Removing and Installing Fans
Proceed as follows to remove or install the fan:
Disconnect the cables from the monitoring module, the motherboard, and the
bus module and write down their previous connections.
Provided expansion modules are not installed or have previously been
removed, the fan cage can be taken out. First remove the two clamps of the
fan cage (see Figure 1-7) then push the top of the two side sections outward
and lift the fan cage up.
First the connecting cables have to be carefully removed from the bottom of
the cut-out, then remove the two fans.
If expansion modules are installed, you can take out the fans from the fan
cage, even without previously removing the expansion modules: first unplug
the connecting cable from the fan, then push the hook slightly backwards
(use a screwdriver), and lift up the fan.
Proceed in reverse order to install the fans.
