Connecting Expansion Chassis (VSN900X)
It is possible to connect a VSN900X expansion chassis to the VSN970 thereby increasing the number of
PCIe slots available.
The following diagram illustrate how this can be achieved:
Connect the chassis by installing HLink-G3 and SLink-G3 cards in the VSN970 and VSN900X and
connecting the two cards using the Ex-Cable-G3.
The HLink-G3 and Slink-G3 cards are factory installed into a system as a pair. When connecting
expansion chassis ensure that the pair labelled Link1 are connected using the ExCable-G3, the pair
labelled Link2 are connected together and so on. In the event that this is not possible, connect the
expansion chassis to the host machine and re-install the Datapath Driver Install to reset the pairings.

When connecting a VSN900X expansion chassis to a VSN970 machine the HLink-G3 card in the VSN970
must be installed into the x8 slot. The SLink-G3 card in the VSN900X should be installed in the PICMG1.3
SBC slot.
Connect the HLink-G3 and SLink-G3 cards using the ExCable-G3.
