Lights Out Management Port of the NetScaler SDX Appliance

Jan 28, 2011

The SDX 8005/8015/8200/8400/8600/8800, SDX 11500/13500/14500/16500/18500/20500, SDX 17550/19550/20550/21550, SDX 22040/22060/22080/22100/22120, and SDX 24100/24150 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. You thereby eliminate the data cable and data network as a single point of failure.

You can access the LOM port through a browser and use the graphical user interface (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 Citrix appliances support different shells:
  • For XenServer based NetScaler SDX and CloudBridge appliances, use the dom0 Linux root shell. To access the dom0 shell, log on to the XenServer 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.
Important: With BMC version 3.xx or later, should the LOM port fail, its functions are switched over to the management port (0/1). In this shared mode, the management port can support both the BMC MAC address and the interface 0/1 MAC address on the same network cable.
Caution: LOM firmware versions are platform specific. Upgrading to a LOM firmware version other than one shown for your platform in the LOM Support Matrix, below, results in the LOM becoming unusable.

The LOM Support Matrix shows the LOM firmware versions shipped with the various platforms, along with the recommended versions, and the earliest NetScaler software versions that support both the shipped and the recommended LOM firmware versions. The latest available LOM package can be found on the Citrix downloads website under LOM Firmware Upgrade.
