NetScaler MPX

Upgrade the LOM firmware on a NetScaler MPX appliance

Citrix has automated the upgrade of LOM firmware within NetScaler MPX software. It is no longer necessary to know your hardware platform or download any LOM firmware.


This procedure requires two reboots to complete and therefore a disruption in production traffic is expected. Citrix recommends that you perform the upgrade during a maintenance window. In a high availability setup, perform the upgrade on the secondary node to minimize disruption to production traffic. Run the script on the following supported platforms. The script is available in the /netscaler folder.

  • MPX 5900
  • MPX 8900
  • MPX 9100
  • MPX 14000
  • MPX 15000
  • MPX 16000
  • MPX 22000
  • MPX 25000
  • MPX 26000

If you cannot log into the LOM GUI on the MPX 5900, MPX 8900, MPX 15000, or MPX 26000, reset the LOM password by typing shell in the command prompt and then ipmitool user set password 2 <your preferred password> after upgrade to 5.56 or 4.61.


  • Console redirection fails after upgrading the LOM to 4.61 on the MPX 5900 and MPX 8900 platforms or 5.56 on the MPX 15000 and MPX 26000 platforms.
