9.2.2 Problems that occur after OS startup

(1) The alarm lamp is lit and the digital LEDs for status indications show alphanumeric characters. Alternatively, only
the digital LEDs for status indications show alphanumeric characters.
Possible cause
This is a hardware error notification from the RAS software, or is being displayed by a user application.
Action
1. If one of the status indication LEDs is lit in red, this is a hardware error notification from the RAS software.
Check the characters displayed on the digital LEDs for status indications.
● If 12 or 13 is displayed on the digital LEDs for status indications:
The rotation of a fan is abnormal. (12 indicates a system fan failure, and 13 indicates a CPU fan failure.)
Check the following items:
i) Make sure that no foreign objects are attached to the fan.
If any foreign objects are attached, the cooling efficiency inside the equipment becomes is reduced.
Remove any foreign objects.
ii) Make sure that the power cord for the fan is connected to a power connector.
A loose connection might have caused the symptom. Remove the power cord for the fan from the
power connector, and then reconnect it.
● If 21 is displayed on the digital LEDs for status indications:
The temperature is abnormal. Check the following items:
i) Make sure that the dust filter at the front of the equipment and the exhaust outlet at the rear are not
clogged.
If they are clogged, clean the dust filter and the air intake and exhaust holes. If necessary, replace the
dust filter.
ii) Make sure that sufficient clearance is provided around the equipment. (See 1.6.2 Installation.)
If clearance is insufficient, provide sufficient clearance around the equipment.
iii) Make sure that the temperature of the installation environment (the ambient temperature) is less than
40ºC.
Remove obstacles to airflow or use air-conditioning to keep the ambient temperature lower than
40ºC.
● If 31 or 32 is displayed on the digital LEDs for status indications:
A failure is predicted for the drive in drive bay. (31 indicates drive bay 1 and 32 indicates the drive bay 2.)
We recommend that you back up the data on the drive and replace the drive.
