2.1.3 Backplane SHELF_OK Jumper
As shown in Figure 2–1, the SHELF_OK connector (J17), located on the
backplane adjacent to slot 2 (J12) behind the left-hand blower, has two pairs
of jumper pins. Placement of jumper W1 on these pins determines whether the
SHELF_OK signal is:
• Routed to the upper external cable connector (JA1 and JB1)
• Routed to slot 0
Figure 2–1 and Table 2–1 describe the proper use of the SHELF_OK jumper W1.
