardware can be cabled up and not touched in most instances. This allows the cabling in front of the switch to remain aesthetically pleasing.

What are Risk staying with conventional structured cabling system

Downtime!

With an unorganized messy cabling infrastructure, mistakes are commonly made. Incorrect ports are unplugged. Even worse is the messy cabling that gets in the way. Trying to remove a single cable from a large tangled mess can cause stress on the other cables. This stress can lead to network and channel errors in the hardware that are very difficult to trace.

Airflow: If a point to point method is used, the front and potentially the sides of the switch are congested with cabling bulk. This impedes the airflow that the switch needs to operate. This also translates to underfloor cooling; cabling congestion in this space hinders the airflow of the CRAC unit and can cause cooling issues.
