Removing and replacing a NetBackup 5220 Appliance
power supply
The NetBackup 5220 Appliance has two power supplies to provide fault-tolerant
operation. If one power supply fails, the other provides power to the appliance until
the faulty power supply is replaced.
Power supplies are hot swappable. You can replace one while the appliance is in
operation. At least one power supply must be functioning for the appliance to
operate.
Caution: Do not leave a power supply bay empty for longer than 3 minutes. The
NetBackup 5220 appliance is constructed for optimum air circulation when the unit
is in operation. The appliance can overheat and damage vital components if a power
supply bay is empty for longer than three minutes while the appliance is in operation.
