Overview
The goal of zero-latency roaming is to allow clients to seamlessly
maintain their communications as they move from one access point to
another. The advanced Moxa Wireless Access Controller, the WAC-
2004A, together with controller-based Turbo Roaming technology,
enables millisecond-level roaming over different IP subnets. The
advanced roaming algorithm along with Mobile IP technology allow
wireless clients to roam between APs in different IP subnets within
milliseconds while upholding stringent security in demanding
environments. The WAC-2004A is rated to operate at temperatures of 0
to 50°C and is rugged enough for on-site installation in any harsh
industrial environment.

Installation and Configuration
Before installing the WAC-2004A, verify that all items in the Package
Checklist are in the box.
Note that the WAC-2004A must be configured before use. Refer to the
WAC-2004A Series User’s Manual for more details.

Grounding the WAC-2004A
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground wire from the
ground screw on the rear side (shown below) to the grounding surface
prior to connecting devices.
ATTENTION
If protective earthing is us
ed as a safeguard, the instructions
shall require connection of the equipment protective earthing
conductor to the installation protective earthing conductor (for
example, by means of a power cord connected to a
socket
outlet with earthing connection).
Connecting the Power Inputs
The WAC-2004A supports dual redundant power supplies: Power Supply
1 (PWR1) and Power Supply 2 (PWR2). The connections for PWR1 and
PWR2 are located on the rear side (shown below). Be sure to use a
standard power cord with an IEC C13 connector, which is compatible
with the AC power inlet.
NOTE
The WAC-2004A is powered up automatically once the AC
power cord is connected and the switch on the power connector
on
the back panel is set in the On position.
To power off the WAC
-2004A, press the Power button on the
front panel for 5 to 10 seconds. Turn off the switch
on the
power connector
and remove the power cord if necessary.
If the power connector switch is not turned off
, the AC power
is
not disconnecte
d, and the WAC-2004A was powered off using
the
Power button, the device can be powered back on by
pressing the Power button again.

ATTENTION
Please
make sure the switch on the PWR1 and PWR2
connectors
on the back of the WAC-2004A are turned off
before
connecting the power cords and physically installing the device.
Pin Assignments
Gigabit Ethernet Port Connection
The WAC-2004A provides 1 Gigabit Ethernet connector (LAN 1) and 1
reserved Ethernet connector (LAN 2) for future expansion. When the
cable is properly connected, the LEDs on the RJ45 connectors will glow
to indicate a proper connection.
