Test-Um NT955 Series
Hub Flash Test

This test sends a link signal to test for active Ethernet equipment. This is

the only test that runs with other Ethernet equipment.

1. From the Data Manual Test screen, select Hub Flash

2. From the drop down menu, select a specific data rate or Any if

you wish to have the hub and Validator-NT auto negotiate the

speed. (Figure 5.8)

3. In 10Mb or 100Mb mode, the Validator-NT can be set to emulate

a NIC, a HUB or to Auto (auto MDI/MDIX) mode using the drop

down menu. If plugging into a hub, the Validator-NT must be set

to NIC or Auto modes. The Auto mode can be used most of the

time, but it may be necessary to select Hub or NIC mode when

connecting to a network device that can “sleep” such as a laptop

computer to wake it up.
