Farallon Communications PB 1400 - Manual (Page 17)

Operation 17
After you’ve finished reviewing Ethernet statistics, click the Cancel
button to close the dialog box. Then select the Off radio button in the
PB 1400 EN Diagnostics control panel to disable statistics collection.
This allows your networking software to work more efficiently.
To run diagnostic tests on your PB 1400 Ethernet Card and its
communication with the network, click the Diagnostics… button in
the PB 1400 EN Diagnostics control panel.
Important: Before running the tests, be sure that the PB 1400
Ethernet Card is not connected to a heavily used network. The tests
involve signalling which could disrupt other network operations. In
addition, some tests will fail unless the network link is established.
(The green link LED for the port on the PB 1400 Ethernet Card must
be lit.)
