Dear OSF-Managers,
since a half year i have a unknown problem with the Minitransceiver for Thinwire
-Networks (DECXM-AA) from DEC:
the Transceivers went defective because the Power on this Transceiver doesn't
work. The LED's on the Transceiver are not working now.
The Transceivers are dead now.
Inside the Transceiver, the resistor near the Transformer is burnt. Maybe it is
for the little Powersupply? A new Resistor make the Transceiver work for a short
time (minutes) but the Transceiver does not work correct.
After replacing the defective one by another Transceiver (same type), everything
is okay.
This happens in different buildings, on different networks, on different
machines
- but only on Alpha (this transceiver we use only on Alpha's).
We using this transceivers, because with other one (for Example: Lantronix LTX-2
) the machines are hung sometimes (it seems, the other Transceivers are overloa-
ded).
My question:
DEC-service said that this is a unknown problem.
For me it seems, that this Transceivers (DECXM-AA) are not work longer than two
/three years. They are not very expensive, but i don't like machines, which will
unexpectely not work.
Does anyone have seen this?
