20 CHAPTER 2: INSTALLING THE ETHERNET ADAPTER
Attaching An External Antenna
The Ethernet Adapter has two internal diversity dual-band antennas.
If you want to increase the range of the Ethernet Adapter, an external
antenna can be attached to the external antenna connector on the
Ethernet Adapter.
The Enterasys Networks-approved external antenna for this Ethernet
Adapter is the Enterasys Networks 2.4/5 GHz Omnidirectional Workgroup
Ethernet Adapter Antenna. For more information, go to

Determining if you Need to Configure the Ethernet Adapter
If your network has a DHCP server and no special security requirements,
you can most likely use the Ethernet Adapter just as it is shipped from the
factory.
It takes approximately one to two minutes for the Ethernet Adapter to
determine if there is a DHCP server on the network.
View the Ethernet Adapter’s default settings on page22 to determine
whether or not you need to configure the Ethernet Adapter for your
network. If the factory defaults meet your requirements, you can connect
the Ethernet Adapter as described in “Connecting the Ethernet Adapter”
on page 15.
If your network does not have a DHCP server or is more complex, you
may have to configure the Ethernet Adapter and organize devices so that
you can manage the wireless LAN easily and keep it secure. You can use
the Enterasys Networks Wireless Infrastructure Device Manager (Widman)
included on the Enterasys Networks Installation CD.
For non-U.S. versions of the Ethernet Adapter, you need to set the Country
mode. This is done when you first open the Ethernet Adapter’s Configuration
Management System. See “Using the Configuration Management System” on
page29 for instructions.
Networks with a DHCP Server
If your network has a DHCP server, an IP address is automatically assigned
to the Ethernet Adapter. It takes approximately one to two minutes for the
Ethernet Adapter to determine if there is a DHCP server on the network.
