I just replaced some old servers at a colo site with IBM 3550's with no
PS/2 connectors and found that the usb adapter we used works with an
old keyboard/mouse connected directly but did not work with the KVM that
was there. This particular kvm won't let you select a port without a
computer connected so we had to leave the adapters connected to even be
able to view the monitor output as they booted up. Fortunately the
machines had been pre-configured and subsequent management will bed done
over the network anyway so it won't matter too much.
