6.1.1 Installing / Uninstalling with an S7-300 Rail
Installing on an S7-300 Rail
For installation, you require a slotted screwdriver with a 5.5 mm wide blade.
Notice
When installing the SCALANCE X414-3E, hold it by the backplane and not by the
modules, otherwise the device may be damaged.
To install the device, follow the steps below:
1. Tilt the basic device slightly towards the back with the upper groove on the
edge of the S7-300 rail and push in towards the bottom. In this position, the
basic device should not slip off but it can be adjusted horizontally to the left or
right until the required position is achieved.
2. 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).
3. Using a screwdriver with a 5.5 mm wide blade, tighten the two captive screws
in the backplane at slot 7 and between slots 8 and 9 until the basic device can
no longer be moved to the side.
Note
Only horizontal installation permitted (ventilation slit top/bottom).
