•
Connect the hose cable from the local I/O riser ports to the remote risers
in the PCI box (Figure 2–7).
NOTE : When the system is upgraded to two system boxes, only the power cable
and the signal cable of the second system box need to be attached to the
power cabinet. Also, for this upgrade, the distribution board must be
replaced with a hierarchical switch. See the AlphaServer GS160/320
Upgrade Manual.
7. Connect the system ground wire (Figure 2–6) from the power cabinet to
the system cabinet as follows: remove the M5 Phillips screw from the
system cabinet, attach the loose end of the ground wire, and secure it to the
system cabinet with the screw.
8. Make the OCP connections to the PCI box and the power subrack.
•
Connect the signal cable from the J2 connector of the OCP to the first
PCI box J3 connector
(
Figure 2–8
)
.
•
Connect the power cable of the OCP
(
Figure 2–8
)
to the first power
subrack. The OCP end of this power cable is connected to the J1
connector of the OCP, while the power subrack end
is attached to
connector J12. This end of the power cable is daisy-chained to additional
power subracks in system upgrades.
NOTE: If your system comes with two system boxes (blue and green), then a
hierarchical switch will have been attached to system cabinet 1 instead
of the distribution board. In such a case, you must connect the CSB
cable from the H-switch to the CSB adapter and terminator on the
power cabinet. You must make power and signal connections to system
box 2 (Figure 2–6). In addition, you must make the OCP power
connection to the J12 connector of the second (green) power subrack
(
Figure 2–8
).
