7.8 Option jumper block
As shown in the figure below, the 80 pin SCA-2 card has a single jumper block ( J6). The 68 pin card contains two jumper
blocks (J4 and J6).
J4 and J6 have 14 positions numbered #1 - #14.
As described in Section 7.7, “Auxiliary connector on 68-pin model” on page 33, some of the jumper pins on J4 of the 68-pin
models can also be controlled through the Auxiliary Connector. These controls work as logical OR between the Option Jumper
Block and the Auxiliary Connector.
As described in Section 7.2.2, “SCSI signal connector (80-pin SCA-2 model)” on page 31, some of the jumper pins on J6 of
the 80-pin models can also be controlled through the 80-pin SCA-2 connector. These controls work as a logical OR between
the Option Jumper Block and the SCA-2 connector.
