1. Set the P8 jumper to the appropriate position for the system configuration:
• For a system with three boards, move the P8 jumper on to pins 1 and 2.
• For a system with two boards, move the P8 jumper on to pins 1 and 2.
• For a system with one board, verify that the P8 jumper is only on pin 1.
In the following graphic, the setting on the left with pins 1 and 2 jumpered shows
bus termination set to on. The settings on the right show bus termination set to off.
2. Move the P11 jumper on the top of the board on to pins 1–2 to disable power
budgeting.
Setting the D/120JCT-LS–EW board
Prerequisites
Determine in which slot in the PCI cage you will be installing the board. Slots in the PCI cage are
number 3 (bottom slot), 4 (middle slot) and 5 (top slot). If a system has one board, install it in
slot 3 (bottom). If it has two boards install them in slots 3 (bottom) and 4 (middle). If it has three
boards install them in slots 3 (bottom), 4 (middle) and 5 (top).
For the D/120JCT-LS-EW board, set the board ID, the hook-switch state and turn off power
budgeting.
