WLA620, WLA622 and WLA632 Overview
802.11an Radio
ANT-7360A-OUT (N-type female connector)
ANT-74520-OUT (3 RPSMA- male connector)
ANT-77555-OUT (3 RPSMA- male connector)
ANT-5007-OUT (2-N-type connector)
The port usage depends on the antennas in use. If the OMNI antennas are used there
must be 3 antennas installed for the radio. If the ANT-5007-OUT antenna is used then
the two edge ports must be connected to the antenna (ports 4 and 6). The middle port
will be turned off by the software and should be terminated. If either the ANT-77555 or
74520 are used all three connectors must be connected to the WLA for the correct
radio. (A RPSMA N-type adaptor is required.)

The antenna-location must be either indoors or outdoors. Although this is an outdoor
WLA it may be used indoors.

Multiple External Antenna Support
The WLA632 supports the use of multiple antenna ports per radio. Since there are
always multiple antennas connected, antenna diversity is always on. The command to
set the number of external antennas does not apply to the WLA632. The number of
antenna ports in use is determined by the antenna type.

If the ANT-5007-OUT antenna is in use on the 11a/n radio then the radio configuration
will revert to 2 x 3 mode rather than 3 x 3 mode and the middle port for the radio must
not be used.
Ethernet
The WLA632 supports a single IEEE 802.3-compliant auto-sensing 10/100/1000 BaseT
Ethernet interface on the Ethernet input connector. The WLA is configured as auto
MDI/MDIX. The WLA632 is powered from the WLA-XPS9001GO power supplies.
Informational Note:
Splitting the antennas between indoors and outdoors on the same
radio band is not allowed.
Caution:
The WLA622 and WLA632 must only be used with a Juniper
Networks-approved WLA-XPS9001GO outdoor power supply in order to prevent possible
damage to the unit.
Caution:
The 10/100 data port on the XPS is not used.
