<br>
I inherited a [small-medium sized] lab with several (a dozen or so) old SunFire
440s and a couple Sun Netra 440s. Additional air-conditioning was added at a
later date (no precautions, never mind "proper", had been taken
against dust & etc). Of the 440s, several power-supplies were packed tight
with dust and their fans failed (if not the entire power supply), several
system fans also failed in time seemingly simply due to the age. <br>
<br>
The Sun Fire 440 servers ran for several weeks at a time before repairs
(various reasons) and survived... But the Netra 440s were added at a later date
and haven't gone through the same torture - so no practical information there
to share.<br>
<br>
In any case, it's an interesting finding; do you have a source (might help me
with managers in the future to get repairs done faster :) )?<br>

<br>
I saw a notice today that indicates that the thing will eventually overheat if
only one fan dies. The notice did not mention any specifics about the
ambient temp or airflow conditions.<br>
<br>
If this were a common occurrence, you'd think that it would have gotten more
press by now.<br>
<br>
Thanks,<br>
