Figure 61. Lifting the system backplane out of the system
i) Place the system backplane on an appropriate ESD surface.
24. Replace the fan socket on the right side of the bulkhead on the system backplane you just removed:
a) Insert the socket tabs into the bulkhead.
b) Slide the socket to the side to fasten it to the bulkhead.
c) Ensure that the pin clicks into place to secure the socket to the bulkhead.
25. Set the new system backplane on the ESD surface next to the system backplane you just removed.
26. Remove the fan socket from the right side of the bulkhead on the new system backplane:
a) Pull out the release pin towards the front of the system.
b) Slide the fan socket to the side to release it from the bulkhead.
27. Transfer the memory modules and fillers to the new system backplane:
a) Unlock a memory module or filler from its connector by pushing the locking tabs away from the
module in the direction that is shown in the following figure.
The lever action of the tabs pushes the memory module or filler out of the connector. If you find it
difficult to open the tabs with your fingers, you may use the tips of ball point pens or the eraser
ends of pencils to open the tabs. The levers must be opened simultaneously, so that the memory
module lifts straight up.
