Starting again…

It took almost 6 hours, but the servers are now reinstalled and stable, and the network switch has been replaced.

The loading process worked fine if the machine had only 1 NIC which most did, but for the two with 2 NICs they had to be done semi-manually.

22 of the 24 servers are made of the same components, and they started crashing every 10 minutes when the kernel tried to turn the screen off to save power, but with no screen attached the system freezes.

Eventually a solution was found:

An(other) option is to disable the framebuffer support by adding theĀ nomodeset kernel option in/etc/default/grub:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

The box has been up for more than an hour since disconnecting the display now.
