ISSUE RESOLUTION
The Emergency Ventilation Fans activate
for no apparent reason.
• Validate that the SmartRow DCR iCOM-control settings are entered as instructed for the
SmartRow DCR.
• See Liebert iCOM™ Controls Set-up on page 55 for additional details.
The temperature in one of the racks is too
warm/cold.
• Adjust the damper in the bottom of the rack until the desired temperature is achieved. You
may need to adjust the damper in neighboring racks slightly to help balance the airflow in
the system.
• See Adjusting Air-flow Adjustment Dampers on page 42 for additional details.
• Do not exceed 6 kW of heat load in a given rack.
• Ensure that the heat load is reasonably distributed across all of the racks.
• Validate that the SmartRow DCR iCOM-control settings are entered as instructed in the
SmartRow DCR.
• See Liebert iCOM™ Controls Set-up on page 55 in for additional details.
The cooling unit is short cycling (turning on
and off frequently).
• Close the air damper in racks that have no IT equipment.
• Ensure blanking panels are installed in any empty U-space to prevent cold air supply
bypassing directly into the return air stream.
• Make sure that there is at least 4 kW of heat load in the 20-kW SmartRow, 8 kW in the
36-kW system.
• Do not exceed 6 kW of heat in a single rack.
• If using a 20-kW (N+1) or 36-kW (N) configuration, the iCOM controls of the thermal-
management units must be set for Teamwork mode.
