Earth connection (if necessary)—attach the earth cable to the earth screw
¾
of the LANCOM OAP Wireless and to a suitable earthed conductor.
When mounting the LANCOM OAP Wireless on poles or walls it may
be necessary to earth the housing to avoid dangerous differences in
potential. For grounding the LANCOM OAP Wireless please observe
the information on lightning protection in the LANCOM WLAN Out-
door Manual (available as a download from www.lancom.eu)
Antennas—screw the two supplied diversity antennas onto the two N
connectors on the top of the LANCOM OAP Wireless. An additional
antenna for the second WLAN module can be connected to the reverse N
connector on the underside of the device.
Antennas are only to be attached or changed when the device is
switched off. Mounting or demounting antennas while the device
switched on may cause the destruction of the WLAN module!
Antennas for LANCOM OAP-54 Wireless—screw the two supplied diver-
sity antennas onto the two N connectors on the top of the LANCOM OAP
Wireless. An additional antenna for the second WLAN module can be con-
nected to the reverse N connector on the underside of the device.
Antennas for LANCOM OAP-310agn Wireless—screw the supplied anten-
nas onto the N connectors on the top and bottom of the LANCOM OAP
Wireless. Depending on how the antennas are to be used, the 'Antenna
Grouping' parameter may need to be configured in order provide the
desired MIMO behavior
To attach an external antenna to a reverse N connector, use one of the
supplied "reverse N" to "N" adapter cables.
When assembling separately purchased mobile radio antennas please
note that the maximum allowed transmission power of the wireless
LAN according to EIRP in the country in question may not be
exceeded. The system operator is responsible for adhering to the
threshold values.
