Hardware Quick Reference
LANCOM 1900EF
Mounting & connecting
➀ WAN 1 interfaces (SFP / TP combo port)
Insert a suitable SFP module (e.g. 1000Base-SX or 1000Base-LX) into the SFP port. Choose a cable compatible with the SFP module and connect it as
described in the module’s documentation. SFP module and cable are not included.
If desired, alternatively connect the WAN 1 TP interface to a WAN modem using the provided Ethernet cable with green connectors.
➁ WAN 2 interface (TP)
Connect the WAN 2 interface to a WAN modem using the provided Ethernet cable with green connectors.
➂ Ethernet interface
Use the cable with the kiwi-colored connectors to connect one of the interfaces ETH 1 to ETH 4 to your PC or a LAN switch.
➃ Configuration interface
To configure the device via the serial interface, a serial configuration cable is required (available as an accessory).
➄ USB interface
You can use the USB interface to connect a USB printer or a USB storage device.
➅ Power connector and grounding point (device back side)
➆ Supply power to the device via the power connector. Please use the IEC power cable supplied (separately available for WW devices).
ATTENTION: High touch current possible! Connect to earth before connecting the power supply.
Before initial startup, please make sure to take notice of the information regarding the intended use in the enclosed installation guide!
Operate the device only with a professionally installed power supply at a nearby power socket that is freely accessible at all times.
Please observe the following when setting up the device
- The mains plug of the device must be freely accessible.
- For devices to be operated on the desktop, please attach the adhesive rubber footpads
- Do not rest any objects on top of the device and do not stack multiple devices
- Keep all ventilation slots of the device clear of obstruction
- Mount the device into a 19” unit in a server cabinet using the provided screws and mounting brackets. Pay attention to the “R” and “L” marks on the brackets for accurate mounting.
