Cable and

Power


Cisco Aironet 1100 and 1200 Series, can be powered over Ethernet

with: Switch with inline power (Option 1)

Inline power patch panel (Option 2)

Optional inline power injector (Option3)

Universal power supply (Option 4)

WARNINGNever connect both the DC power to the APpower port and inline power simultaneously

LED indicators

1100 AP 1200 AP


The LED lights on an access point convey status information. When the access point is powering on, all three LEDs normally blink. After bootup, the colors of the LEDs represent the following:

Green LEDs indicate normal activity.

Amber LEDs indicate errors or warnings.

Red LEDs mean the unit is not operating correctly or is beingupgraded.

Reset the AP (Power On)

, ,

you will reset the AP. Follow these steps to reset the access point to factory default

settings using the access point MODE button:

Step 1 Disconnect power (the power jack for external power or theEthernet cable for in-line power) from the access point.

Step 2 Press and hold the MODE button while power to the accesspoint is reconnected.

Step 3 Hold the MODE button until the Status LED turns amber(approximately 1 to 2 seconds), and release the button. All access

point settings return to factory defaults.


11/72

Reset the AP (Power On)

350 AP


The Reset button on the 340 and 350 AP is in a small hole on the backpanel of the base station.

To activate the Reset button, insert a straightened paper clip into thesmall hole and press.

Remove the paper clip. The Status LED blinks amber to show the base station has the

default parameter values.

privilege password, not theWEP password.

Connecting to the AP (Wireless)

SSID = tsunamiSSID = tsunami


Wireless adapter: If configuring using the wireless adapter, you must first associate

with the AP.

Make sure the settings on the ACU match the AP. Cisco 1100 and 1200 Aps have the following defaults:

IP Address = 10.0.0.1 255.255.255.224

SSID = tsunami

Password = Cisco (C not c)

Connecting to the AP (Wired)

Wired Ethernet: No association necessary

Make sure the IP Address on the Ethernet interface is on the samesubnet as the AP.

APs during labs so we do not configure the wrong AP via wireless.

Labs and Station Connectivity

AP1Hey, whathappened to my

settings on AP2!

ConfiguringAP1 is easy!

10.0.0.1


In the lab we will need to take steps to make sure you are configuringand connected to the AP that you think you are!

We will first connect via a wired interface, change the SSID and IP

addressing on the AP, different from what the labs show.

Configuring the IP address on Hosts Ethernet interface

Note: /24 will work because the host still believes it is on

the same subnet as the AP (and visa versa)

Two things to change

Ex: 192.168.1.1/24 Ex: 192.168.1.2/27SSID: AP-Pod1

HostnameNot SSID

224


At the beginning of each lab, after you have connected via the wired Ethernetinterface, you will change the IP Address and SSID on the AP, so the otherLab Station does not accidentally configure yours.

You will also need to change your Hosts IP address.

Cisco AP Factory Default Settings

255.255.255.224 (/27)



26/72

Basic Configuration

The labs will reall hel ou understand this.


27/72

Configure IP address and SSID with IPSU


IP Setup Utility (IPSU) can only change the IP address and SSID of theaccess point from their default settings .

After the IP address and SSID have been changed, IPSU cannot changethem again unless the mode button is held down.

Use a computer on the wired LAN to communicate with the AP through a hubon the wired LAN.

The IPSU must be installed on the computer as well as on the same subnetas the AP.

IPSU uses IP multicast to communicate with the AP

We will not use IPSU.

See 5.2.1 if you are interested.

This feature enables Web-based GUI management by providing support forHTML Web pages and Common Gateway Interface (CGI) scripts usingcommon Web browsers.

The Services>Web Server page is used to enable browsing to the web-basedmanagement system, specify the location of the Help files, and entersettings for a custom-tailored web system for management.

With the Allow Web-based Configuration Management enabled, access to theGUI management system is permitted.

If HTTP is disabled, the management system is accessible only through Telnetor the console

HTTP Help Files


66/72


Hard Drive - The help files can be copied to the hard drive of thecomputer which is used to manage the wireless LAN. Go tohttp://www.cisco.com/public/sw-center/sw-wireless.shtml to downloadthe help files for the particular release. The readme.txt file explains

how to download the help files to the hard drive. This URL starting withfile:// may not be accessible if the security settings of the browser arenot set appropriately. Example:

file://[Drive letter]:\[folder or subdirectory]\wireless\help

Allows Layer 3 Roaming More later.

QoS Not Covered


68/72


QoS is disabled by default. The most important guideline in QoS deployment is to be familiar with

the traffic on the wireless LAN.

It is important to know the applications used by wireless client devices,the delay sensitivity of the applications, and the amount of trafficassociated with the applications.

QoS does not create additional bandwidth for the wireless LAN. Rather it helps control the allocation of bandwidth. If there is adequate

bandwidth on the WLAN, QoS may not be needed.

SNMP Not covered
