Chapter 2: Overview
2. Overview
2.1 Introduction
Over half of all network problems are caused by faulty cables.
And with network speeds increasing exponentially, the need for
affordable, sophisticated test equipment is more apparent than
ever before.
With the CAT5/5e/6 LAN Performance Verifier, you can check
your network cabling and devices to ensure they work at the
speeds promised by their manufacturers. Ideal for IT managers
and technicians responsible for cabling and network hardware,
the CAT5/5e/6 LAN Performance Verifier enables you to quickly
spot slow cables, bad connector s, incorrect wiring, improper
lengths, and low signal levels from hubs, switches, PCs, and
other LAN hardware. It digitally certifies cables and devices in
Gigabit Ethernet networks.
You can also decode your network devices’ capabilities and
signal levels, and even place the tester in-line between any two
devices to determine the negotiated speed. Or perform singleside tests without powering down devices or unplugging cables.
2.2 Features
• Verify that cables and LAN hardware perform at their
advertised speeds.
• High- speed TDR provides nanosecond -accurate results.
• Locates opens, shorts, and splits, and pinpoints the exact
distance to the fault or split.
• Stores up to 250 test results you can download to your PC via
the USB port.
• Includes a toner/probe to locate wires in crowded wiring
closets.
• Tests 10 -, 100-, and 100 0-Mbps devices for data signal levels.

CAT5/6 cable.
2.4 Applications
Works with UTP and all Ethernet devices: Unlike traditional
certifiers, the LAN Performance Verifier (LPV) uses digital circuitry and digital testing techniques to per form it s tasks. These tests
include traditional TIA568 cable verification (length, opens,
shorts, split pairs, wire map) for unshielded twisted pair (UTP)
plus the LPV's own sophisticated crosstalk, timing, and cable
parameter tests that yield a UTP cable's category (CAT3, CAT5,
CAT5e, CAT6) and speed capability (10, 100, 1000 Mbps). And
the LPV can use your own network devices (hubs, switches, PCs)
to test UTP cables with real data. The LAN Performance Verifier
analyzes links and data from all types of hubs, switches, and
PCs. It performs both single-sided tests for advertised speed (10,
100, 1000 Mbps, and duplex) and inline tests (between devices)
for negotiated speed. The engine of the LPV circuitry is capable
of 1 nanosecond resolution.
Works with coax cable: Use the LPV to test for the length of
the cable, opens, shorts, wiremap, and distance to any faults
that might exist. As with UTP, coax can be toned with the toner
feature and test results can be stored in the LPV’s flash memory
for printing later. No LPV tests are performed on coax cable.
724-746-5500 | blackbox.com Page 11
Chapter 2: Overview
What is LAN Performance Verification?
LAN performance verification means that a UTP cable passed a
prescribed battery of tests and is therefore not likely to cause
problems later. The LPV has two levels of verification:
LPV Level 1: Performed with the Main Unit and the Remote
Probe, Level 1 tests the cable for length; opens, shorts, split pairs
and distance to the fault; wire map (displays cable wiring); NEXT
and FEXT (crosstalk tests); propagation delay (time to transit
cable); skew (time delay between pairs); cable category (CAT3,
5, 5e, 6); and speed projection (10, 100, 1000 Mbps).
LPV Level 2: Includes all Level 1 tests plus it takes advantage of
a real live data source (hub, switch, or PC) to test for attenuation
and device type. An LPV Level 2 test verifies speed of both the
cable and the L AN device.
Networks are installed in steps. First, cables are installed. Then
hubs, switches, and PCs follow. Cables and network interfaces
are known as the physical layer. The higher software layers
provide addressing, file transfers. etc. If the physical layer does
not work, the communications layers (soft ware) will not work.
Debugging cables, ports, and network software together is
time-consuming, frustrating, and ultimately very expensive.
There are too many unknowns. Using a LAN Performance
Verifier on your cables eliminates unknowns, making it easier to
get a network up and running. And, once the hardware is
operational, you can run software layer tests (ping, etc.) from
any workstation (see Appendix B).
What is the best time to LAN Performance Vertify a cable?
The best time to vertify a cable is when the installer is still readily
available to repair any faults that are found. Installers should
verify before they leave, so that they will not lose money by
having to return to a job site to do warranty repairs. Network
professionals should also verify before the warranty period
expires.

Chapter 3: The 3 Phases of LAN Installation
3. The Three Phases of LAN Installation
The LP V is designed for the network installer, the network repair
person, and the IT manager. The tests used during the three
phases of LAN installation can also be used to troubleshoot
LANs that have operational problems.
The installation of a L AN is generally handled in phases. The
cabling is installed; then the switches and PCs are installed; and
then everything is connected. The LP V plays a role during all
three phases, saving countless hours of troubleshooting.
Phase I. Use the LPV during cable installation (before the
switches and PCs are installed). After the LAN cable has been
pulled through the building and terminated, it is good practice
to verify LAN performance. Verify that the cabling is terminated
properly and test that the cable is proper for the intended use
(for example, CAT5e for Gigabit networks).
Phase II. Use the LPV after the switches and PCs are installed.
Before connecting the cables to the switches and PCs, verify that
each switch port and PC are operational. This provides a wealth
of information:
It verifies that the device is ON (that is, it is transmitting); the
speed of the device (10, 100, 1000 Mbps) ; duplex; and other
features.
Phase III. Use the LPV when connecting the cabling to the
switches and PCs. With the cabling verified and LAN
Performance Verified (Phase I) and the switch and PCs checked
out (Phase II), all that remains is 1) getting the equipment communicating and 2) verifying each LAN link is performing at the
speed expected. To do this, use LAN Performance Verification
Level 2 to test the cable and port combinations. And use the
network tests inline capability to connect the LPV between 2
LAN devices to verif y the negotiated speed of the link.

Figure 6 -8. Stranded or Solid wire selection screen.
The LAN Performance Verifier has the unique ability to test both
cables constructed of stranded wire (commonly called “patch”
cables) and solid-core wire. Scroll to select the cable and press
Select.
How to tell the difference: If the cable is installed in a wall, it is
almost certainly a solid core wire. Preassembled cable with end
fittings already attached is usually stranded cable. Also, stranded
cable is more flexible than solid wire. If you bend the cable and it
does not attempt to spring back to its original shape, it is most
likely solid cable.
NOTE: The minimum length of each cable type is shown on the
screen for Verify Tests. If your cable is shorter than this,
use the Basic Cable Test. Once the selection is made,
cable testing will automatically commence.

Chapter 6: Operation
Figure 6 -9. Testing progress is shown on the screen.
Figure 6-10. Any problems will be displayed (see Appendix C).
During this phase of testing, information about length, opens,
shorts, split pairs, crosstalk, cable category, and speed is being
gathered and computed. If there are no cable problems, testing
continues until you are prompted to connect the Remote Probe
and perform a wire map test. If all is OK, testing will finish (the
“speed” screen is displayed).
NOTE: If there is a problem with the cable, the problem will be
displayed, and testing will be halted. The problem must
be corrected before testing can continue. See Appendix C
for examples of cable failures.
Complete results are immediately available for Review and
Saving after the test is completed. This “test now, review later”
feature greatly speeds up the test process when you have
multiple cable installations.
724-746-5500 | blackbox.com Page 25
Chapter 6: Operation
Time to test: Short cables take longer to test because fewer
measurements per pass are possible. The thousands of
measurements required are accomplished much faster on longer
cables than shorter cables.
Figure 6-11. Testing is halted
until the Remote Probe is connected.
The Remote Probe is required for the wire map to be
constructed. Plug the Remote Probe into the far end of the
cable. Tracer tones have been turned ON to help locate cables in
crowded areas (press the TRACE button on the Remote Probe
and hold it close to the cable to follow the tone). The Main
Unit’s wire map test is triggered when the Remote Probe is
connected to the far end of the cable (there are no buttons to
push). The wire map tests for correct cable pairing.
NOTE: The wire map is displaye d during the Review process, not
during the test.
Remote Probe LEDs. The Remote Probe needs to be connected
only for a brief period. Flashing LED(s) indicate the test is progressing. A steady LED indicates the test is completed. This saves
you an extra trip to retrieve the probe. If LED(s) continue to flash
the cable, the cable has a wiring problem. Disconnect the probe
and go to the Main Unit to see the results.
NOTE: If you plan to test to LAN Performance Verification Level
2, now is a good time to plug in the hub, switch, or P C (it
will save you a trip).
