To select the required SCSI ID via the 68-pin auxiliary connector (only for the 68-pin connector
disk type):
1. Verify that the SCSI ID DIP switches are set to SCSI ID 0.
2. Position the SCSI ID jumpers of the auxiliary connector to SET, according to Table 35.
11.5.2.
The SCSI bus must be terminated at the two physical ends of the cable. Only the devices
connected at either end may supply terminations. Devices that are not located at the ends of the
cable must have their terminations disabled, or they will cause a degradation of the signal
quality. Too many terminations will cause intermittent errors or other problems when accessing
devices on the SCSI bus. To select the termination condition, place a jumper between positions
9-10 of the header.
For the 68-pin connector, termination is also available via the auxiliary connector, as described
in Table 34 and Table 35.
Note: According to the SCSI standard, termination for the 80-pin SCA-2 connector must be
11.5.3.
When a jumper is placed between pins 11-12 of the header, the SSD forces a Single-Ended (SE)
electrical interface. When the jumper is removed, the SSD monitors the variation in the SCSI bus
signal for operation in either SE or Low Voltage Differential (LVD) mode.
11.5.4.
When a jumper is placed between pins 13-14 of the header, the SSD is write protected.
11.5.5.
When a jumper is placed between pins 15-16 of the header, the SSD erases the media.
Note: In Secure Erase mode, the SSD erases the media even if a write protect jumper is present.

supplied from outside the disk drive. However, for convenience, termination has been set
as an option in the SSD 80-pin model.
