Server resume after modem blip

Channels DVR Server
#1

Hi all. Maybe this scenario will sound familiar enough that someone can guide me.

I have Channels DVR set up on a Mac Mini, Been running it for a few months and it is very stable. The Mac is hooked up to my Sony OLED as a monitor, and it and all peripheries are hooked into a UPS for any power blips we might have (we have a lot here in Monterey). I've pretested, and I can run the kit for almost two hours with no power, at which point I have things configured to gracefully shut down/restart.

Today, I had a ten minute outage, and everything stayed on – except for my AT&T router/gateway, which is in the next room and unUPS'd. The power returned and the Mac/TV etc. had no idea the power was interrupted. Except, of course, it had lost internet for that period of time.

When power returned, I checked everything, and the server admin page would not load locally or remotely. I jabbed at the "restart server" meny item, that did nothing.

I then restarted the machine and everything was fine. So, I am worried I might not have a graceful restart in this case if I am away from the server or house for a few days to be here to restart things.

Anyone think of some step I missed in terms of powerproofing or configuring my setup?

Thanks!

Check the DVR log for errors during that time frame.

What and where is the "restart server" menu item?

I looked at the logs. I see nothing in the logs past last night when the server did some trash cleanup. Power went off at 7 am, back on at 7:10. I just couldn't load the server monitor/config web page so I felt something was wrong. The next logged actions were due to my restarting the entire machine.

When you tried to view the DVR admin page from a browser, were you using a bookmark?
If so, what is the url in the bookmark?
Thinking network/dns issue since your router rebooted.

Sounds like you need an ups on your router. For about 80 bucks, you can pick up an APC BE600M1 which should run your router for a couple hours.

Agreed. This will probably work in a situation where the modem never runs out of UPS. I'm thinking of a more likely case, where power goes out for a longer period, the modem goes dark, power comes on, modem gets a new handshake, and.... I am here again. It's a step in the right direction tho. Thanks.

My channels bookmark is pretty plain. My IP address is static. 192.168.1.107:8089/admin/settings/status

Could always add a bookmark to Safari on the Mac Mini running CDVR.
http://127.0.0.1:8089

How would this local url be any different that what I normally use, the static IP of the machine?
192.168.1.107:8089

Only difference is 127.0.0.1 doesn't go though the NIC interface and doesn't depend on an IP address assignment, whether Static or DHCP assigned.

Thanks. I will try this the next time I get into this.

I use a Belkin residential gateway battery backup on mine. Check Ebay for them. They are a 12vdc UPS system made for exactly this job. Model number: BU3DC001-12V
