M2488 PRODUCT GUIDE

The product serial number field contains 16 bytes of ASCII data that is vendor-specific. The product serial number is stored in NVRAM and is maintained across power cycles and resets. If the product serial number is not available due to a NVRAM error, then ASCII spaces (20h) are returned in this field.

1

For each of the following operating definition fields, there is a corresponding

 

 

 

SavImp (Save Implemented) bit. A SavImp bit set to one indicates that the corre-

 

 

 

sponding operating definition parameter can be saved.

 

 

0

A SavImp bit set to zero indicates that the corresponding operating definition

 

 

 

parameter cannot be saved.

0-6

03h

The default operating definition field indicates the value of the operating definition

 

 

 

the target uses upon power-up. The current and default operating definitions are

 

 

 

always reported as 03h (SCSI-2 operating definition).

 

 

 

 

6-9

Reference the Change Definition SCSI command specification (CDB byte 3) for a

 

 

 

description of the supported operating definitions listed in this page (i.e. 00h, 03h,

 

 

 

40h, and 41h).
