Hardware Description
The SMC2890W-AN/SMC2891W-AN outdoor access point (AP) is built with leading-
edge technology to deliver reliable high-performance connectivity for your data
network.
The SMC2890W-AN/SMC2891W-AN is a dual-band IEEE 802.a/b/g/n AP that is
designed to deliver high-performance wireless services for clients or to provide
bridge links between remote LANs. Housed in a weatherproof enclosure for
mounting outdoors, the unit includes its own bracket for attaching to a pole, radio
mast, or tower structure. The unit is powered through its Ethernet cable connection
from a power injector module that is installed indoors.
In addition, the AP offers full network management capabilities through an easy-
to-use web interface, a command-line interface, and support for Simple Network
Management Protocol (SNMP) tools.
