About this Guide
Dell PowerConnect W-Series Instant Access Point is a simple, easy to deploy turn-key WLAN solution consisting
of one or more access points. An Ethernet port with routable connectivity to the Internet or a self-enclosed
network as long as there is an Ethernet port with link are the network infrastructures required to deploy the Dell
PowerConnect W-Series Instant wireless network. Dell PowerConnect W-Series Instant is specifically designed
for easy deployment and proactive management of networks for small customers or remote locations without an
on-site IT administrator.
Dell PowerConnect W-Series Instant consists of at least one Instant Access Point (IAP) and a Virtual Controller
(VC). The virtual controller resides within one of the access points. In Dell PowerConnect W-Series Instant
deployment only the first IAP needs to be configured. After the first IAP is deployed, the subsequent IAPs will
inherit all required information from the virtual controller. Dell PowerConnect W-Series Instant network can
support upto 16 IAPs and 256 users.
Objective
This user guide describes the various features supported by Dell PowerConnect W-Series Instant and provides
detailed instructions for setting up and configuring a Dell Instant network.
Intended Audience
This guide is intended for Dell PowerConnect W-Series Instant customers who will be configuring and using Dell
Instant to set up the Dell Instant wireless network infrastructure.

W-IAP Internal Antenna Patterns
This chapter provides information about the internal antenna patterns in W-IAP92, W-IAP93, and W-IAP105.
W-IAP92 and W-IAP93 Antenna Patterns
The antenna specifications of W-IAP92 and W-IAP93 are as follows:
W-IAP92: Dual, RP-SMA interfaces for external antenna support (supporting up to 2x2 MIMO with spatial
diversity). For information to configure an external antenna, see “Configuring an External Antenna” on
page63.
W-IAP93: Integrated, omnidirectional antenna elements (supporting up to 2x2 MIMO with spatial diversity)
Maximum antenna gain for W-IAP92 and W-IAP93:
2.4 GHz/2.5 dBi
5 GHz/5.8 dBi
Figure 1 shows antenna patterns of W-IAP93 for 2.45 GHz and 5.5 GHz.
Figure 1 W-IAP93 Antenna Pattern
Dell PowerConnect W-Instant Access Point 5.0.3.0-1.1.0.0 | User Guide W-IAP Internal Antenna Patterns | 15
W-IAP105 Antenna Pattern
The antenna specifications of W-IAP105 are as follows:
4 x integrated, omnidirectional antenna elements (supporting up to 2x2 MIMO with spatial diversity)
Maximum antenna gain:
2.4 GHz/2.5 dBi
5.150 GHz to 5.875 GHz/4.0 dBi
Figure 2 shows antenna patterns of W-IAP105 for 2.45 GHz and 5.5 GHz.

Initial Configuration
This chapter provides information that is required to setup Instant and access the Instant User Interface.
Initial Setup
This section provides a pre-installation checklist and describes the initial procedures required to set up Dell
Instant.
Pre-Installation Checklist
Before installing the Instant Access Point (IAP), make sure that you have the following:
Ethernet cable of required length to connect the IAP to the home router.
One of the following power sources:
IEEE 802.3af-compliant Power over Ethernet (PoE) source. The PoE source can be any power source
equipment (PSE) switch or a midspan PSE device.
Dell power adapter kit (this kit is sold separately).
NOTE: PoE is a method of delivering power on the same physical Ethernet wire that is used for data communication. Power for
devices is provided in one of two ways:
Endspan: The switch that the AP is connected to can provide power.
Midspan: A device can sit between the switch and the AP.
The choice of endspan or midspan depends on the capabilities of the switch that the AP will be connected to. Typically if a switch
is in place and does not support PoE, midspan power injectors are used.
NOTE: A DNS server functions as a phonebook for the Internet and Internet users. It converts human readable computer
hostnames into IP addresses and vice-versa. A DNS server stores several records for a domain name, such as address 'A' record,
name server (NS), and mail exchanger (MX) records. Address 'A' record is the most important record that is stored in a DNS server
because it provides the required IP address for a network peripheral or element.
NOTE: The Dynamic Host Configuration Protocol (DHCP) is an auto-configuration protocol used on IP networks. Computers or any
network peripherals that are connected to IP networks must be configured before they can communicate with other computers on
the network. DHCP allows a computer to be configured automatically, thereby eliminating the need for a network administrator.
DHCP also provides a central database to keep a track of computers connected to the network. This database helps in preventing
any two computers from being configured with the same IP address.
To complete the initial setup, perform the following tasks in the given order:
1. “Connecting the W-IAP to a Power Source” on page18
2. “Assigning an IP Address to the W-IAP” on page18

5. “Specifying the Country Code” on page20 Skip this step, if you are installing the W-IAP in United States,
Japan or Israel.
Connecting the W-IAP to a Power Source
Based on the type of the power source that is used, perform one of the following steps to connect the W-IAP to
the power source:
PoE switch - Connect the ENET port of the W-IAP to the appropriate port on the PoE switch.
PoE midspan - Connect the ENET port of W-IAP to the appropriate port on the PoE midspan.
AC to DC power adapter - Connect the 12V DC power jack socket to the AC to DC power adapter.
Assigning an IP Address to the W-IAP
The W-IAP needs an IP address for network connectivity. When you connect the W-IAP to a network, the WIAP receives an IP address from a DHCP server. To get an IP address for an W-IAP, perform the following steps:
1. Connect the ENET port of W-IAP to a switch or router using an Ethernet cable. Ensure that the DHCP
service is enabled on the network.
2. Connect the W-IAP to a power source. The W-IAP will receive an IP address provided by the switch or router.
NOTE: After the IAP starts up, it will try to do DHCP if static IP configuration is not available. If DHCP times out, a default IP within
169.254.x.y/16 subnet will be configured on the IAP. The DHCP client will be still running so that when the DHCP service recovers
the IAP will get a valid IP address and then reboots.
Connecting to the Provisioning Wi-Fi network
Connect a wireless enabled client to the provisioning Wi-Fi network. The provisioning network name is instant.
In the Microsoft Windows operating system, click the wireless network connection icon in the system tray.
The Wireless Network Connection box appears. Click on the instant network and click Connect.
In the MAC operating system, click the AirPort icon. A list of available Wi-Fi networks is displayed. Click on
the instant network.
NOTE: While connecting to the provisioning Wi-Fi network, ensure that the client is not connected to any wired network.
