Dead WS-26-400-AC

We have an un-responsive 26 port switch, quit suddenly - reason unknown, device runs on pure sine inverter on a large battery bank
Before trying firmware recovery, I wanted to try and get the LOG file out of it via the console port
Can you give me instruction on the command and steps for this

Further to the switch being dead, I powered it up with a serial cable and a terminal program on my PC
It shows "Segmentation Fault", many of them until I hit Ctrl C
Then shows @OpenWrt:/# prompt
I measured the DC supply to the switch board, shows 50.3vdc
The PC board is version D
typing in help shows the commands, nothing evident about reading the LOG
How can I read the LOG file from the console port ?

We have the same problem. I am glad someone got back to you.

To the best of my knowledge log files don't survive a reboot.
So I'd just go down the firmware recovery route and see if that fixes it.
