	2. Make sure the libraries, Fibre Bridge, and hubs (DLT only) are
	powered on and connected appropriately before powering on
	workstations. If they were not connected, powered on, and configured
	properly before the NT workstation was powered on, restart the
	workstation (and any other on the loop, one at a time) so they can
	re-discover the library.

NOTE	(DLT Only) Do not restart multiple NT workstations on a Fibre Channel
	loop at the same time. Allow each workstation to complete the process
	and display the NT login prompt before turning on the next computer. If
	more than one workstation is powered on at the same time, only one will
	locate devices on the Fibre Channel loop. This sequential process is
	particularly critical when recovering from a power failure.
