Problems with B3 rescue and disassembly
Posted: 26 Apr 2026, 06:26
Hi,
one of my dear B3s got unreachable after a likely misconfiguration of the network interfaces yesterday (tried to add a vlan interface).
After a few unsuccesful attempts to re-establish contact with the B3 using different rescue USB sticks, I have started suspecting a hardware failure and wanted to swap the disk with another of my B3s. But now hitting the next hurdle, not being able to get the boards+HD to slide out of the B3 chassi! I have unscrewed the four screws on the back plate and removed it, then tried to push the side locking tabs apart (and opposite way) to let the board plus front panel slide out from the the front side, but it does not come out more than 1mm.
I have once installed the disks in these B3s myself, and cannot remember having any problems with that.
Anyway, if someone has some hints for how to progress from here, would be immensly grateful!
