Be advised that along with the test and certification, you should also receive full documentation with the complete test results.
Very good baseline info should there be problems down the road.

However, your cabling vendor screwed up and they need to fix and recertify every single drop they've done for you like that. IMNSHO, any serious structured cabling contractor will use a CAT5/5e/6/7 etc cable certifier that does WAY more than a simple continuity test. While a $50 or $100 Siemens continuity checker is great for a quick and dirty inspection, nothing compares to certification. If your vendor isn't certifying your cable drops when they are installed, IMHO, you need to find a new vendor. They are possibly violating all kinds of cabling rules, not to mention possibly creating all kinds of NEC violations. Jonathan L.

Not checking A or B. It doesn't even test for cross-over. I needed to plugged one in to get the pattern. They definitely crossed the cables. They connected to the patch panel the same as all my other (B) connections, but the wall jack termination is A. So it makes sense that it tests as a cross. Doesn't seem like it should work, but I've been told it does. From: Jason Morris [mailto:jmor...@mjmc.com] Sent: Monday, May 24, 2010 5:07 PM To: NT System Admin Issues Subject: RE: basic wiring question Ummm. If the tester is just checking continuity and it's not checking 568a or b, then they most likely crossed the cables. If it's actually checking whether it's A or B, then you might need to change something on the tester since continuity is a 1 to 1 test. Without knowing the model of the tester I can't help you more than that. Jason From: Paul Everett [mailto:evere...@leementalhealth.org] Sent: Monday, May 24, 2010 4:02 PM To: NT System Admin Issues Subject: basic wiring question All of our network jacks are terminated using the 568B standard. I use a Paladin Tools cable checker to trouble-shoot any wire/connection issues. Everything is good when the light on the cable tester blinks on 1 thru 8 in order. If it misses a number I know something is amiss. Last week we hired a firm to run some new wires and they terminated the jacks using the 568A standard. Although we aren't experiencing any issues with these new connections (but it's possible none are being used yet), my cable tester blinks in this order: 36145278. Same as a cross-over cable. I know my patch cables can be terminated either way as long as both ends are done the same, but having the cabling in the rooms as cross-over? Is this really a problem? If not, it's going to suck having to remember that 36145278 is ok when checking connections with this tester.
