GEM with Ethernet no longer responding?

[ejosterberg]

Hello,
I have a GEM with hardwired Ethernet, configured with an assigned (static lease) DHCP address, which no longer provides data via the btmon script. My script was connecting to the GEM on port 80.
The GEM is responding to ping and using nmap, the only listening port is 1461.

I'm remote and would like to know if there's any options to bring it back online remotely and what can be done to understand what happened to it and prevent future data-loss and interruption to monitoring?

Shutdown btmon.py and see if you can pull the GEM Setup Webpage (or try grabbing settings via btcfg.py http://lancet.mit.edu/mwall/projects/po ... n/btcfg.py).

does not respond to a browser or nmap. btmon was disabled for 4 hours, no change.

When was it purchased? Wondering if it has one of the old power supplies as per the notice at: https://www.brultech.com/contact.

Have you ever updated the F/W on the unit?

[ejosterberg]

It's <2 months old. No updates applied. It was installed 4 days after being received.

Can you try opening http://10.32.150.208/ in any web browser to see if you pick up the GEM page.

Given 1461 is open can you try the GEM Network Utility to see if you can pick up the module? 1461 is used to program the module.

Set a statc IP if so.
