FICON PCB Jumpers
Before installing the FICON interface PCB you should check to ensure that the
jumper related to each interface is installed correctly. Each FICON interface has a
jumper associated with it (P0_JX, P1_JX, P2_JX, or P3_JX). The normal jumper
setting for each jumper is in the 1-2 (F100) position.
