Hi All,
We've had a failure of an SFP+ board for no apparent reason. We've not
put any work into trouble shooting except to isolate the failure to the
SFP+ board, as opposed to a ROACH2 or optical transceiver.
Has anyone else experienced failures?
The two PHY chips on these boards run very
Hi Rich,
On a related topic, we lost one SFP+ port on a board after it had been running
for O(1) month. We replaced it w/ another board. The same port was dead on the
new mezz. board pointing to the problem being w/ the ROACH2 board.
Best,
Lincoln

Hi Rich,
So far we haven't had any trouble with the SFP+ boards (8 total) in
our vegas machine. I guess they've been powered up continuously and
in use for around a year now.
We were concerned about how warm the PHY chips run so I spent a
little time looking into it. The datasheet says:
hi jason,
thanks for the temperature data and measurements.
were your temperature measurements in the
standard roach2 enclosure?
i think the VEGAS SFP+ PHY's are mounted
differently and have different cooling than the
standard roach2 enclosure.
best wishes,
dan

Hi Dan,
One measurement was made with a bare roach2 board just sitting on the
bench in the lab.
The other was made with the vertical mount roach2 arrangement that we
use in the vegas rack.
Thanks,
Jason
