The following applies to the X-300EEC:
For devices with power supply unit 24 to 48 V DC: Limit = 17 V
For devices with a multiple range power supply unit 100 to 240 V AC / 60 to 250 V DC:
Limit voltage = 46.5 V DC or 80 V AC
Note
Devices of the X-300EEC product group
When using only one power supply unit 24 V DC and two 24 V DC power supplies, the LEDs
"L1" and "L2" signal the existence of the power supply L1 and L2.
When using two 24 V DC 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 respective ports (transmission
rate, mode, port monitoring). The meaning of these LEDs depends on the display mode
("DM" LED).
Meaning in display mode A
LED color LED status Meaning
- off No valid link to the port (for example station turned off or
cable not connected).
on Link exists and port in normal status. In this status, the port
can receive and send data.
flashes once per period Link exists and port in "blocking" status. In this status, the
port only receives management data (no user data).
flashes three times per
period
Link exists and port turned off by management. In this status,
no data is sent or received over the port.
green
flashes four times per
period
Port exists and is in the "monitor port" status. In this status,
the data traffic of another port is mirrored to this port.
yellow flashes / lit Receiving data at port.
With SCALANCE X-300 devices, both the receipt and the
sending of data is indicated for the optical gigabit ports.
