PE

 

 

 

On

 

Parity checking and parity error reporting by the

 

 

drive is enabled.

 

Off

 

Drive does not report result of parity checking to

 

 

host. Default is no PE jumper installed.

 

TE

 

(Applies to "N" and some "NC" models only)

On

 

With the jumper installed, the On-board (non-

 

 

removable) terminator circuits are enabled (con-

 

 

nected to the I/O lines). Default is jumper in-

 

 

stalled.

 

Off

 

Terminator circuits not connected to I/O lines.

TP

TP

(Not used on "NC" drives not having U5 on

 

 

PCB)

 

Off

Off

No terminator power is connected to drive termi-

 

 

nators or SCSI bus I/O pin 26.

 

On Off

Drive supplies its own terminator power only.

 

 

Jumper on this position is factory default.

 

Off

On

Drive supplies power to I/O pin 26 of SCSI bus;

 

 

none to internal terminators. When drives have

 

 

differential I/O circuits, a jumper on the right TP

 

 

position may be needed to power external termi-

 

 

nators (see system documentation). The "ND"

 

 

model drives have differential I/O circuits which

 

 

have no terminator circuits on the drive.

 

On

On

Drive supplies terminator power to itself (internal

 

 

connection) and to I/O pin 26 of SCSI bus. This

 

 

is a legal jumper setting.
