4.4 Replacing the Power backplane
Ê Open the server as described in the section "Preparation" on page 23.
Ê Remove the system fan 2&4 and the system fan 1&3 as described in the
section "System fans" on page 25.
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
the Operating Manual).
Ê If a second hot-plug power supply unit has been installed, remove this one
in the same way (an installed dummy cover can rest 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.
Ê Disconnect all power cables from the Power backplane.
Figure 10: Removing the Power backplane
