Power supply units defective
Ê
Check the LEDs of the power supply units.
If the operating indication (green LED) on the power supply units is dark and
the fault indication (amber LED) is on, the power supply units are defective.
Ê
Replace the power supply units.
11.1.1.2 Power supply status indicator lights yellow
One of the installed power supply units has failed.
Ê
Check which one of the power supply units has failed. If only the amber LED
is on, the power supply unit is defective or the power supply don’t receive
power.
Ê
Replace the defective power supply unit (see section “Replacing the Power
Supply Unit” on page 30).
The problem is cleared if:
–
the green LED on the power supply unit is ON and
–
the power supply status indicator on the front of the storage subsystem
lights green.
11.1.1.3 Power supply status indicator lights orange
The device is switched OFF and in the standby mode.
Ê
Switch the device ON (see section “Switching the Storage Subsystem
ON/OFF” on page 69).
Ê
If the LED remains orange, the power supply units may have failed. Replace
the power supply units. If the LED then still remains orange, contact our
Service organization.
