If Necessary, Remove the Termination Resistors

If the SCSIAdapter is installed in the middle of a SCSIbus, that is, not at the end as shown in figure 1 on page 12,the termination resistors on the SCSIAdapter should be removed. (This would only occur in an HA solution with greater than two CPUs, or if a V cable is used.) Seefigure 3 for the locations of the termination resistors (remember, the component locations on the two adapters are identical except for the front faceplate).
