Statement 1040
To remove a WAE from your network, power it down, disconnect the power cords
and network cables, and physically remove the chassis from the rack.
The WAE is in constant communication with the router on your network. When
the router notices that the WAE is no longer responding to it, the router stops
sending requests to the WAE. This is transparent to users. If other WAEs are
attached to the router, the router continues sending requests to the other WAEs.
When you remove a WAE, the pages that were cached on that device are no longer
available to the router or other WAEs. You might see an increase in outgoing web
traffic that might have otherwise been fulfilled by the WAE that you are removing.
However, after a time, the router and other WAEs redistribute the load of web
traffic.
