Converting to Managed Access Point Operation

3CRWE875075A
When shipped from the factory, 3Com 7250, 8250 and 8750 Access Points are configured for
autonomous operation (also known as standalone or FAT operation). However, these access points can
also be configured as Managed Access Points (MAPs) for use with the 3Com Wireless Switches. This
document describes how these access points can be configured as MAPs.
Topics covered in this document include:
Requirements
Autonomous Operation Versus MAP Operation
Understanding the MAP Conversion Process
Performing the MAP Conversion Process
Viewing LEDs in MAP Operation
Using the Reset Button in MAP Operation
Reverting a MAP to Autonomous Operation
Requirements
Converting a 3Com autonomous access point to a MAP requires the following:
Mobility System Software version 3.2 or greater
3WXM version 3.2 or greater
MAP Conversion Software
The above software files are available for download from the 3Com eSupport website at:
www.3com.com/support.
Autonomous Operation Versus MAP Operation
When the access point is operating in MAP mode, some functionality is transferred from the access point
to the Wireless Switch. This provides for better mobility within the wireless coverage area and allows the
coverage area to be monitored in order to detect rogue access points.
Some of the functional differences between an autonomous access point and a MAP are:
The MAP configuration is done through 3WXM (or the Wireless Switch). The MAP does
not store any configuration. This makes it easier to reconfigure the wireless network.
Any configuration that the access point had prior to the conversion to MAP mode is lost.

Summary of Contents for 3Com 3CRWE825075A

  • Page 1 (also known as standalone or FAT operation). However, these access points can also be configured as Managed Access Points (MAPs) for use with the 3Com Wireless Switches. This document describes how these access points can be configured as MAPs.
  • Page 2 Wireless Switch. NOTE: The console port on the access point is not used when running in MAP mode. 3Com recommends that you remove any console cables from the access point after the conversion to MAP operation.
  • Page 3 How the MAP Locates a Wireless Switch After an access point is converted to a MAP, it goes through a process to locate a Wireless Switch. This section describes the complete boot and configuration process used by Distributed MAPs in MSS Version 3.2 to locate a Wireless Switch.
  • Page 4 If the MAP does not find a Wireless Switch using the Find WX broadcast method, and the DHCP Ack message contained a list of Wireless Switch IP addresses or hostnames in DHCP option 43, the MAP contacts the Wireless Switches: If the DHCP Ack message contained a list of IP addresses, in DHCP option 43, the MAP sends a unicast Find WX message to each address.
  • Page 5 MAP Conversion Software installed on a PC. This software is available on the CD that is provided with the Wireless Switch; it may also be downloaded from the 3Com web site at www.3com.com. Conversion in a Stand-Alone Network This section assumes that you are converting an access point that has its factory default settings.
  • Page 6 IP address of the access point in the address bar. Otherwise follow steps 4 to 6 to find the device and launch the web management interface. Launch the 3Com Wireless Infrastructure Device Manager, select the network adapter (if required) and refresh the display. The PC needs to be connected to the same subnetwork as the access points to be converted.
  • Page 7 For example: If the access point is powered on but is not connected (directly or through a network) to a 3Com Wireless Switch, the Power LED will flash yellow when in MAP mode and will be lit green when in autonomous mode.
  • Page 8 This default image provides limited functionality but allows the 3Com Wireless Infrastructure Device Manager to access it and provide a new runtime image. The reversion process works by deleting the MAP runtime image. The access point then boots the default image.
  • Page 9 The Power LED should light green. If it does not, repeat step 2. It sometimes can be difficult to keep the Reset button depressed on the AP8250 and AP8750. Launch the 3Com Wireless Infrastructure Device Manager, select the network adapter (if required) and refresh the display. The PC needs to be connected to the same subnetwork as the access points that is being reverted.
