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 one of the following:
■
For the 5030, use Admin GUI > Monitor > System.
■
For the 5230 use Monitor > Hardware > Power Supply.
■
NetBackup Appliance shell use one of the following:
■
For the 5030 use
support> hwmon show power
■
For the 5230 use
support> monitor >system
You can also gather information about the power supply by viewing the LEDs on
the front and the rear panels of the unit. If the power button and LED on the front
control panel is amber, one or both power supplies may be faulty. Check the LEDs
on the power supplies on the back of the unit to determine which power supply
is faulty. You can use the following procedure to verify that the power supply is
faulty.
To determine if one, or both, power supplies are faulty
1
On the rear panel, locate the power supply that has the amber LED.
2
Make sure that the other power supply functions properly.
3
Unplug the power cord from the power supply that has the amber LED.
4
Wait for 2 minutes or for 3 minutes, then plug in the power cord.
