Xserve (Late 2006) Logic Board Replacement Instructions 5
FB-DIMMs
Push down the ejectors on the FB-DIMM slot.
Holding the FB-DIMM by both top corners, lift it straight up out of the Xserve.
Repeat for the other installed FB-DIMMs.
Important: The order of the FB-DIMMs in the slots can affect performance. Unless you are
sure that all the FB-DIMMs are identical, keep track of which slot you remove each FB-DIMM
from so you can return it to the same slot on the replacement logic board.
Connectors Notch Ejectors
Warning: When removing or installing the FB-DIMM, handle it only by the edges. Do not touch
its connectors. Lift the FB-DIMM straight up from the connector to remove it, and insert it straight
down into the connector to install it. Do not rock the FB-DIMM from side to side.
