This applies to all media converters of the SCALANCE X-100 series.
Do not use any parts that show evidence of damage! Warning If the SCALANCE X101-1 device is operated in ambient temperatures between 55°C- 60°C, the temperature of the device housing may be higher than 70°C. The subject unit must be located in a Restricted Access Location where access can only...
4.2.3 SCALANCE X101-1 Product Characteristics Possible Attachments The SCALANCE X101-1 media converter features an RJ-45 jack and a BFOC port for the connection of DTEs or other network segments. Note The BFOC socket (Bayonet Fiber Optic Connector) corresponds to the ST socket...
Pin 3 Pin 2 Pin 1 On SCALANCE X101-1, the twisted pair port is implemented as RJ-45 jack with MDI-X assignment (Medium Dependent Interface–Autocrossover) of a network component. Notice TP cords or TP-XP cords with a maximum length of 10 m can be connected to the RJ-45 TP port.
All media converters of the SCALANCE X-100 series support the MDI / MDIX autocrossover function. 4.2.5 SCALANCE X101-1 FO Port Transmission Speed The transmission rate of the optical Fast Ethernet port is 100 Mbps. Transmission Mode The transmission mode for 100Base-FX is specified in the IEEE 802.3 standard.
(SELV) complying with IEC950/EN60950/ VDE0805 can be connected to the power supply terminals. The power supply unit to supply SCALANCE X101-1 must comply with NEC Class 2 (voltage range 18-32 V, current requirement 200 mA).
The signaling contact is connected to a 2-pin plug-in terminal block. The signaling contact (optical relay contact) is a floating switch with which error/fault states are signaled by contact separation. Figure 4-5 Signaling contact SCALANCE X101-1 Figure 4-6 Connector pinout...
Product Characteristics 4.2 SCALANCE X101-1 If an empty fault mask (no port is monitored) is set or is to be set, the 2 port LEDs flash alternatingly. Simultaneously with the fault mask, the monitoring of the connected power supply is set. The existence of the two power supply units is only monitored if both power supplies are connected during saving the fault mask.
Fault indicator (red LED) ) Status Meaning Lit red SCALANCE X101-1 detects an error. Simultaneously the signaling contact opens. The following errors are detected: 1. Link down event at a monitored port. 2. Failure of the supply voltage or supply voltage less than 14 V of one of the two redundant power supplies.
