Note: Your Linux operating system may not support SES but the SES

functions are used when running the standalone AIX Diagnostic CD.

Attention: The SCSI address of the SCSI attachment that is connected to the

2104 must be different from the addresses of the installed disk drive modules.

When a second SCSI attachment is connected to a 2104, the SCSI address of

that SCSI attachment must be different from the address of the first SCSI

attachment and different from the addresses of the installed disk drive

modules.

 

12. The 2104 Orientation switch 2 configures the Power and Check lights that

 

are on the front of the 2104. Ensure that this switch is set to Off so that the

 

lights are correct for your 2104 Model DU3.

 

13. The SCSI Bus Split switch 3 controls the SCSI bus configuration of your

 

2104. When the switch is set to Off, the 2104 is configured in single SCSI bus

 

mode. When the switch is set to On, the 2104 is configured in dual SCSI bus

 

(split bus) mode.

When a 2104 Model DU3 is in dual SCSI bus mode, the SCSI addresses of

one SCSI bus are 0 through 6, from left to center, and the SCSI addresses of

the other SCSI bus are 8 through 14, from center to right.

Refer to the 2104 configuration information, and set the SCSI Bus Split switch

3 as required.

 

14. Switch 4 is reserved. Ensure that is it set to Off.
