Routine Maintenance


Issue 01 (2011-07-15)

Context

Sensors are used to collect monitored environment parameters, such as temperature and waterleakage.

The sensors are classified into the following types: temperature and humidity sensor, door statussensor, smoke sensor, water sensor, main distribution frame (MDF) sensor, surge protectorsensor, battery temperature sensor, and other sensors used by operators.

Reference Standard

When the environment where an alarm is generated is stimulated, the alarm can be reported andqueried on the U2000. For information on how to query alarms on the U2000, see MonitoringCritical and Major Alarms of Devices.

Procedure

Step 1 Simulate the environment where an alarm is generated on site. The following examples areprovided for reference.

l In the case of a temperature sensor, decrease the threshold of the temperature alarm tosimulate an over-temperature alarm.

l In the case of a smoke sensor, make some smoke to generate a smoke alarm.

l In the case of a door status sensor, open the cabinet door to generate a cabinet door statusalarm.

CAUTIONThe alarm environment must be simulated without interrupting the ongoing services.

Step 2 Check whether the corresponding environment alarms are reported to the U2000.

Step 3 If no environment alarms are reported to the U2000, the hardware of sensors is abnormal. Handlethe fault according to "Exception Handling" until the fault is rectified.

----End

Exception Handlingl Replace the faulty sensors until the corresponding environment alarms can be reported and

queried on the U2000.

l If the fault persists, contact Huawei technical support engineers. For details, see 1.3 Howto Obtain Technical Support from Huawei.
