Introduction
The D-Link DSA-5100 Airspot Enterprise Gateway is an advanced network access
control system supporting Ethernet, Fast Ethernet or an IEEE 802.11 wireless LAN
(WLAN) separately and simultaneously.
TheDSA-5100canbeconfigured withastandardHTMLbrowser(i.e.,Internet Explorer,
or Netscape Navigator) operating on Windows 98SE/Me/2000/XP, Macintosh OS 9,
Macintosh OS X (v10.1.5 or later), Linux, or Pocket PC 2000/2002. The DSA-5100
allows the operator to offer wired or wireless networking services and access to the
Internet when used with a switch or wireless access point respectively. The device
features many management settings allowing for private and public access to the
Internet and the necessary privilege mechanisms to permit this usage.

Installation Requirements
1. Standard 10/100Base-T, including four network cables with RJ-45
connectors.
2. All PCs need to install the TCP/IP network protocol.
1. Make sure the power of the DSA-5100 is turned off.
2. Connecting the WAN1 and WAN2 ports.
Useoneof thesuppliedstraight-through cablestoconnect theDSA-5100tothenetwork
notmanagedbythe DSA-5100system(suchas andATU router forADSL, theEthernet
port of a cable modem, or a switch or hub on a LAN).
3. Connecting the Public LAN port.
ThePublicLANportis usedtoprovideauthenticationbased Internetaccessfor Ethernet
(with switch) or WLAN (with AP) clients. Use one of the supplied straight-through
Ethernet cables if connecting to a hub or switch. Use the supplied crossover cable if
connecting directly to an AP or PC.
Warning: The Public LAN port cannot connect to a Layer 3 device.
4. Connecting the Private LAN port.
The Private LAN port is used to provide Internet access without authentication for
yourexistingPrivateNetwork. Useoneofthe suppliedstraight-throughEthernetcables
ifconnectingtoahub or switch. Use thesuppliedcrossovercableifconnecting directly
to an AP or PC.
Setting Up the DSA-5100
5. Turn on the power.
Plug the bundled power cord connector into the socket and then turn on the power.
6. Check the LED indicating light.
After the power is ON, the power LED should be lit. The WAN1, WAN2, Public LAN,
and Private LAN LEDs will light up with a valid Ethernet connection.

Setting Up the DSA-5100 (continued)
TCP/IP Network Setup
For Windows 98SE/ME/2000/XP, you need to keep the default TCP/IP settings
(“obtainIP andDNSaddressautomatically”) to communicate with theDSA-5100.
The DSA-5100 leases DHCP addresses from the Public and Private LAN ports
for ease of configuration.
For Non-Server Windows operating systems, the default setting for TCP/IP is
“DHCP client,” which will obtain an IP address automatically.
If you wish to use a static IP on the public or private LAN section, or you wish to
check the TCP/IPsetup, please refer to theAppendix – WindowsTCP / IPSetup.
