Lights out management port of the NetScaler SDX appliance

Last published : Oct 01, 2026
The SDX ADC appliances have an Intelligent Platform Management Interface (IPMI), also known as the lights out management (LOM) port, on the front panel of the appliance. You can use the LOM port to remotely monitor and manage the appliance, independently of the NetScaler software.
By connecting the LOM port to a dedicated channel that is separate from the data channel, you can make sure that connectivity to the appliance is maintained even if the data network is down. Further you can reduce the data cable and data network as a single point of failure.
You can access the LOM port through a browser and use the GUI for most tasks. All tasks can be performed through the NetScaler shell.
You can use either the GUI or a shell for the following tasks:
  • Configuring the network settings
  • Health monitoring
  • Power control operations
  • Factory reset
Different NetScaler® ADC appliances support different shells:
  • For Citrix Hypervisor based NetScaler SDX appliances, use the dom0 Linux root shell. To access the dom0 shell, log on to the Citrix Hypervisor management IP address instead of the SDX Management Service IP address, using the root account, not the nsroot account.
  • For Linux based appliances, use the Linux bash root shell.
Note
The terms LOM and Baseboard Management Controller (BMC) are used interchangeably.
Caution: LOM firmware versions are platform specific. Upgrading to a LOM firmware version other than the one shown for your platform in the LOM support matrix table, might result in the LOM becoming unusable.

Upgrade LOM version to 3.11.0

Starting from release 13.1 build 58.x and release 14.1 build 43.x, LOM version 3.11.0 is available for the following platforms. This version addresses multiple functional issues.
  • SDX 9100
  • SDX 16000

Upgrade procedure

  1. Login to dom0 Linux root shell.
  2. Run the following command:
    echo "3.11" > /opt/xensource/packages/files/sdx-lom/platforms/matua/version
  3. In the Management Service user interface, navigate to the Configuration > System.
  4. Click Reboot Appliance.

Configuration compatibility

The LOM configuration format is not compatible between the 2.12.12 and 2.13.12 LOM versions and the new 3.11.00 LOM version.
You might lose some LOM configurations during the upgrade process from the 2.12.12 or 2.13.12 version to the new LOM 3.11.00 version. Once the upgrade is complete, you cannot use any manually created LOM 2.12.12 or 2.13.12 version configuration backups to restore the configuration.
Note
We recommend saving the current LOM configuration before the upgrade. By saving the LOM configuration you can manually reapply any missing settings afterwards.
The upgrade process does not retain all the LOM configuration settings; manual reapplication might be necessary in the following areas:
  • Manually created local LOM user accounts (specifically, all accounts except the default ns root account).
  • RADIUS server shared a secret.
  • Password for LDAP authentication.
  • SMTP password in the Notifications > SMTP section.
  • Authentication key and encryption key for SNMPv3 alerts in the Notifications > Alerts section.
  • The SNMPv1 alert Trap Community string in the Notifications > Alerts section.
  • Any SNMP settings in the Notifications > SNMP section.
