All pins are in a single row, with a 1.27 mm (0.050") pitch. 2. The comments on the mating sequence apply to the case of backplane blindmate connector only. In this case, the mating sequences are: • the ground pins P4 and P12. • the pre-charge power pins and the other ground pins. • the signal pins and the rest of the power pins. 3. There are three power pins for each voltage. One pin from each voltage is used for pre-charge when installed in a blind-mate backplane configuration. 4. All used voltage pins (Vx) must be terminated. 4.2.1 ATA Security policy exceptions In the ATA Security Interface mode, the drive conforms to the ATA Security Policy, except the following desirable exceptions to implement the desired Momentus 5400 FDE.4 SATA behavior: Upon execution of the secure erase sequence, the drive will have the following behavior: • All secure erase modes will instantaneously delete the encryption key rendering all user data unintelligible. • A new encryption key will be generated inside the drive replacing the previous encryption key. • The new encryption/decryption key will be applied to the data for all subsequent writes/reads prior to the next secure erase sequence. • The user password will be cleared to a null value. • The master password will retain the current value per the ATA specification. Note. On completion of this sequence, the user is assured that all sectors on the drive are unintelligible and 26 Momentus 5400 FDE.4 SATA Product Manual, Rev. B
