Page 20: Introduction To The Client Adapters
Introduction to the Client Adapters Introduction to the Client Adapters The Cisco Aironet Wireless LAN Client Adapters are radio modules that provide transparent wireless data communications between fixed, portable, or mobile devices and other wireless devices or a wired network infrastructure. The client adapters are fully compatible when used in devices supporting Plug-and-Play (PnP) technology.
Page 21: Terminology
Radio Different radios are used for the 2.4-GHz and 5-GHz client adapters: The Cisco Aironet 340 and 350 series PC, LM, PCI, and mini PCI cards are IEEE 802.11b-compliant • client adapters. They contain a direct-sequence spread spectrum (DSSS) radio that operates in the 2.4-GHz Industrial Scientific Medical (ISM) license-free band.
Page 22: Radio Antenna
The client adapters have two LEDs that glow or blink to indicate the status of the adapter or to convey error messages. Refer to Chapter 9 for an interpretation of the LED codes. Note Mini PCI cards do not have LEDs. Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows OL-1394-04...
Page 23: Software Components
Client Utility The client utility, which is entitled Aironet Client Utility (ACU), is an optional application that interacts with the radio firmware to adjust client adapter settings and display information about the adapter. ACU is provided on the CD that shipped with the client adapter.
Page 24: Overview Of Acu
Figure 1-1 Aironet Client Utility Screen The status bar at the bottom of the Aironet Client Utility screen reflects the current state of your client adapter. Possible states include Associated, Not Associated, Not Inserted, Being Flashed with New Firmware, and Unable To Read Status from the Card.
