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).
