Seagate ST410800N/ND, ST410800W/WD manual ST410800N/W termination

22 Elite 9 Installation Guide, Rev. B

To terminate ST410800N and ST410800W drives, en- able the permanently mounted IC terminators by install- ing a jumper on J4A pins 19 and 20 as shown inFigure 4. If you install one of these models and it is not on the end of the SCSI bus, remove internal termination from the drive by removing the Enable Drive Terminator jumper (see Figure 4). This disables the permanently mounted IC terminators.

Note. This jumper applies only to N- and W-type models.
