8 Under the Constraints tab, you can do the following:
To change the ceiling height, specify the new height in the Height of
the Ceiling box.
To change the height where MAPs are mounted, specify the new
mounting height in the AP Placement Height box.
To change the WX switch model, select the model from the WX
Model list.
To change the default MAP model, select the model from the Default
AP Model list.
To change the MAP connection type, select the type from the AP
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.
Distributed (Auto)—MAPs can be indirectly attached through
intermediate Layer 2 or Layer 3 devices. They receive their
configuration automatically using a profile that assigns a
Distributed MAP number and name to the MAP from among the
unused valid MAP numbers available on the switch. The profile also
configures the MAP with the MAP and radio parameter settings in
the profile.
To allow locked MAP access points to be deleted when the Compute
and Place function 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.
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 Under the Redundancy tab, you can do the following:
To plan for redundant MAP connections to WX switches, select
Compute Redundancy.
