11. Each disk drive module is identified to the using system by a SCSI address. | |||||||||||||||||||
| This address is related to the slot in which the disk drive module is installed. | ||||||||||||||||||
| The SCSI address switch 1 must always be set to the Off position. |
|
|
| |||||||||||||||
| Table 1 shows the SCSI addresses of the disk drive module slots. |
