Installing and Connecting an Access Point
Grounding
WLA620, WLA622, and WLA632
It is important that the WLA620, WLA622 and WLA632 units, cables, lightning
arrestors, and any supporting structures are properly grounded. The WLA620 and
WLA622 units include a grounding screw for attaching a ground wire. Be sure that
grounding is available and that it meets local and national electrical codes. The
WLA632 includes two grounding screws and a tubular lug for attaching a crimped
ground wire.
WLA Radio Safety Advisories
When you enable the WLA radio(s) as part of WLC configuration, the radios are able to
receive and transmit radio frequency energy as soon as you connect the WLA to the
WLC, either directly or through the network.
Radio Frequency Exposure
Federal Communications Commission (FCC) Docket 96-8 for Spread Spectrum
Transmitters specifies a safety standard for human exposure to radio frequency
electromagnetic energy emitted by FCC-certified equipment. When used with the
proper antennas (shipped in the product), Juniper Networks MP access point products
meet the uncontrolled environmental limits found in OET-65 and ANSI C95.1-1991.
Proper installation of the MP access point according to the instructions in this manual
will result in user exposure that is below the FCC recommended limits.

Installing a WLA620
The WLA620 includes a bracket kit for mounting the unit to a 3.81 to 5.08 cm (1.5 to 2
inch) diameter steel pole or tube. The pole-mounting bracket allows the unit to be
mounted to part of a radio mast or tower structure. The unit also has a wall-mounting
bracket kit that enables it to be installed on a building wall or roof when using external
antennas.
Hardware installation of the WLA620 involves these steps:
1.
Connect the Ethernet cable and a grounding wire to the unit.
2.
Mount the unit on a wall, pole, mast, or tower using the mounting bracket.
3.
Mount external antennas on the same supporting structure as the WLA620 and
connect them to the unit.
4.
Connect the power injector to the Ethernet cable, a local LAN switch, and an AC
power source.
5.
For wireless bridge or Mesh Services installations, align antennas at the bridge or
mesh link endpoints.
Caution:
Always ground the unit first with an appropriate grounding wire (not included)
by attaching it to the grounding screw on the unit.
