Ultrastar 9LZX: Models DRVS-09V and DRVS-09D
Ultrastar 18ZX: Models DRVS-18V and DRVS-18D
(FC-AL models)

Ultrastar 9LZX/18ZX models contain a jumper block that can be used to enable certain features and select the SCSI ID of the drive. This jumper block is referred to as the 'Front' Option Jumper Block due to its location on the drive (opposite the SCSI connector). This jumper block varies in pin definition based on interface type (68, SCA-2).

See the following topic for additional installation information:

The 68 pin models contain an 'Auxiliary' connector that replicates some of the functions contained in the Front Option Jumper Block. Either the Front Option Block or the Auxiliary Block may be used but not both.
