Replacing the Power backplane
The Power backplane is mounted on the PS cage. The power cables are
permanently connected to the Power backplane.
Ê
Open the server as described in the
section “Preparation” on page 17
Ê
Push the green latch of the hot-plug power supply unit upward and pull the
power supply unit simultaneously out of the PS cage using the handle (see
also the Operating Manual).
Ê
If a second hot-plug power supply unit has been installed, remove this one
in the same way (if there is a dummy cover instead of a second hot-plug
power supply unit, this can remain in place).
I
The Power backplane in the floorstand model is positioned directly under
the top cover and it makes sense to lay the server on a table with the
uncovered side facing upward. Place the server in such a way that the
feet can project over the edge.
Ê
Remove all power cables from the system board and the drives (see the
cabling plans in the Appendix of the Options Guide).
Figure 8: Removing the Power backplane
Ê
Remove the knurled screw (see the circle).
Ê
Push the Power backplane downward (see direction of the arrow) until it
disengages from the three bolts of the PS cage. Take out the Power
backplane.
