1.This recommendation is based on normal memory usage within the switch.

2.PXM45, which is the first released version of the PXM45 card and is sometimes called PXM45A, is not supported on Release 5 switches.

3.Connections limits are calculated differently for a switch and for CWM. For more information, refer to the following section, “Connection Limit Adjustments.”
