Creating the Link - "x8"

For maximum bandwidth, the HLink \SLink -Optical cards should be connected using two optical

cables to form an eight-lane ("x8") link, capable of 64G-transfers/sec (approx 6.4GB/s effective data rate in

each direction.

In "x8" mode the Jumper Link "J7" must be set to position 2-3 as shown in Fig.9.

When creating the "x8" link, the ExCable-Optical connected into the top connector on the HLink-Optical

card must also be connected to the top connector on the SLink-Optical card. Similarly the second

ExCable-Optical must connect between the lower card connectors.

Creating the Link - "x4"

For a reduced bandwidth connection or where a single HLink-Optical is used to connect to two separate

SLink-Optical cards (i.e. "Star" connection of two expansion chassis). In this configuration, for a single

ExCable-Optical link the PCIe connection is "x4" and the bandwidth is reduced to 3.2GB/s.

In "x4" mode the Jumper Link "J7" must be set to position 1-2 as shown in Fig.11.

Either (or both) connectors on the HLink-Optical card can be used, but only the top connector of the

SLink-Optical card (see Fig.12).
