Connecting a VSN900X Expansion Chassis
If your expansion chassis is supplied as part of a wall controller system the HLink-G3 card will be
pre-installed in the host machine which contains the SBC. If the expansion chassis has been
supplied separate to a host machine the HLink-G3 card provided needs to be installed in the host PC.
You are likely to need a flat blade and/or a cross head screwdriver for the installation of the HLink-G3 card;
it would be useful to have these to hand before you begin. Power down the PC (including peripherals),
switch off at the mains and disconnect all the cables connected to the computer and expansion chassis.
Remove the PC cover. Locate a vacant PCIe slot (x8 on the motherboard and remove the backing plate
(retain all screws) .
Remove the HLink-G3 card from its packaging and secure it firmly into the empty PCIe slot. Screw the
bracket to the back panel of the PC and replace the cover.
Connect the HLink-G3 and SLink-G3 using the ExCable-G3 provided. If more than one expansion chassis is
supplied, ensure the cards are paired correctly by connecting the cards labelled “Link1” together, the pair
labelled “link2” are connected together and so on. In the event that this is not possible i.e. the expansion
chassis are shipped separately and the cards are not labelled, connect the cards using the ExCables-G3
provided and re-install the Datapath Driver Install package to reset the pairings.
