<p>In at least one case where this is observed, the TRX (RUS 01) is mounted in an RBS 6601 - (with rear fans running at full speed as there's nothing to connect to the EC)</p> Ericsson RBS 6xxx - Bug #5571: DUG can come up, but with Avail: "Power Off"https://projects.osmocom.org/issues/5571?journal_id=253092022-11-07T17:24:17Zlaforge

<ul></ul><p>Hello Keith,</p>
<p>Thats interesting. I also have issues with the DUG20 I am using for tests. It seems not to like frequent BSC restarts. I see the "TRX 0 not usable" message quite often. A power-cycle usually helps. Can you post your osmo-bsc.cfg as well?</p>
<p>Best regards.<br />Philipp</p> Ericsson RBS 6xxx - Bug #5571: DUG can come up, but with Avail: "Power Off"https://projects.osmocom.org/issues/5571?journal_id=253282022-11-08T17:10:47Zkeith
<ul></ul><p>Hi <a class="user active" href="https://projects.osmocom.org/users/15">dexter</a> I don't have the actual config that would have been used when I wrote this six month old ticket. The DUG that was in use died, and it's not the first one we have lost. I don't have a DUG deployed anywhere right now, not even in the lab, as the lab moved house and I have not got around to setting up an antenna rig yet.</p>
<p>That makes 2 we've lost after not so many hours of operation, (apart from the units where we destroyed the serial port with +36V on the GND rail- they still work otherwise) - I have a suspicion that dust might be the culprit. Not that this is related to this issue, I just wonder whether we can expect a DUG to survive if we are blasting cooling air through it that is not filtered or at least reasonably dust free, (IE, not in a wooden hut on top of a windy hill in a semi-desert)</p>
<p>Anyway, the config would have been fairly "standard", that is to say, not much deviation from the example configs that ship with osmo-bsc. One thing possibly relevant would be the sync. IIRC, I see this ticket's issue regardless of if there is a GPS unit present and sync is external, or if we take the clock from the icE1usb</p>
