IPMI requires compatible hardware! Refer to your hardware documentation to determine if this option will appear in the TrueNAS web interface.

Many TrueNAS Storage Arrays provide a built-in out-of-band management port which can be used to provide side-band management should the system become unavailable through the web interface. This allows for a few vital functions, such as checking the log, accessing the BIOS setup, and powering on the system without requiring physical access to the system. It can also be used to allow another person remote access to the system to assist with a configuration or troubleshooting issue.

Some IPMI implementations require updates to work with newer versions of Java. See PSA: Java 8 Update 131 breaks ASRock’s IPMI Virtual console for more information.


IPMI is configured from Network > IPMI. The IPMI configuration screen provides a shortcut to the most basic IPMI configuration.

IPMI Configuration

These options are available:

SettingValueDescription
TrueNAS Controllerdrop-down menuSelect a TrueNAS controller. All IPMI changes are applied to that TrueNAS controller.
Channeldrop-down menuSelect the communications channel to use. Available channel numbers vary by hardware.
PasswordstringEnter the password used to connect to the IPMI interface from a web browser. The maximum length accepted in the UI is 20 characters, but different hardware might require shorter passwords.
DHCPcheckboxIf left unset, IPv4 Address, IPv4 Netmask, and Ipv4 Default Gateway must be set.
IPv4 AddressstringIP address used to connect to the IPMI web interface.
IPv4 Netmaskdrop-down menuSubnet mask associated with the IP address.
IPv4 Default GatewaystringDefault gateway associated with the IP address.
VLAN IDstringEnter the VLAN identifier if the IPMI out-of-band management interface is not on the same VLAN as management networking.
IDENTIFY LIGHTbuttonShow a dialog to activate an IPMI identify light on the compatible connected hardware.

IPMI Options

After saving the configuration, the IPMI interface is accessed using a web browser and the IP address specified in Network > IPMI. The management interface prompts for login credentials. Refer to your IPMI device documentation to learn the default administrator account credentials.

After logging in to the management interface, the default administrative user name can be changed and additional IPMI users created. The appearance of the IPMI utility and the functions that are available vary by hardware.
