Replacing a Power Supply Unit
If a power supply is defected, the Service LED on the disk array unit lights orange.
In addition, the Power Fault LED on the power supply lights orange. The defected
power supply may be replaced with a new one without powering off the disk array unit.
The Power Fault LED lights orange when a battery backup unit is
defected, even if the power supply works normally. Use NEC Storage
Manager to identify the defected unit.
When replacing a power supply, prepare the new power supply before
removing the old one, and then replace it within about 5 minutes. If the
power supply is removed for longer than 5 minutes, the shutdown
sequence is executed by the security feature of the disk array unit.
Read the entire procedure before replacing the power supply.
