When you remove a WAVE appliance, the pages that were cached on that device
are no longer available to the router or other WAVE appliances. You might see an
increase in outgoing web traffic that might have otherwise been fulfilled by the
WAVE appliance that you are removing. However, after a time, the router and
other WAVE appliances redistribute the load of web traffic.
If you remove the last WAVE appliance from your network, you can also disable
WAVE appliance support on the router. However, this action is not necessary
because leaving WAVE appliance support enabled when there are no WAVE
appliances attached has no effect on the router’s performance.
To replace a WAVE appliance, remove it from the network, and then install a new
WAVE appliance and configure it using the same configuration parameters (IP
address and so forth) that you used for the removed WAVE appliance.
