AC Power Supply in the IPS 4300 Series V01 and V02 Chassis
AC Power Supply in the IPS 4300 Series V01 and V02 Chassis
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.
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.

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.

The IDM and JRE 1.7
In IPS versions 7.1(1)E4 through 7.1(5)E4, the IDM fails to connect to the sensor due to a failure during
the initial handshake, because the web server is not RFC 5746-compliant. Try the following workaround.
the initial handshake, because the web server is not RFC 5746-compliant. Try the following workaround.
Problem
Cannot launch the IDM, when the IDM is running under JRE 1.7 with IPS 7.1(1)E4 through
7.1(5)E4.
Solution
Use JRE 1.6 or enable the SSL 2.0-compatible ClientHello format in the Java settings under
Control Panel.
The ASA 5500-X IPS SSP and Memory Usage
For the ASA 5500-X IPS SSP, the memory usage is 93%. The default health thresholds for the sensor
are 80% for yellow and 91% for red, so the sensor health will be shown as red on these platforms even
for normal operating conditions. You can tune the threshold percentage for memory usage so that it reads
more accurately for these platforms by configuring the Memory Usage option in the sensor health
metrics.

Note
Make sure you have the Memory Usage option in the sensor health metrics enabled.
