The Cisco IPS 4300 series sensors with the AC power supply can restore the previous power state of the 
system if AC power is lost. Earlier IPS 4300s (V01) require you to turn on the power with the power 
switch. Newer IPS 4300s (V02) automatically turn on when you plug in the power cable. 

To determine your version, do one of the following:

At the CLI, enter the show inventory command and look for V01 or V02 in the output.

On the back of the chassis, look at the VID PID label for V01 or V02.

The V01 chassis has the following limitations (these limitations do not apply to the V02 chassis):

The sensor requires 50 seconds from the time that AC power is applied before the power state can 
be updated and stored. This means that any changes to the power state within the first 50 seconds of 
applying AC power will not be observed if AC power is removed within that time.

The sensor requires 10 seconds from the time it is placed into standby mode before the power state 
can be updated and stored. This means any changes to the power state within the first 10 seconds of 
entering standby mode (including the standby mode itself) will not be observed if AC power is 
removed within that time.
