Using AutoTest, Switch, and Cable Test


Using AutoTest

AutoTest can test up to ten targets. These targets can be local or off-net targets (devices). You can enter the IP address or a DNS name. If you specify a target address without specifying a port number, AutoTest will perform an ICMP Ping to the target address. If you specify a port number, AutoTest will perform a TCP Connectivity test (SYN/ ACK). See figures 14 and 15.


Select Tools > AutoTest Configuration and enter the target address(s). Entering a port number is optional.

AutoTest will attempt to Ping/Connect to the target device three times. If Continuous is selected, the test will run until you exit the AutoTest screen.


Select AutoTest on the Home screen. AutoTest will run and the test results should look similar to figure 15.


The nearest switch is discovered and its name, port, VLAN ID, model, and IP address are displayed. Then the DHCP server information is displayed. Finally, the Gateway and DNS server(s) are displayed along with the target device(s).

Expand on each device to display the test results as shown below.




Using the Nearest Switch Test

The Switch test screen displays the nearest switch. The nearest switch is discovered by locating the “port advertisement” on the first few packets seen by LR-AT.



Select Flash Port to stimulate the switch to flash the LED on the port that the LR-AT is connected into. This can help locate the switch port in the closet. Set the Flash Port flash rate from slow to fast to differentiate from the other switch port LED flash rates.

Using the Cable Test

There are three use models for using the Cable screen:


  • Connect a cable from the top LR-AT RJ-45 connector into the side cable test RJ-45 connector to measure length and wire mapping.


  • Connect an open cable (non-terminated) into the top LR-AT RJ-45 connector and measure length. An unterminated cable can also be traced using a Fluke Networks IntelliTone tester and the Tone function.


  • Connect a cable into the top LR-AT RJ-45 connector and select Tone. Using a Fluke Networks IntelliTone tester, you can trace the wire or locate it in the switch closet.



Using PoE Feature

PoE is disabled by default. To enable PoE, select Tools > PoE Configuration, and check Enable PoE. Select the Class you want to verify. If you have purchased the LR-AT 2000, you can TruePowerTM test the Class. The results are displayed in the Autotest and Switch tests.


When you select a PoE Class higher than the switch can handle, LR-AT 2000 will provide the loaded results indicating the switch can not handle this Class setting. The LR-AT 1000 will display the unloaded results indicating voltage and wattage selected.


The following example was tested on a Class 3 (13w) switch. The tester PoE configuration was set to Class 4 (25w) with TruePowerTM disabled.


Figure 19 displays the AutoTest results and Figure 20 displays the Switch results. Notice in the Autotest results, the wire pair polarity, wattage requested and wattage received, voltage and PSE type are given.


PSE is the Power Sourcing Equipment rating, Type 1 (12.95W – 15.40W) and Type 2 (25.5W – 34.20W).



In the next example, the Switch results are shown with the same setup, i.e., no load, Class 4 (25.5w).



Using the Reflector Feature (LR-AT 2000 only)

The Reflector feature allows the LR-AT 2000 to be used as a remote device for Fluke Networks EtherScope Network Assistant, MetroScope Service Provider, and the OptiView Analyzer’s throughput performance tests.


See Reflector Configuration on page 14 for setting up this feature. Once set up, the device can be used as the remote responding device for throughput performance testing. There is no start or stop, and no results are displayed on the tester.


Using the Fiber Connection

Simply plug in the desired SFP adapter into the fiber port on the top of the tester and connect the fiber cable to the network. If both fiber and RJ-45 copper are connected to the network, the copper connection has priority.

Figure 23 shows the Switch results through a fiber connection with link, 1000 Mbps speed, full duplex, with a signal strength of 7.35dBm.





To prevent possible fire, electrical shock, personal injury, or damage to the tester:


  • Do not open the case. You cannot repair or replace parts in the case.
  • Use only replacement parts that are approved by Fluke Networks.
  • If you replace parts that are not specified as replacement parts, the warranty will not apply to the product and you can make the product dangerous to use.
  • Use only service centers that are approved by Fluke Networks.
