Hi Guys

We had a CCR10009-8G-1S-1S+ used as a PPPoE concentrator. Nothing too complex. We got a network alert through saying it had died and low and behold, the unit had no lights on it despite being powered through power 1. Tested the power supply (from an APC UPS) and it was working fine. Tried to power the unit through PSU 2 and the unit still doesn't power up. We RMAd the unit and Mikrotik replaced it under warranty.

The replacement arrived last week so we plugged it in again and now the same fault has happened. Really not sure what's going on but the power supply from the APC UPS isn;t showing any spikes and we have 10+ CCR1036 in the same rack acting as provider edge routers.

Are these units painfully unreliable or are we doing something wrong here?

I can't get the support files as they're now toasted but when they rebooted just before they died, I could login and the log file had no mention of the reboot in it but system -> uptime showed uptime of 1 min before it finally died for the last time.

Both PSUs fail to power the unit so it looks lie the board itself.

You are not the only one.

I'm interested in buying one CCR10009-8G-1S-1S+ but now is in standby.
I hope an official clarification on this matter before buying one.

We just lost 2 back-to-back that came in on the same order. They both were deployed in late February and died in early April within 2 days of each other. MAC addresses are only a few numbers apart. Both in air-conditioned, raised-floor data center environments. Have several in much harsher conditions that are still ticking, and quite a few other CCR models that have been chugging along for at least a year now.

Power supplies working but board wouldn't power up. Mikrotik is replacing under warranty but has been silent when asked if this was an ongoing issue. We have about 6 other CCR1009-8G-1s-1s+ deployed. Crossing my fingers. Plenty of other CCR routers deployed with no issues. Only the 8g-1s-1s+ have died, and only 2 out of 8, but 2 very close to each other in serial numbers/mac addresses.

Maybe we can track down what mac address/serial number ranges are the bad ones?

These ended in C5:99:36 and C5:99:72.

It would be nice if Mikrotik could identify the bad batch and they could be replaced proactively instead of scrambling at 03:00 when your monitoring system starts screaming that your routers are down. We almost lost a large contract over these.

So far with my personal experience with two CCR 1009 had no problem so far, I've replaced with two old cisco with two CCR 1009 just a two months ago and they have been working fine since then hope they continue to do so
