● For devices with power supply unit 24 to 48 VDC: Limit voltage = 17 VDC
● For devices with a multiple range power supply unit 100 to 240 VAC / 60 to 250 VDC:
Note
Devices of the X‑300EEC product group
When using only one power supply unit 24 VDC and two 24 VDC power supplies, the LEDs "L1"
and "L2" signal the existence of the power supply L1 and L2.
When using two 24 VDC power supply units, the LEDs "L1" and "L2" signal the existence of the
primary voltage and the secondary voltage for both power supply units. If the power supply is
intact, a fault occurring on a power supply unit on the secondary side can be recognized.
The P1, P2, ... LEDs for the port status
The P1, P2, ... LEDs show information on the status of their port (transmission speed, mode,
port monitoring). The meaning of these LEDs depends on the display mode ("DM" LED).

V * , the signaling contact responds.
)
Power supplies L1 and L2 are not monitored. If L1 or L2 falls
below 17 V, the signaling contact does not respond.
Power supply L1 or L2 is monitored. If L1 or L2 falls below 17
V, the signaling contact responds.
Power supplies L1 and L2 are monitored. If L1 and L2 fall
below 17 V, the signaling contact responds.
Meaning
No valid link to the port (for example station turned off or
cable not connected).
Link exists and port in normal status. In this status, the port
can receive and send data.
Link exists and port in "blocking" status. In this status, the
port only sends and receives management data (no user
data).
tus, no data is sent or received via the port.
the data traffic of another port is mirrored to this port.
Receiving data at port.
With SCALANCE X-300 devices, both the receipt and the
sending of data is indicated for the optical gigabit ports.
