A Juniper Networks model WLA620 provides IEEE 802.11 wireless access to the network.
WLAs are designed for use with a Juniper Networks WLAN controller. WLAs require
hardware installation only. All configuration for an WLA is performed on the WLC.
Warning: Installation must be performed by qualified service personnel only. Read and
follow all warning notices and instructions marked on the product or included in the
documentation. Before installing the product, read the Regulatory Guide document.
Informational Note: The WLA radios are disabled by default and can be enabled only by
a system administrator using the WLC.
Hardware Overview
WLA620
The WLA620 provides wireless access point services for clients in the local LAN ar ea,
and can provide point-to-point or point-to-multipoint wireless bridge links between
remote Ethernet LANs. The WLA is housed in a weatherproof enclosur e for mo untin g
outdoors and includes brackets for attaching to a wall, pole, radio mast, or tower
structure. The unit is powered through an Ethernet cable connection from a power
injector module installed indoors. The WLA620 provides a 54 Mbps half-duplex
connection for each active channel.
A wireless bridge system offers a solution for connectivity between remote Ethernet
wired LANs, or to provide Internet access to an isolated site where a wired link may be
difficult or expensive to deploy. The wireless bridge connection provides data rates of
up to 108 Mbps.
Radio Characteristics – The IEEE 802.11a and 802.11g standards use a radio
modulation technique known as Orthogonal Frequency Division Multiplexing (OFDM),
and a shared collision domain (CSMA/CA). The 802.11a standard operates in the 5
GHz Unlicensed National Information Inf ra str uc tu re (UNII ) ba nd , an d th e 80 2. 11g
standard in the 2.4 GHz band.
IEEE 802.11g includes backward compatibility with the IEEE 802.11b standard. IEEE
802.11b also operates at 2.4 GHz, but uses Direct Sequence Spread Spectrum
(DSSS) and Complementary Code Keying (CCK) modulation technology to achieve a
communication rate of up to 11 Mbps.
The WLA622 provides only external antenna options and is designed to operate as the
“root bridge” in point-to-multipoint configurations, supporting wireless bridge
connections to as many as six units. The WLA is housed in a weatherproof enclosure
for mounting outdoors and includes brackets for att aching to a wall, pole, radi o mast, or
tower structure. The wireless bridge connection provides data rates of up to 54 Mbps. A
WLC cannot be used to power the outdoor WLA. The WLA requires a Juniper-designed
XPS power supply for proper operation.
WLA632
The WLA632 is a 802.11a/b/g/n WLA that is designed for pole-mounting and wall
mounting. The WLA632 supports 6 antenna ports, 3 for the 11a/n radio and 3 for the
11b/g/ n ra dio . A nt en na s ot he r than Juniper approved antennas are not supported. The
WLA632 does not support internal antennas or PoE. A WLC cannot be used to power
this WLA. A WLA-XPS9001GO power supply that uses the IP67 multi-pin DIN
connector is required. The WLA-XPS9001GO is specifically designed for the WLA632
and is available from Juniper Networks.
WLA-XPS9001GO Power Supply Unit
The WLA-XPS9001GO PSU has separate SKUs for North American and International
users.
WLA-XPS9001GO-NA— An outdoor 802.3at compliant, 100-240 VAC 50-60Hz input,

External antennas connect to the N-type RF connectors on the WLA620 using the
provided coaxial cables.
Ethernet Port
The WLA620 has one 10BASE-T/100BASE-TX 8-pin DIN port that connects to the
power injector module using the included Ethernet cable. The Ethernet port connection
provides power to the WLA620 as well as a data link to the local network.
Informational Note: The power injector module does not support Power over Ethernet
(PoE) based on the IEEE 802.3af standard. The WLA620 must always be powered on by
being connected to the power injector module.
Power Injector Module
The WLA620 receives power through the network cable connection using
power-over-Ethernet technology. A power injector module is included in the WLA620
package and provides two RJ45 Ethernet ports, one for connec tin g to th e WLA620
(Output), and the other for connecting to a WLC switch or a local LAN switch (Input).
The Input port uses an MDI (i.e., internal straight-through) pin configuration. You can
therefore use straight-through twisted-pair cable to connect this port to most network
interconnection devices such as a switch or router that provide MDI-X ports. However,
when connecting the access point to a workstation or other device without MDI-X ports,
you must use crossover twisted-pair cable.
Figure 1–3. Power Injector Module
The WLA620 does not have a power switch. It is powered on when the Ethernet port is
connected to the power injector module, and the power injector module is connected to
an AC power source. The power injector includes one LED indicator tha t turns on when
AC power is applied.
The power injector module automatically adjusts to any AC voltage between 100-240
volts at 50 or 60 Hz. No voltage range settings are required.
Warning: The power injector module is designed for indoor use only. Never mount the
power injector outside with WLA620 unit.
Receive Signal Strength Indicator (RSSI) BNC Connector
The RSSI connector provides an output voltage that is proportio nal to the received radio
signal strength. A DC voltmeter can be connected the this port to assist in aligning the
antennas at both ends of a wireless bridge link.
Grounding Point
Even though the WLA620 includes a built-in lightning protection, it is important that the
unit is properly connected to ground. A grounding screw is provided for attaching a
ground wire to the unit.
Wall- and Pole-Mounting Bracket Kits
The WLA620 includes bracket kits that can be used to mount the unit to a wall, pole,
radio mast, or part of a tower structure.
If you are using the WLA620 with an outdoor antenna, Juniper Networks recommends
installing an external lightning protector for the antenna. An external lightning protector
may be obtained from Juniper Networks.

WLA620, WLA622 and WLA632 Overview
External Antenna Options
The WLA622 supports one or two antennas per radio. If there are two antennas
connected to the radio then antenna diversity is used to send all traffic types. If there is
one antenna then proper operations of antenna diversity may be affected.
By default there is one external antenna so there will be no use of antenna diversity for
WLAs with external antennas defined. The setting below is applied per radio so you can
have one radio indoors and one radio outdoors.
set ap num radio num external-antennas num
Informational Note: This is a new command, and it is only supported in MSS 7.1 or higher.
Caution: The splitting of antennas on a single radio between indoors and outdoors is not
allowed.
The WLA622 supports one or two antennas per radio. If there are two antennas they
must be the same antenna model. A single antenna will always be connected to the
connector 1 for 2.4 GHz and connector 3 for 5Ghz.
The WLA622 supports four antenna ports, two for the 11a radio and two for the 11bg
radio. The supported antennas models are:
802.11bg Radio
ANT-1120-OUT
ANT-1360-OUT
802.11a Radio
ANT-5120-OUT
ANT-5360-OUT
ANT-5PNL-OUT (for single antenna only for use on port 3)
External antennas connect to the N-type RF connectors on the wireless bridg e either
directly or using coaxial cables.
Ethernet Port
The wireless bridge has one 10BASE-T/100BASE-TX 8-pin DIN port that connects to
the power injector module using the included Ethernet cable. The Ethernet port
connection provides power to the wireless bridge as well as a data link to the local
network.
The wireless bridge appears as an Ethernet node and performs a bridging function by
moving packets from the wired LAN to the remote end of the wireless bridge link.
Informational Note: The power injector module does not support Power over Ethernet
(PoE) based on the IEEE 802.3af standard. The wireless bridge unit must always be
powered on by being connected to the power injector module.
Power Injector Module
The WLA622 receives power through the network cable connection using
Power-over-Ethernet (PoE) technology. An outdoor power injector module is available
seperately and provides two RJ45 Etherne t ports, one for conn ecting to the WLA622
(PoE Output), and the other for connecting to an WLC or a local LAN switch Data
(Input).
The Input port uses an MDI (i.e., internal straight-through) pin configuration. You can
therefore use straight-through twisted-pair cable to connect this port to most network
interconnection devices such as a switch or router that provide MDI-X ports. However,
when connecting the access point to a workstation or other device without MDI-X ports,
you must use crossover twisted-pair cable.
The WLA622 does not have a power switch. It is powered on when the Ethernet port is
connected to the power injector module, and the power injector module is connected to
an AC power source.
The power injector module automatically adjusts to any AC voltage between 100-240
volts at 50 or 60 Hz. No voltage range settings are required.
Caution: The power injector module is designed for indoor use.
Grounding Point
In order for the WLA622 includes a built-in lightning protector to work properly, the unit
must be properly connected to ground. A grounding screw is provided for attaching a
ground wire to the unit.
Water Tight Test Point
Caution: Do not remove or loosen this screw. If you do, you can damage the unit.
Wall- and Pole-Mounting Bracket Kits
The WLA622 includes bracket kits that can be used to mount the unit to a wall, pole,
radio mast, or part of a tower structure.
Lightning Protector for Outdoor Antenna
If you are using the WLA622 with an outdoor antenna, Juniper Networks strongly
recommends installing an external lightning protector for the antenna. An external
lightning protector may be obtained from Juniper Networks.
System Configuration
At each location where an WLA622 unit is installed, it must be connected to the local
network using the power injector module. The following figure illustrates the system
component connections.
The WLA622 provides the following features and benefits:
The WLA622 supports access point services for the 5 GHz and 2.4 GHz radios using
various external antenna options
WLA622 units support 5 GHz point-to-multipoint links using various external
Juniper-supplied antenna options

Scans all available channels and selects the b est channel and data rate based on the
signal-to-noise ratio.
Manageable through an easy-to-use web-browser interface, command line (via Telnet),
or SNMP network management tool.
Informational Note: Two separate cables are required for power and ethernet function
on the WLA632. Both the cable dongles are RJ45 on one end, but one cable is specific to
power and one is specific to data. If the RJ45 cable ends are swapped, the unit will not
power up but will not be damaged. If the RJ45 cable ends are correctly inserted, the unit
will function normally.
LED Indicators
The WLA632 has LEDs that provide status information for the device. The table below
lists the function of the LEDs.

Radio is unable to transmit. This state can occur due to any of the following:
Excessive radio interference in the environment is preventing the radio
from sending beacons.
DFS has detected radar and is restricting traffic.
The radio has failed.
Radio is disabled and active scan is enabled. (The radio is in sentry
mode.)
Radio is enabled, but no clients are associated with it.
External Antenna Options
The WLA632 supports six antenna ports, 3 for the 11a/n radio and 3 for the 11b/g/n
radio. The 3 802.11 b/g/n antenna ports are on the top of the WL A an d a re nu mbe re d 1
to 3 from left to right. The 3 802.11a/b/g/n antenna ports are on the bottom of the WLA
with the ethernet and power ports. The antenna ports are numbered 4 to 6 from left to
right with port 4 on the outside edge of the RJ45 ethernet port.
The supported antennas models are:
802.11bgn Radio
ANT-7360A-OUT (N-type female connector)
ANT-77555-OUT (3 RPSMA- male connector)
ANT-74520-OUT (3 RPSMA- male 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.)
set ap apnum radio num antennatype {ANT-7360A-OUT | ANT 77555-OUT | ANT
74520-OUT | ANT-5007-OUT} …
The antenna-location must be either indoors or outdoors. Although this is an outdoor
WLA it may be used indoors.
set ap apnum radio # antenna-location {indoors | outdoors}
Informational Note: Splitting the antennas between indoors and outdoors on the same
radio band is not allowed.
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.
set ap num radio num external-antennas num
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.
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.
Caution: If you convert the 8 pin female circular DIN data port on the WLA632 bulkhead
to a standard RJ45 waterproof connection for the 10/100/1000 data port, PoE on the
10/100/1000 port must be disabled to prevent service interruption.The WLA632 does not
support PoE on the 10/100/1000 Ethernet data port.
Caution: Always add the waterproof cap to the RJ45 cable when installing the DIN-RJ45
dongle. Water can cause damage to the unit and the cables.
The WLA632 48VDC / Ethernet inputs provides primary and secondary lightning
protection up to 4KV on all conductors.
The Ethernet interface supports a cable length of up to 100m over CAT5e or CAT6
cable.
Grounding Point
Caution: Always ground the unit first with an appropriate grounding wire (not included)
by attaching it to the grounding screw on the unit.
The WLA632 has a two-hole grounding boss with threaded screws and washers for
direct electrical connection to earth ground. The two-hole tubular lug can be crimped
(standard crimp tool is required) on a AWG #8 copper wire for grounding.
Water Tight Test Point
Caution: Do not remove or loosen the pressure balance plug on the side of the unit. If you
do, you can damage the unit.
Wall- and Pole-Mounting Bracket Kits
The WLA632 includes bracket kits that can be used to mount the unit to a wall, pole,
radio mast, or part of a tower structure.
Lightning Protector for Outdoor Antenna
If you are using the WLA632 with an outdoor antenna, Juniper Networks strongly
recommends installing an external lightning protector for the antenna. An external
lightning protector may be obtained from Juniper Networks.
