3. Fasten the three screws and nylon washers that secure the backplane to the disk
cage.
If you are installing the expansion backplane for the first time, the nylon washers are
included with the backplane kit.
4. Connect the expansion FC-AL backplane cables to the backplane.
If you are installing an expansion backplane in the system for the first time, install
the following cables:
a. FC-AL data cable (A and B) to connectors A(J0201) and B(J0200) on the
expansion backplane and to connectors F(J0501) and E(J0500) on the base FC-AL
backplane
b. Base/expansion cable (P42) to the power distribution board at connector
P42/J7(DISKS)
Note – The expansion backplane cable is routed to both FC-AL backplanes. The
cable end and connector that goes to the base backplane connector (J0801) will not
reach the upper backplane. The two cable ends ganged together go to the upper
backplane at connectors J0801 and J0100.
