OPERATING THE JUKEBOX
The jukebox controller uses two SCSI IDs if your jukebox has one drive and three IDs if your jukebox has two drives. The jukebox controller is assigned one ID and one ID is assigned to each disk drive. The default SCSI IDs are as follows · jukebox controller = 3 disk drive 1 (lower drive) = 4 disk drive 2 (upper drive in a two-drive model) = 5 If you are already using one of these IDs for your host bus adapter or another SCSI peripheral device, follow the directions in one of the next two sections to change either the jukebox controller or a drive ID.

OPERATING THE JUKEBOX
NOTE: CONFLICT displays if you attempt to set the jukebox controller and a drive to the same ID. Repeat the procedure and
reset one of the IDs to another, non-conflicting ID.
NOTE: After you change an ID you may have to restart your host computer for the new ID to be recognized.
Caution: Do not turn power to STANDBY in this jukebox until you are sure the SCSI bus is inactive. Removing power from a SCSI
peripheral when the bus is active can result in data loss and/or indeterminate bus states. Check your host system manuals for information about checking the SCSI bus status.
7. Switch the jukebox standby/on switch to STANDBY, the back to ON to save the new SCSI ID in jukebox memory.

front panel The part of the jukebox that includes a control panel used to manage and display functions, and a mailslot to insert and remove disks. high-voltage differential SCSI Signals are asserted on the bus by using two lines for each signal and measuring the voltage difference between the signals. Differential retains more signal quality than single-ended and is not as sensitive to noise, allowing for a longer cable length. HVD See high-voltage differential SCSI.
