Removing from the S7-300 rail
To remove the device, you require a slotted screwdriver with a 5.5 mm wide blade.
Notice
When removing the SCALANCE X414-3E, hold it by the backplane and not by the
modules, otherwise the device may be damaged.
To remove the device, follow the steps below:
1. Remove the covers from slots 7 and 9 (see section 6.2.2) and the dummy
cover from slot 8 (see section 6.2.3). If media modules are inserted, remove
the fast Ethernet media module instead of the cover from slot 7 (see section
6.2.1).
2. Using a screwdriver with a 5.5 mm wide blade, loosen the two captive screws
in the backplane at slot 7 and between slots 8 and 9.
3. Pull out the lower part of the basic device slightly towards the front and lift it
from the S7-300 rail.
