2.a. Installation and removal
1) Power down the host system.
2) Open the chassis according to your system documentation.
3) Remove the host cable adapter from the protective bag, observing proper ESD safety procedures.
2.b. Installing the host cable adapter:
1) Insert the host cable adapter into a PCIe x4, x8 or x16 add-in slot in the host motherboard. Make sure that the card is well
seated and tighten the screw on the top of the slot cover.
2) Attach the cable by first pulling back on the retractor ring. Align the keyed slot with the connector key ridge on the slot
cover. Insert the cable connector into the connector shell on the board until the connector teeth snap securely into the
holes in the cable shell.
3) The connectors on either end of the PCIe x4 cable are identical. Each connector is equipped with a retractor to allow the
connector to be locked into place.
