Notes: |
| 1. |
40 MB/sec represents SCSI-3 fast 20 wide. |
| 2. |
The drive shall not incur damage for an over voltage condition of +25% (maximum duration of 20ms) on the 5 V nominal supply. |
| 3. |
The maximum supply ripple is measured at the 5 V input on the drive. |
| 4. |
The system is responsible for providing sufficient air movement to keep the surface temperature, measured at the center of the drive's top cover, below 60
C. |
| 5. |
Due to the complexity of this subject we recommend that users contact the distributor to discuss how to perform the required measurements if they believe
this to be an area which requires evaluation. |
