*1802020041011*
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.
The WAC-2004A has a default IP address of 192.168.127.253, which you must use when connecting to the device via LAN 1 (LAN 2 is reserved for future expansion) for the first time. When configuring the WAC-2004A for the first time, use the following default username and password:
Username: admin
Password: moxa
ATTENTION
For security reasons, we strongly recommend changing the default password. To do so, select Maintenance Username/Password, and then follow the on-screen instructions.
To make the changes effective, you must click Save Configuration to save the changes (Restart to apply the changes).

Mounting Dimensions
Rackmount
Use six screws to attach the WAC-2004A to a standard rack.
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 used 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 disconnected, 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.
| Pin | 10/100 Mbps | 1000 Mbps |
| 1 | ETx+ | TRD(0)+ |
| 2 | ETx- | TRD(0)- |
| 3 | ERx+ | TRD(1)+ |
| 4 | – | TRD(2)+ |
| 5 | – | TRD(2)- |
| 6 | ERx- | TRD(1)- |
| 7 | – | TRD(3)+ |
| 8 | – | TRD(3)- |
NOTE The pin numbers for the 8-pin RJ45 connectors (and ports) are typically not labeled on the connector (or port). Refer to the diagram above to see how the RJ45’s pins are numbered.
Serial Console Connection
The WAC-2004A provides one serial port with a DB9 male connector for its console access. The pin assignments are shown in the following table:
| Pin | RS–232 |
| 1 | DCD |
| 2 | RxD |
| 3 | TxD |
| 4 | DTR |
| 5 | GND |
| 6 | DSR |
| 7 | RTS |
| 8 | CTS |
| 9 | – |
NOTE The pin numbers for the male DB9 connectors, and hole numbers for the female DB9 connectors are labeled on the connector. However, the numbers are typically very small, so you may need to use a magnifying glass to see the numbers clearly.
