7 Supported OS Windows Operating Systems The Aironet Windows driver disk includes drivers for: Windows 95 and 98 and Windows ME, Windows NT, Windows 2000, Windows XP Windows CE 2.x, 3.x, and 4.x Linux and Macintosh Linux using kernel versions 2.2.x or 2.4.x with Macintosh PowerBooks and PowerMacs using Mac OS 9.x or Mac OS X 10.1 not for use with Macintosh notebooks that have a built-in wireless card (AirPort) Cisco Connection Online (CCO)

8 1200 Series Access Point Ports
Ethernet Port with or w/o power DC Power Console Port The 1200 Access Point has the following ports on the top port panel: Link Light: Lights solid green to indicate that 10BaseT/100BaseT has been configured as the active port. Traffic: Flashes green when an Ethernet packet has been received. Console Port: RJ-45 Console port. (rollover cable) The 1200 Access Point can be powered by it’s DC power port or by power over Ethernet using an optional power injection module, or using another powered Cisco device (patch panel, switch). To communicate with the access point via the console port, use a terminal emulation program (such as HyperTerminal) with the following settings: 9600 Baud 8 Data Bits No Parity 1 Stop Bit Flow Control Xon/Xoff Mode or Default config reinit button Link Traffic

10 Available power modes

11 Connecting to the Access Point
Console port Requires roll-over cable Telnet Requires an IP address Web Browser Preferred connection To set an IP address: Use DHCP Server Use IPSU Set using Console port Console Port Telnet Web Browser As designed, manage Cisco Aironet Access Point using a Web browser. Telnet and Console port menus are much more difficult to utilize. To set an IP address you can either use DHCP or the Cisco Aironet IP Setup utility (IPSU).

12 Force an IP via DHCP or IPSU
Make sure that the IPSU is installed on your laptop. You must also have a wireless adapter and an RF connection with the access point on which you want to change the IP address. The IPSU is available as a download from the Cisco website. Double-click the IPSU icon on your computer desktop to start IPSU. Make sure Set Parameters is selected in the Function box. In the Device MAC ID field, enter the MAC address as it appears on the label on the bottom of the access point. It should contain six pairs of hexadecimal digits separated by periods or dashes. In the IP Address field, enter the IP address you want to assign to the access point. The IP address should be on the same subnet as the device to which you will connect the access point. In the SSID field, enter the SSID you want to assign to the access point. You cannot set the SSID without also setting the IP address. However, you can set the IP address without setting the SSID. Click Set Parameters. IP address is set on the access point. This is best done through a Ethernet connection.

13 Consider the AP as a bridge
AP extends wired features to the wireless BVI : Bridge Virtual Interface From which you manage the AP FastEthernet0 is the first interface Dot11Radio0 is the second interface is simply another interface on AP The commands fit into the IOS architecture as just another interface. Taking features used in a wired environment and extending them to a wireless interface. In the example above you see the FastEthernet0 is the first interface and the Dot11Radio0 is the second interface.

23 Cisco Aironet 1100 Series Internal View
2.2 dBi Omni-Directional Diversity Antennas Mini-PCI Radio Option 1: b The chassis design of Cisco Aironet 1100 Series Access Point allows the end user to upgrade the Mini-PCI radio from b to g in the future. Simply remove one screw from the back of Cisco Aironet 1100 Series to access the Mini-PCI Radio. Then remove the b radio and replace it with a g radio. The procedure likens the same process as removing and installing computer memory modules. End users will not be able to upgrade Cisco Aironet 1100 Series antennas because it uses a captured antenna. A captured antenna is a antenna that is integrated into the access point to provide ease of installation and WLAN design. The 2.2 dBi omni-directional antenna is engineered to provide antenna diversity to help combat Multipath distortion. Cisco Aironet 1100 Series Access Points antennas provides comparable coverage performance as a pair of 2.2 dBi rubber duckie antennas. Items to note: Cisco Aironet 1100 Series Access Points only supports the b. In the future it will support g. Cisco Aironet 1100 Series Access Points will not support external antennas.

24 Cisco Aironet 1200 Access Point the 5 GHz Upgrade
5 GHz technology allows for the addition of an 11a network over your 11b network + 802.11a = 802.11b+a With simultaneous support for both 2.4 GHz and 5 GHz radios, the Cisco Aironet 1200 Series preserves existing IEEE b investments and provides a migration path to future IEEE a and IEEE g technologies. Its modular design supports single- and dual-band configuration, plus the field upgradability to change these configurations as requirements change and technologies evolve. Investment protection is further provided by large storage capacity and support for Cisco management tools, delivering the capacity and means to upgrade firmware and deliver new features as they become available. 802.11b

Front Cover LED’s Status Lights Ethernet Status Radio Activity Ethernet Activity Status Radio Activity The status light provides updates on the operation of the unit itself. The most important feature of the light is the ability to determine if there are any remote devices communicating with it. Blinking: No associations Solid: At least one association The status light will also flash amber any time the system notes that an error has occurred. This light would prompt you to look into the history logs to form a review of errors that have been reported. The radio and Ethernet LED indicate activity (TX or RX) over these mediums. Typically the Ethernet will blink much faster than the RF since there will be more traffic on the Ethernet side than the RF side. If the RF LED is blinking much more that the Ethernet, this is an indication there is a lot of radio traffic going on without corresponding Ethernet traffic. This could be from an RF test routine, or from poor communication causing RF retries. Any RED LED during normal operation indicates a problem, and typically indicates a firmware or hardware failure.
