Re: [Mikrotik] 450G question

2011-03-24 Thread Martín Ruiz [Ibersystems.es] 
55ºC shown in the datasheet, but I have several 450Gs working with 24V and
60-65ºC. One of them, died 2 months ago and I'am changing from 24 to 12V.

I don't know what the temp was on my boards when they failed to
reboot after a firmware upgrade.  My 450Gs use 12V power supplies.
One supply on the 450G which failed to reboot on upgrade in the
field says it sees 11.4V from the power supply, according to MRTG.

In the 24 hours I've had MRTG setup to graph voltage and temp, the
voltage has been a constant 11.4v.  The temp has varied from 42 C
to 56 C.  Unfortunately the problem firmware upgrade happened a
week before I found time to add the temp and voltage monitoring to
the mrtg host templates.

How hot is too hot for these things?  I haven't found the answer
to that question via google searches after a couple of hours of
digging through the query results.

I have not seen that with any MT at all.

Plug in a serial console and see where it hangs.  Ultimately I would
just end up with a comfortable version of MT that works (to each their
own).  Be absolutely sure you update the firmware!!!  That is /sys
routerb pr and up

That is the part that blows up.  The OS upgrade goes smoothly.  Then
you see that there is a routerboard firmware upgrad and you have
to power cycle the board when it still hasn't come back 5 minutes
later.  I've seen that about 2 or 3 RB-450Gs when upgrading from
2.28 to 2.29.  I think I have 5 or 6 of the RB-450Gs.  When it
happens on the bench, I don't care.  One happenned in the field.
That wasn't good.

I have 3 RB-493Gs and, if I remember correctly, one of them had to
be power cycled.

Also, during Dennis' training class in Salt Lake, I had the same
issue with the RB-433 I was using.

On all of those, I was upgrading to 4.16 from various 4.11 or earlier
loads, whatever was preloaded on the board when they arrived here.

I've not seen it happen on my 5 RB-750Gs.

On all of these platforms, my sample sizes are too small to say x%
fail to reboot successfully after a firmware upgrade.

I just hooked up a serial cable to the router board 4450G and rebooted 
about 10 times and it says "rebooting . . ."
"Stopping services . . . " and just sits there. Its pretty random i had 
it happen back to back already.  i have never programmed anything on 
this board.

I had problems with 24V in 450s. Use 12V better, but the problems was with
heat 60-65ºC..
