Setting data transfer rates on host-side mini hubs
To set the Link Rate Interface switch on the host-side mini hubs, complete the
following steps.
Note: Host-side mini-hub ports must be connected to devices that have the same
1. Verify the data transfer rate of the devices on the loop or the Fibre Channel
2. Set the data transfer rate on the host bus adapter based on the data transfer
3. Set the Link Rate Interface switch to match the data transfer rate of the host
Setting data transfer rates on drive-side mini hubs
On the drive-side mini hubs, set the Link Rate Interface switch to 2 Gb per second
or 1 Gb per second based on the data transfer rate of the drive enclosures.
Note: All drive enclosures on the loop and drive-side mini-hub ports must be
To set the data transfer rate on drive-side mini hubs, do the following:
1. Verify the data transfer rate of the drive enclosure on the loop.
2. Set the link rate interface switch to match the data rate of the drive enclosure.
Connecting Ethernet cables
To manage a storage subsystem using the direct (out-of-band) method, connect a
pair of Ethernet cables from the management station to the Ethernet ports for
Controller A or Controller B on the back of the FAStT700 Storage Server. For an
illustration of direct (out-of-band) management, see Figure 5 on page 9.
Figure 40 shows the location of the Ethernet ports.
