Connecting secondary interface cables

Use the Ethernet interface ports on the back of the storage server to connect the
controllers for direct management of the storage subsystems (see 32). Connect a
pair of Ethernet cables from the storage-management station to the Ethernet ports
for Controller A (located on the left) and Controller B (located on the right) on the
back of the storage server. Figure 45 shows the location of the ports.

Power cabling

The storage server uses two standard power cords. You can connect the power
cords to a primary power unit inside the rack, such as a properly grounded ac
distribution unit, or to an external source, such as a properly grounded electrical
outlet.
If you have not already done so, attach the power cords by using Figure 46 on
page 51 for the location of the component parts.
