Safety notices on the use of the device
The following safety notices must be adhered to when setting up and operating the device
and during all associated work such as installation, connecting up, replacing or opening the
device.
General information
WARNING
Safety extra low voltage
The equipment is designed for operation with Safety Extra-Low Voltage (SELV) by a
Limited Power Source (LPS). (This does not apply to 100 V...240 V devices.)
This means that only SELV / LPS (Limited Power Source) complying with IEC 60950-1 / EN
60950-1 / VDE 0805-1 must be connected to the power supply terminals. The power supply
unit for the equipment power supply must comply with NEC Class 2, as described by the
National Electrical Code (r) (ANSI / NFPA 70).
There is an additional requirement if devices are operated with a redundant power supply:
If the equipment is connected to a redundant power supply (two separate power supplies),
both must meet these requirements.

3.4 The SET / SELECT button
SCALANCE X-300M
16 Compact Operating Instructions, 10/2014, A5E02630801-06
3.4
The SET / SELECT button
The SET/SELECT button is located on the top of the housing of devices of the X-300 EEC
series. On all other devices, this button is on the front panel of the housing beside the LED
display. The SET/SELECT button has several functions that are described below.
Change the display mode
By pressing the button briefly, you change to the display mode of the LED display. For more
detailed information on this topic, refer to the section "LED display".
Resetting the device to the factory defaults
If you reset, all the changes you have made will be overwritten by factory defaults. Follow the
steps outlined below:
1. Turn on display mode A. Display mode A is active when the "DM" LED is not lit. If this
LED is lit or flashing, you will need to press the SET/SELECT briefly (possibly several
times) until the "DM" LED goes off. If the SELECT/SET button is not pressed for longer
than a minute, the device also turns on display mode A.
2. Hold down the SELECT/SET button for 12 seconds. If you release the button before the
12 seconds have elapsed, the reset is canceled.
Definition of the fault mask
Using the fault mask, you specify an individual "good status" for the connected ports and the
power supply. Deviations from this status are then displayed as errors/faults.
1. Turn on display mode A or D. Display mode A is active when the "DM" LED is not lit.
Display mode D is active when the "DM" LED flashes yellow/orange. If a different display
mode is active, you will need to press the SET/SELECT briefly (possibly several times)
until the required display mode is active.
2. Hold down the SET/SELECT button for five seconds. After three seconds, the "DM" LED
begins to flash. If you release the button before the five seconds have elapsed, the
previous fault mask will be retained.
Enable/disable the redundancy manager
1. Turn on display mode B. Display mode B is active when the "DM" LED is lit green. If a
different display mode is active, you will need to press the SET/SELECT briefly (possibly
several times) until display mode B is active.
2. Hold down the SET/SELECT button for five seconds. After three seconds, the "DM" LED
begins to flash. If you release the button before the five seconds have elapsed, the action
is aborted.
3. The result of the action depends on the initial situation:
–If the redundancy manager and media redundancy were disabled, media redundancy
is also enabled after enabling the redundancy manager.
–If you disable the redundancy manager, media redundancy remains enabled.
