19" rack mounting
1. Select the required rack device and the 19" cabinet.
2. Fix the two mounting brackets with 4 screws each to the
sides of the housing. The maximum tightening torque for
these screws is 0.5 Nm.
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 noth-
ing 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 con-
nector is on the rear of the device between the power
connectors.
5. Fit the connectors for the power supply.
Note that the SCALANCE X-300 is available for different
power supplies (100 to 240 VAC and 24 VDC 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).
