Using the AP Array
The deployment of wireless local area network (WLAN) in a small office environment is often hindered by the lack of simplicity, stability
and affordability. Multiple access points (APs) will require more effort in configuration and management, and the complexity of security
settings adds to the burden. With limited resources in a small office, solutions provided for bigger organizations will be too complicated
and not economical.
D-Link’s AP Array is an ideal WLAN management tool for the small office. The WLAN management feature is built within the firmware,
making configuration for multiple APs an effortless process. All AirPremier 11n Business APs support this tool, which can manage up to
eight stand-alone APs. This will make WLAN deployment easier and more affordable.
Simple WLAN Management Tool
When one needs to set up a wireless local area network (WLAN) in a small office with limited IT resources, D-Link’s AP Array is the answer.
It allows the efficient deployment of a secured WLAN and easier administration from a single point; thus, minimizing the effort to maintain
the wireless network.

Easy Deployment and Management
With D-Link’s AP Array, deployment and management of APs are made simple. The following steps show how straightforward it is to deploy
the array of APs:
Step 1 - Deployment of Master AP:
•
Designate one AP as Master
•
Set up Array ID & password
•
Configure the AP
Step 2 - Deployment of Slave APs:
•
Specify Array ID & password of Master in Slave APs.
Step 3 - Settings Are Synchronized:
•
Backup Master & all Slave APs will follow configuration from Master automatically.
Up to eight stand-alone APs can be managed in an array. Members in the same AP Array group must be on the same subnet of the same
model, and each AP is assigned with a unique IP address.

Situations Encountered with the Different Implementations:
•
Multiple Master APs
: If there are two or more Master APs assigned in an array, the AP with the longest run-time will become the
Master AP.
Note:
The other Master APs will become Backup Master APs
.
•
Manually Configured Slave AP
: At intervals of one minute, the Master AP will send out a beacon to check the status of the Slave APs.
If any changes are done to the slave APs manually, the Master AP will automatically synchronize its configuration to the slave AP and
overwrite it.
•
Master AP Crashed
: In a situation where the Master AP becomes unavailable to the array, the Backup Master AP will take over the
Master role and synchronize the configuration to the Slave APs.
•
No Backup Master AP Available
: If the Master AP crashes and there are only Slave APs in the array, the Slave APs will work as
stand-alone APs until a new Master joins the array. The administrator may want to configure two Master APs for the array, so that there
is always a Backup Master AP available.

Section ³ - Using the AP Array
Whenever the user makes any changes in the Master AP and selects “Save & Activate”, the Master AP in an array will automatically
synchronize its configuration to all Slave APs.
Settings that can be synchronized are:
•
Wireless Settings
•
Multiple SSID & VLAN
•
WiFi Schedule
•
MAC Filter
•
WLAN Partition
•
DHCP Server
•
Log Settings
•
Time & Date
•
QoS Settings
•
Performance Settings
•
All Administrator Settings
Settings that are not synchronized are:
•
Operation Mode
•
Radio Channel
•
LAN Settings
If required, settings that are not synchronized will have to be configured individually for each AP.

Different AP Roles in an Array
There are three modes for the administrator to define the role of each AP.
•
Master AP
The Master AP can do all the management settings for members in an array. Each array can only have one Master AP.
•
Backup Master AP
In an event when the Master AP crashes, the Backup Master AP will take over the Master AP function. Each array can have up to two
Backup Master APs.
•
Slave AP
The Slave AP follows all the settings in the Master AP.
Easy Configuration of D-Link AP Array
The following section shows how simple it is to configure the D-Link AP Array for the different AP roles:
Master AP Role
