Install the screw that passes through the supercap power module (backup battery) cover.
Remove the protective tape from the thermal interface that is on the underside of the heatsink.
Align the heat sink assembly and its two captive screws with the holes in the controller card.
Tighten the two captive screws to the two standoffs that are under the controller card.
With the two ejector levers open, align the new server node with the empty bay.
The server node must be in the top bay, as shown in
Push the server node into the bay until it engages with the midplane connectors and is flush with the
