Cat 6 Crimping

We recently made up a new batch of Cat 6 patch cables to connect newly installed cable runs. When we test the new patch cables with a four-pair tester, they test fine. However, when we plug them into our patch panels they fail from end to end. All of the new cables that were run to the patch panel were thoroughly tested from Patch Panel to Jack. After some experimenting we found out that we can make them pass by putting extreme upward pressure on them at the patch panel. We are thoroughly stumped!

Slow Networks

We have Cat 6 UTP cable run throughout our offices. Each floor has two Telecommunication Closets (East and West). On one floor, our east closet has all of its computers that are running slow on the network. We have ruled out just about everything. Can you offer any suggestions?

Plenum Cable

I am running Cat 6 cabling throughout my new home which is under construction. Much of the cabling will have to pass through the attic. I live in a very hot area and the attic temperatures can be quite high. Do I need to use Plenum rated cable for this?

Intermittently Slow Network Speeds

We have been experiencing intermittent slow speeds lately with newly installed network cable locations. We have a high quality RJ-45 crimper tool and use high quality components. We always test each new cable after it is installed and terminated. We suspect that there may be something intermittent happening with the connectors. What could be the problem?

Grounding Shielded Cabling Systems

I am a Professional Network Cabling Installer and we install a lot of Category 6 (and 6 A) A Shielded cabling systems for our customers. Our company is very specific in how we need to ground each sytem that we install. They say that we must install only one permanent source of Ground on the cable's shielding and that this ground be at the main patch panel and main frame. We are required to run a # 6 AWG copper conductor from the patch panel and rack frame to "building steel". I wonder why this is necessary since each cable picks up a ground source at two places, one being at the main switch and the other at the workstation where it is picked up by the computer's electrical plug (from the electrical outlet). So if the cable is already grounded in 2 places, why do we need to ground it a third time?
