Installing the WAVE-574
Checking the LEDs
Removing or Replacing a WAVE Appliance
OL-17738-01
While the WAVE appliance is powering up, the green power-on LED on
Note
the front of the appliance is on.
When the WAVE-574 is up and running, observe the front panel LEDs (see
Figure 1-1
and
Table
1-1) to verify that your system is operating properly.
To troubleshoot using the LEDs, see
Hardware."
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.
