Computing MAP Placement 155
7 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. (See “Locking and Unlocking MAP
Access Points” on page 161.)
8 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.
9 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.
10 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.
11 To change the MAP connection type for the redundant connection, select
Direct or Distributed from the MAP Connection Type list.
WX4400 switches support indirect MAP connections only.
12 To change the number of redundant connections for the distributed
connection type, type the number in the Redundant Level box.
13 For direct connections, the redundancy level is always 1.
14 To update all the constraints for the areas you will select in step 15, select
Update All Constraints . By default, 3WXM applies only changed
constraint values to the selected areas. This default behavior preserves
any constraint changes you make to individual areas when you configure
them.
15 Select the coverage areas for which you want to compute and place MAP
access points. To select a coverage area, click the box in the select
column.
