Thanks everyone. For the sake of time, we just swapped the xport from
another roach (roach was broken, but xport was not) and we're back in
business.
Given all the negative reports on this, it would probably be worthwhile
for us to implement an external hardware solution for auto powering on
our roaches for the long-term.
Thanks again,
Jason

I'm afraid we have also not had long-term success with the Lantronix X-port,
nor the Actel Fusion devices in ROACH-1. This is why they are not present in
ROACH-2. In my experience, I cannot advise anyone to rely on these devices in
production systems.

Hi all,
just to report that even some of our ROACH-1's Xport dead suddenly
loosing the great functions of remote power on/off ;(
We thought the same solution to use a low cost controller but not yet
implemented. We will do it when the new Roach2 rack will be ready.
Cheers,

Hi Jason,
I've encountered similar issues with R1's before. I think it comes back to
the xports simply being unreliable. I've heard of cases in which the xports
work for a few months but unpredictably stop working at some point. There have
also been cases in which the xport never works to begin with. The latter has
been the case with some of the LoFASM ROACH-1's; xport was dead out of the box.
In one particular case this became a problem for us since we really needed to
be able to access the auto power-on feature as well as be able to force the R1
on/off remotely. We ended up programming an arduino that was used as a 'digital
finger' that emulated the pressing of the power button on the chassis itself.
Our ROACH board at LoFASM-II at the LWA North Arm is configured this way.
Best of luck,
L

All,
We're having an issue with a roach1 in GB where we can't access the xport. It
doesn't seem to respond using a web browser to the default IP of 192.168.20.4.
We also had our sys admin add an entry for its MAC address to our DHCP server
and we still cannot communicate with it.
As far as I know, we have never even tried to access the xport on this roach,
much less accidentally set it to some IP we can't remember.
We know our laptop is configured correctly because we can access xport on one
of the other roaches here.
A few questions -- does anyone have a suggestion on how we could get into the
xport? Is there a way to reset it to the factory defaults by chance?
We need to do this to enable the "auto power-up" feature. Is there any other
way to enable this feature besides xport?
Thanks,
Jason
