About IPMI configuration
The Intelligent Platform Management Interface (or IPMI) provides management and
monitoring capabilities independently of the host system's CPU, firmware, and
operating system. You can configure the IPMI sub-system for your appliances. You
can use the remote management port, located on the rear panel of the appliance,
to connect to the IPMI sub-system.
The following figure shows the remote management port (or the IPMI port) on the
rear panel of a NetBackup 5240 appliance:
IPMI
The IPMI is beneficial after an unexpected power outage shuts down the connected
system. In case the appliance is not accessible after the power is restored, you can
use a laptop or desktop computer to access the appliance remotely by using a
network connection to the hardware rather than to an operating system or login
