My X3 seems to have a problem. Every 24-48 hours one of the two units stops mining. Always the same unit.

The PSU and NIC LEDs look normal, the fans are running, and the blue "heartbeat" LED visible through the left front fan is blinking as normal.

So far as abnormal LEDs, there are yellow LEDs visible through the rear fans (I assume these LEDs indicate that the hashing modules are idle), and the blue activity LEDs on the front do not blink as the normally do when mining.

The unit is unresponsive on the network. It does not respond to ARP requests, and of course is equally unresponsive to ICMP pings and HTTP(S) requests (since those require ARP to work).

Yesterday I swapped the PSUs between the two units. The problem did not follow the PSU. The same miner still has the same problem.

Sad

(Both units are running software V1.8.)

Bogart I am not doubting your network, I am assuming you replaced the network cable on the faulty machine, and changed ports on your switch already. Also, set up a ping watcher for the machine and watch the results for when it falls off.. this will tell a lot.

I tried swapping cables/switch ports, but that did not help matters.

Unfortunately I have a new problem now. One of the power supplies seems to have died. When powered-up the red and yellow LEDs come on briefly and then go out, and then repeat about every half second.

I tried swapping PSUs, and the problem does follow the PSU this time.

I also tried powering it using 120V instead of 240V as normal. This lengthens the cycle time to about 2 seconds, but does not cause it to power on as normal.

I also tried powering it up outside of the miner with no load, but the behavior is the same.

The sticker on the PSU says it's "Sunshine Electronics model AP188".

I guess I'll try contacting BA and hope they will replace it under warranty. It ran for 13 days before dying.
