Solution:

1.

Verify water supply and that the MCS unit is receiving water.

2.

Verify that the High Temperature Emergency Door Opening Threshold is not less than 5°C (41°F)
above or more than 20°C (68°F) above the Server Intake Temperature Set Point, or that it is not

below the Water Flow Loss Emergency Door Opening Temperature Threshold.

3.

Adjust the temperature in the Server Intake Temperature Set Point or the Water Flow Loss Emergency
Door Opening Temperature Threshold fields to prevent false alarms.

IMPORTANT:

Use caution when entering temperatures in the Emergency Door Opening fields.

Setting the temperature thresholds too low might cause the MCS unit to shut down.

Solution:

1.

Look for leaks or determine if condensation is the cause.

2.

If no leaks are found, adjust the temperature in the Excessive Moisture: Condensation Pump Cycles
Warning Threshold field.

IMPORTANT:

Use caution when entering temperatures in the Condensation Pump Threshold

fields. Be sure to determine the proper default settings to prevent false alarms, without masking

problems with the MCS.
Default settings will vary, depending on the humidity level of your data center and the heat

load generated by the equipment in the MCS.
