I am facing a problem in my LAN connection. We have CAT 6 straight cable around 80 feet coming directly from one department. The cable is patched in patch panel on T568-B wiring standard. Then we connect that patch panel cable to un-managed switch with another straight cable patch cord.
EDIT: Another great test would be to make (or take, if available) another straight cable (100ft; B wiring) and run it directly from the machine that is not connecting, and plug it directly into the switch (on the same port as before, at first) If you get connection then something is either wrong with your punch or the port on the patch panel.

I have patched it to different port on patch panel but same result. Neither any change in network nor in configurations. There is no open pair. After checking it from different angles many times, finally i have made RJ45 connectors on both ends for checking. But it is showing same result as all LEDs are up 1-2-3-4-5-6-7-8 in correct sequence but with Non-Parallel" error. See cable tester in attached picture.
As this computer is set for some data feeding purpose only. I have replaced that green pair with blue one at both ends. And since then it is working fine. I will contact some professional to check that wire completely. Thanks
There is nothing wrong with your tester.
There are 8 strands in an unshielded network cable which is what you tested in your video.
A shielded cable also has a grounded metal sheath surrounding the 8 strands. The G on your tester refers to this.
I have a similar tester but in mine the shield is referred to as "Shield".
In computer programming and software testing, smoke testing (also confidence testing, sanity testing,[1] build verification test (BVT)[2][3][4] and build acceptance test) is preliminary testing or sanity testing to reveal simple failures severe enough to, for example, reject a prospective software release. Smoke tests are a subset of test cases that cover the most important functionality of a component or system, used to aid assessment of whether main functions of the software appear to work correctly.[1][2] When used to determine if a computer program should be subjected to further, more fine-grained testing, a smoke test may be called a pretest[5] or an intake test.[1] Alternatively, it is a set of tests run on each new build of a product to verify that the build is testable before the build is released into the hands of the test team.[6] In the DevOps paradigm, use of a build verification test step is one hallmark of the continuous integration maturity stage.[7]
For example, a smoke test may address basic questions like "does the program run?", "does the user interface open?", or "does clicking the main button do anything?" The process of smoke testing aims to determine whether the application is so badly broken as to make further immediate testing unnecessary. As the book Lessons Learned in Software Testing[8] puts it, "smoke tests broadly cover product features in a limited time [...] if key features don't work or if key bugs haven't yet been fixed, your team won't waste further time installing or testing".[3]
Frequent reintegration with smoke testing is among industry best practices.[9][need quotation to verify] Ideally, every commit to a source code repository should trigger a Continuous Integration build, to identify regressions as soon as possible. If builds take too long, you might batch up several commits into one build, or very large systems might be rebuilt once a day. Overall, rebuild and retest as often as you can.
Smoke testing is also done by testers before accepting a build for further testing. Microsoft claims that after code reviews, "smoke testing is the most cost-effective method for identifying and fixing defects in software".[10]
Smoke tests can be functional tests or unit tests. Functional tests exercise the complete program with various inputs. Unit tests exercise individual functions, subroutines, or object methods. Functional tests may comprise a scripted series of program inputs, possibly even with an automated mechanism for controlling mouse movements. Unit tests can be implemented either as separate functions within the code itself, or else as a driver layer that links to the code without altering the code being tested.[citation needed]
In Lessons Learned in Software Testing, Cem Kaner, James Bach, and Brett Pettichord provided the origin of the term: "The phrase smoke test comes from electronic hardware testing. You plug in a new board and turn on the power. If you see smoke coming from the board, turn off the power. You don't have to do any more testing."[3]
The MDT modular formation dynamics tester makes real-time flowline resistivity measurements at the probe module to discriminate between formation fluids and filtrate from water- and oil-based muds. Until an acceptably low level of contamination can be recovered, formation fluid is excluded from sample recovery.
In additional to resistivity measurement, numerous modules can be integrated with the MDT tester for optical monitoring, from a single absorption spectrometer through comprehensive analysis at reservoir conditions by the InSitu Fluid Analyzer real-time downhole fluid analysis system.
In conjunction with DFA, the faster collection of more-representative samples gives you real-time understanding of hydrocarbon properties at reservoir PVT conditions while the MDT tester is still in the borehole. Your formation testing program can be easily modified as real-time data warrants to avoid extended subsequent production testing or lengthy additional PVT laboratory work.
The MRPA consists of two inflatable high-performance packer elements that effectively seal against the borehole wall to isolate up to an 11-ft interval. The asymmetrical packer design reduces sticking and bulging potential, and operational reliability is further enhanced by the autoretract mechanism (ARM). The ARM applies a longitudinal tensile force to assist in retracting the packers after deflation, in turn minimizing drag.
The dual-probe module (MRPS) of the MDT tester has two back-to-back probes, mounted 180 apart for determining horizontal and vertical permeability and conducting vertical interference testing to determine near-wellbore permeability anisotropy
The extensive modularity of the MDT modular formation dynamics tester makes it easily configurable to achieve your formation evaluation goals. Our reservoir evaluation experts meet with you to design the module arrangement and specify test procedures from the wide variety of productivity and permeability tests along with fluid extraction and sampling, usually achievable in a single run of the toolstring. We monitor in situ pressure and fluid measurements in real time to ensure that the job objectives are met. Our multidisciplinary interpretation experts then work with you as needed to leverage this powerful data, such as building predictive reservoir fluid models to determine compositional gradation and reservoir connectivity across the field.
The InSitu Fluid Analyzer system can be deployed as an MDT tester module for obtaining a comprehensive set of fluid measurements at reservoir conditions, spanning direct indicators of fluid sample purity to extensive DFA, for even more answers from a single run of the MDT formation tester.
PIM is a growing issue for cellular network operators. PIM issues may occur as existing equipment ages, when co-locating new carriers, or when installing new equipment. PIM is a particular issue when overlaying (diplexing) new carriers into old antenna runs.
The PIM test is a measure of system linearity while a Return Loss measurement is concerned with impedance changes. It is important to remember that they are two independent tests,consisting of mostly unrelated parameters that are testing opposite performance conditions within a cellular system.
It is possible to have a PIM test pass while Return Loss fails, or PIM fail while Return Loss passes. Essentially, PIM testing will not find high Insertion Loss and Return Loss will not find high PIM. Line sweeps and PIM testing are both important.
Some cable faults show up best with a PIM test. For example, if an antenna feed line has a connector with metal chips floating around inside, it is highly likely that it will fail a PIM test while the line sweep passes. The antenna run most certainly possesses nearly ideal impedance characteristics, but the presence of metal flakes bouncing around will cause the PIM test to fail. It is also an indication that the connector was not fitted correctly.
Another possible cause of PIM test failures is braided RF cables. These cables will test perfectly in a Return Loss or VSWR test, but generally possess only average PIM performance. The braided outer conductor can act like hundreds of loose connections that behave poorlywhen tested for PIM, particularly as they age. For permanent installations, braided cables are not recommended.
Some cable faults show up best in a Return Loss or VSWR test. A good example is a dented or pinched main feeder cable, which will have an impedance mismatch at the point of thedamage, but may still be linear. Return loss testing will quickly spot this sort of damage, although PIM testing cannot.
With the rollout of spread-spectrum modulation techniques, such as W-CDMA, and OFDM technologies like LTE and WiMAX, it has become essential to test both PIM and impedanceparameters both correctly and accurately.
PIM lowers the reliability, capacity and data rate of cellular systems. It does this by limiting the receive sensitivity. In the past, RF engineers could select channel frequencies that would notproduce PIM in the desired receive bands. However, as cellular usage grows, the licensed spectrum has become crowded. Engineers must often select less desirable RF carrierfrequencies and accept potential PIM issues. Compounding this problem, existing antenna systems and infrastructure are aging, making any PIM that does occur stronger. 152ee80cbc
