The Fluke NetTool is an easy-to-use, effective way of testing network cables (Cable Testing), network connectivity between desktops and networks (Inline Mode), and PC configuration. The NetTool has two RJ-45 jacks on each side and six control buttons on the front of the unit. These buttons are used to navigate through the NetTools series of tests. The NetTool weighs about 200 grams and can run off four AA batteries or an optional AC adaptor.
The tool has a series of menus and sub menus that are easily navigable thanks to the four directional buttons and the central "select" button. Running an Auto test instantly detects your PC and network connection. It then shows the services available on the PC and network. Test results displayed include Problems and Protocols.
On the right hand side of the LCD display are two tricolour LED indicators. One indicates utilisation levels while the other LED indicates errors, collisions and whether or not a link pulse is present. Three icons on the LCD represent the NetTool, PC and Network. Selecting one of these icons allows testing of that device. It also displays cable status, duplex settings and link polarity. From here you can test Health, Servers and Addresses Used, as well as run a Segment ID check.
By plugging each end of a network cable into the RJ-45 jacks, the NetTool tells you the cable length, its pin-to-pin continuity and detects opens, shorts and split pairs. You can also run a wiremap test by plugging in the wiremap adaptor. Plug into a wall jack and run Autotest checks for Ethernet and Token Ring presence. Connecting the tool to a PC, and then to a the network connection jack allows discovery of services such as IP, NetBIOS and Netware servers, as well as IP and IPX routers and printers, and DLC printers.
We tested the NetTool on one of our workstations; it immediately detected a low pulse on the network cable connected to the switch. It also detected that the server was sending error packets back to the workstation, which would not have been detected as easily without the tool. It told us the services running on the machine (STMP and DNS), its configuration (MAC and IP addresses), and listed the protocols running (IPX).
Unfortunately, full testing functionality has to be purchased from Fluke. The NetTool allows for unlimited tests to one device, but must be upgraded after 50 tests between two devices. Fluke also provides software updates from their Web site.
