Connect the power supply to a power socket using the enclosed or another suitable IEC cable or the enclosed external
power supply unit. Observe the safety instructions on the right.
This LANCOM device is subject to governmental regulation. The user is responsible for ensuring that this device operates
in accordance with local regulatory guidelines, specifically for compliance with potential channel restrictions.
The antennas are only to be attached or swapped out while the device is powered off. Mounting or demounting antennas
while the device is powered on may cause the destruction of the radio module.
Gigabit Ethernet 10/100/1000
Only for devices with integrated DSL modem: If available and required, connect the G.FAST / VDSL / ADSL interfaces to a
TAE socket of your provider using suitable cables.
Mounting, installation, and commissioning of the device may only be carried out by qualified personnel.
Channel restrictions in Wi-Fi operation for devices with Wi-Fi interfaces
Use suitable cables or modules to connect other required device interfaces to other components and, in the case of
devices with mobile radio and/or Wi-Fi interfaces, connect any antennas supplied.
When operating this radio equipment in EU countries the frequency range 5,150 – 5,350 MHz (Wi-Fi channels 36 – 64) as
well as the frequency range 5,945 – 6,425 MHz (Wi-Fi channels 1 – 93) is limited to indoor use.

The mains plug of the device must be freely accessible.
a) Configuration in a network without active DHCP server b) Configuration in a network with active DHCP server
Operate the device only with a professionally installed power supply at a nearby and at all times freely accessible socket.
Only use the enclosed power supply / IEC cable or the one listed in the hardware quick reference.
For configuration via TCP/IP, the IP address of the device
in the local network (LAN) is required. After power-on, an
unconfigured LANCOM device first checks whether a DHCP
server is active in the LAN.
In this procedure, the DNS server used in your network must
be able to resolve the host name reported by the device via
DHCP. When using a LANCOM device as a DHCP and DNS
server, this is the default case.
A high touch current is possible for devices with metal housing and grounding screw! Before connecting the power supply,
connect the grounding screw to a suitable ground potential.
Simplified Declaration of Conformity
