Computing MAP Placement 155

6To change the MAP connection type, select the type from the MAP Connection Type list:

„Direct — MAPs are directly attached to dedicated WX switch ports. (Applies to WX1200 switches only.)

„Distributed — MAPs can be indirectly attached through intermediate Layer 2 or Layer 3 devices.

If the MAP access points are directly connected to the WX, ensure that UTP Cat 5 cabling distances between the MAP and the WX in the wiring closet do not exceed 100 meters (330 feet).

An indirectly attached MAP access point requires Power over Ethernet (PoE) from a source other than a WX switch, such as a power injector.

7To allow locked MAP access points to be deleted when Compute and Place determines that they are no longer required, select Allow Deletion of Locked MAPs.

A locked MAP is a MAP that is already associated with the coverage area. For example, if you computed and placed MAPs in this coverage area on a previous occasion and you are now optimizing the plan, the MAPs are still associated with the coverage area. (See “Locking and Unlocking MAP Access Points” on page 162.)

8To change the amount of power to reserve when calculating optimal power, type or select the number of dBm in the Reserved Tx Power Margin listbox. This is the number of dBm below the maximum power setting that you want 3WXM to reserve in case the power needs to be increased later.

9To plan for redundant MAP connections to WX switches, select Compute Redundancy.

Only AP models that have two Ethernet ports can support redundant direct connections. However, models with one Ethernet port can support redundant distributed connections.

10To use the same WX switch for redundant connections, select Use the Same WX for Redundancy.

This option places both of a MAP’s wired connections on the same WX switch. For optimal resiliency, 3Com recommends the use of different WX switches for redundancy.

11To change the MAP connection type for the redundant connection, select Direct or Distributed from the MAP Connection Type list.
