To remove a WAVE appliance from your network, power it down, disconnect the power cords and 
network cables, and physically remove the chassis from the rack.

The WAVE appliance is in constant communication with the router on your network. When the router 
notices that the WAVE appliance is no longer responding to it, the router stops sending requests to the 
WAVE appliance. This action is transparent to users. If other WAVE appliances are attached to the router, 
the router continues sending requests to the other WAVE appliances.

When you remove a WAVE appliance, the pages that were cached on that appliance 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 support on the 
router. However, this action is not necessary because leaving WAVE 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.
