Maintenance of the
RF Sensor
Java Update
Problems
26
The RF Sensor is designed to be very low maintenance. The Sensor has no
user-serviceable components; nor does it have any physically accessible
adjustments. Do not open the sensor case.
To maintain the RF sensor, it should be checked occasionally to verify that it
has not accumulated excessive dust, dirt, or sand. It should be cleaned of any
bird droppings with a damp cloth. Ensure that the cooling fins are not blocked
by twigs or wind-borne debris.
If an AC power supply cord requires replacement, only use a cord rated for the
proper voltage and current, and one that has a safety agency approval mark
appropriate for the country of installation. Contact Keysight Technologies for
a suitable replacement cord set.
Symptoms
If the SMS and SMT have been working fine, then, after updating Java, while
SMS and/or SMT are running, it is possible Java will not finish its update,
causing it to work incorrectly. In this state, SMS and SMT will not work.
Recommend Procedure to fix broken Java
SMS must be stopped before running a Java update. To fix Java and keep it up
to date, manually re-run the Java 6 update 33 installer, while SMS is stopped.
