Alarm Information
Log in to ISM and choose Event Management to go to the Faults List page, where the alarms are displayed.

Handling Process
Symptom 1: The system alarm indicator on the front panel of the chassis may remain steady red.

Cause 1: The air intake vent or air exhaust vent is overheated.

1.  Check whether the ambient temperature in the equipment room exceeds 35°C.
  • If the ambient temperature exceeds 35°C, contact the customer to handle the fault.
  • If the ambient temperature is normal, go to step 2.
2.  Log in to the ISM. Select Event Management. In Faults List, view the alarm records to check whether an alarm is generated on the fan module.
  • If fan alarms exist, go to cause 3. If the system alarm indicator is off after the fan alarms are cleared, the fault is rectified.
  • If no alarm is generated on the fan module, contact the technical support engineers of your vendor.
Cause 2: The CPU core is overheated.

1.  Log in to the ISM. In the navigation tree, choose Device Management > Information > Device Information.

2.  Check whether the CPU core is overheated. If the CPU core is overheated, go to step 3.

3.  Open the main control board enclosure top cover. For details, see Opening a Main Control Board Enclosure Top Cover in Replacing a Fan Module.

4.  Take out the air hood.

5.  Fasten the CPU heat sink and reinstall the air hood.

6.  Plug the power cable on the HDP3500E and press the system power switch to power on the HDP3500E. If the system alarm indicator is off after the HDP3500E starts up, the fault is rectified.

7.  If the fault persists, contact the technical support engineers of your vendor.

Cause 3: One or more fans are absent or faulty.

1.  Log in to the ISM. In the navigation tree, choose Device Management > Information > Device Information.

2.  Check whether the fan status is normal. If the fan status is abnormal, go to step 3.

3.  Open the main control board enclosure top cover. For details, see Opening a Main Control Board Enclosure Top Cover in Replacing a Fan Module.

4.  Check whether the five fan indicators are green.

     If a fan indicator is steady red, the corresponding fan is not properly installed or is faulty. Go to Fan Running/Alarm Indicator Is Steady Red.

5.  After handling the fan alarms, if the system alarm indicator turns off, the fault is rectified.

6.  If the fault persists, contact the technical support engineers of your vendor.

Symptom 2: The system alarm indicator on the front panel of the chassis is blinking red.

Cause: The power module is not properly installed or is faulty.

1.  Check the status of the power running/alarm indicators.
  • If the power running/alarm indicators are off, the power input of the power modules are abnormal. The cause may be that the plugs are not properly connected or the power supply in the equipment room is abnormal. Go to step 2.
  • If the power running/alarm indicator is steady orange, an alarm is generated on the power module. Go to Troubleshooting Power Module Faults.
2.  Remove and reinsert the power plugs and check the status of the power running/alarm indicators.
  • If the power running/alarm indicators are blinking green, the power plugs are not properly connected.
  • If the power running/alarm indicators remain off, the power supply in the equipment room is abnormal. Contact the customer.
3.  If the system alarm indicator turns off, the fault is rectified.

4.  If the fault persists, contact the technical support engineers of your vendor.
