7. RECOMMENDED TEST PROCEDURE
7.1 Testing Procedure
To test the units connect two M10s (or two M10IIs), one to each of two
previously isolated network segments, leaving all settings at the factory
default values.
1. Make an inter-segment file transfer and observe the LEDs on the M10II
units. The upload (MAU) and transmit (TX) lights on the sending unit
will turn on brightly. The receive (RX) and download (MAU) light on
the receiving unit will also turn on brightly. The transmit light (TX) on
the receiving radio and the receive light (RX) on the sending radio will
turn on dimly due to the acknowledgments. If other combinations of
LEDs occur, there may be something wrong. There should be expected,
bursts of traffic and dead time in any network file transfer and this
should not indicate a problem.
2. Next make a local file transfer between NICs on a single segment. You
will see the upload light (MAU) come on but not the transmit light (TX)
on the sending unit, and you should see no receive lights on the other
unit. You can simultaneously do a local file transfer on each segment
and if you attach LAN analyzers to each, you will see that each unit
simultaneously achieves wired speed.
3. Now attach a third segment with a third M10II. When you do an inter-
segment file transfer, the LEDs will be the same as before for the
intended receiver, but the third M10II will show only a receive light, not
a download light nor a dim transmit light. In this case, the M10II that
has the intended NIC attached will acknowledge and download the
packets. The other M10II will receive the packets but will not respond
with acknowledgments, and not download. You can also try three
simultaneous local file transfers, and you will see that each achieves
wired speed. You may also wish to try an inter-segment file transfer
between two of the segments and a simultaneous local file transfer on
the third segment.
