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.
