Troubleshooting appliance power supply problems
NetBackup appliances have two, modular power supplies for high availability
operation. During normal operation, the power supplies are configured for active
standby operation. In this configuration, one power supply is used to provide power
for the entire system and the other is held in reserve. Should the active power supply
fail, the system automatically shifts the load to the power supply that is held in
reserve.
Caution: To ensure power to the system in not interrupted, periodically check the
reserve power supply. Make sure that the unit is turned on and operating properly.
Power supply modules are easily accessed from the rear of the unit. They are
installed side-by-side on the left-hand side of the unit. Each contains an AC socket,
switch, LED, and fan. The LED on the power supply provides information about the
power supply status.
Note: The power supplies are designed to enter protection mode when an electrical
event that is potentially catastrophic occurs. Such events include short-circuits,
voltage overloads, and power surges. In protection mode, the power supply shuts
down or locks up to protect itself and the component in the system.
You can remotely gain information about the current status of an appliance power
supply using one of the following Symantec user interfaces:
■ In the NetBackup Appliance Web Console use Monitor > Hardware page to
view the power supply information.
■ In the NetBackup Appliance Shell Menu use Main_Menu > Monitor > Hardware.
