Quantum snc 4500 Betriebsanweisung

Each SCSI bus has its own LED to show activity on that bus. The LED blinks when I/O is occurring and is 
solid when there is heavy activity.

The Fault LED lights yellow when the SNC is turned on, then immediately goes dark. Software activates 
the LED if there is a system error.
