Installation
5.4 Installing a switch
19" rack mounting
CAUTION: If you install a rack device with components
inserted.
The locking mechanisms of components installed in the
rack device (for example the handles of media modules or
the clips on the SFP) must be closed.
See also installation of modular devices:
- Installing media modules in a slot
- Installing an SFP in an SFP media module.
3. Insert the rack device in the 19" cabinet and hold the rack
device at the required height. Make sure that nothing is
obstructing air from entering the ventilation grilles.
Fit the securing screws to the two mounting brackets to
secure the rack device in the 19" cabinet.
4. Connect the grounding bolts. On the SCALANCE
X-300EEC, the PE connector is on the bottom of the de‐
vice. On the SCALANCE XR-300M EEC, the PE connec‐
tor is on the rear of the device between the power con‐
nectors.
5. Fit the connectors for the power supply.
Note that the SCALANCE X-300 is available for different
power supplies (100 to 240 V AC and 24 V DC variants).
6. Fit the remaining connectors, for example the signaling
contact.
Removal
Removing from the rack
1. Turn off the power supply for the SCALANCE XR-300M.
2. Disconnect all cables for data traffic and the connectors for the power supply and the grounding cable.
3. Undo the screws on the mounting bracket and remove the rack device from the 19" cabinet.
If necessary, release the locking mechanisms of components inserted in the rack device (for example handles on the
media module or clips on the SFP) to be able to remove the media modules (MM900) or the transceiver (SFP).
