Cable Definitions: What are Rolled Cables? |
In the Cisco world, a rolled cable is a cable used to manage a router or switch from the console port of that device. This cable is usually used when configuring one of these devices for the first time. A rolled cable connects the PC’s serial port (using a DB9 to RJ45 adaptor) to the router or switch’s console port. A rolled cable looks just like an Ethernet cable. The funny thing is that a rolled cable isn’t an Ethernet cable at all. In fact, it is a serial cable. You cannot use a rolled cable for an Ethernet cable, nor can you use an Ethernet cable for a rolled cable. What you can do is take a straight-through Ethernet cable, cut off one end, flip over the wires, and recrimp it to make your own rolled cable. |
Take Home |
In summary, what you need to take home from this article is: |
Category 5e cables are the most common type of Ethernet cabling today |
A straight-through cable is what you normally use to connect a PC to a hub or switch |
A crossover cable is a special type of Ethernet cable used to connect a PC to a PC or a switch to a switch |
A rolled cable isn’t an Ethernet cable at all but looks like one. It is used to connect a PC to a Cisco router or switch’s console port, for management. |
When you start learning about Cisco equipment and get further into networking, the different types of Ethernet cabling will come up. In fact, Ethernet cabling is an important topic on Cisco’s CCNA exam . So what do you need to know about Ethernet cabling? Let’s find out. |
Types of Ethernet cabling |
To start off with, you should know that not all Ethernet cabling is the same. If you go to a store you may find a variety of “categories” of cabling. These categories tell you the quality of the cabling. The quality determines, essentially, how much the cable can handle. Here are the categories that you need to know: |
Cat 3 – used for voice cabling and 10Mb Ethernet |
Cat 5 – used for 10/100Mb Ethernet and works for voice as well |
Cat 5E – Enhanced Cat 5 cabling that helps to prevent cross-talk, works for 10/100Mb and 1000Mb (or Gigabit Ethernet) |
Cat 6 – Like Cat 5E but with larger gauge wires, works for 10/100/1000Mb. This cable is better than Cat 5e for Gigabit Ethernet. |
Cat 7 – Also called Class F, this is fully-shielded cabling and supports up to 600Mhz. This is a relatively new type of cabling and isn’t used much. |
Most companies today are still using and even installing Category 5e as it works for the 100Mb Fast-Ethernet in use on almost every desktop PC. Plus, it is economical compared to the higher categories of cabling. If you go to a computer store and buy an Ethernet cable, 99% of the time it will be a Cat 5e cable. |
Normal Ethernet Cables |
Next up, you should be familiar with the different types of “ends” or “plugs” at each end of the cable. When you go to a computer store and buy that “regular” Ethernet cable, what you are really buying is a straight-through cable. This means that if you hold both ends side by side, the colors of each of the different smaller cables inside an Ethernet cable, will be in the same or |
