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 a PE jumper installed. |
SS |

|
Off/On | Reserved. Default is no jumper installed. | |
TP | TP |
|
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 for "N" |
|
| models only. |
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. |
