ZyAIR B-420 Wireless LAN Ethernet Adapter and Bridge

1 Introducing the ZyAIR

The ZyAIR B-420 is an IEEE 802.11b compliant wireless LAN Ethernet Adapter and Bridge. The driven­free installation process makes setup easy. You can also configure your ZyAIR through the user-friendly
web configurator or SMT menus. The key features of the ZyAIR are PoE (Power over Ethernet) and the
ability to function in bridge mode. See your User’s Guide for more details on all ZyAIR features.

LABEL DESCRIPTION

ETHERNET For initial configuration use an Ethernet cable to connect a computer (with an Ethernet

card) to this port. The port is auto-negotiating (can connect at 10 or 100Mbps) and auto­crossover (automatically adjusts to the type of Ethernet cable you use (straight-through
or crossover)).

RESET You only need to use this button if you’ve forgotten the ZyAIR’s password. It returns the

ZyAIR to the factory defaults (password is 1234 and LAN IP address 192.168.1.11).
Refer to the User’s Guide.

POWER
12VDC

Connect the end of the included power adaptor to this power socket. You only need to
connect the external power adaptor if you are not using PoE. If you simultaneously use
both PoE and the external power adaptor, the ZyAIR will draw power from the PoE
connection only.

Use only the included power adaptor.
