A process chamber includes a wafer support to mount a wafer to be processed in the process chamber, with the wafer having an annular edge exclusion area. The system may adapt to delays by using other mechanisms to convey the information intended for delivery by e-mail. Vertical support posts are detachably secured at a bottom portion to an associated bearing plate and extend upwardly through an associated opening in the second deck. A second transaction log based on a second execution of the virtual network using the test traffic and a second set of policies to be implemented in the production network can be obtained. The heat sink is supported by the supporting portion.
