148 CHAPTER 4: PLANNING THE 3COM MOBILITY SYSTEM
14 To change the MAP connection type, select the type from the MAP
Connection Type list:
Direct — MAPs are directly attached to dedicated WX switch ports.
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.
15 To 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.
16 To 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.
17 To 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.
18 To 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.
19 To change the MAP connection type for the redundant connection, select
Direct or Distributed from the MAP Connection Type list.
WX4400 switches support distributed MAP connections only.
