The MPX 17550/19550/20550/21550 appliance has the following ports:

  • 10/100Base-T copper Ethernet Port (RJ45), also called LOM port. You can use this port to remotely monitor and manage the appliance independently of the NetScaler software.
    Note: The LEDs on the LOM port are not operational by design.
  • RS232 serial console port.
  • Two 10/100/1000Base-T copper Ethernet management ports (RJ45), numbered 0/1 and 0/2 from left to right. These ports are used to connect directly to the appliance for system administration functions.
  • Eight 10G SFP+ ports numbered 10/1, 10/2, 10/3, and 10/4 on the top row from left to right, and 10/5, 10/6, 10/7, and 10/8 on the bottom row from left to right.

The following components are visible on the back panel of the MPX 17550/19550/20550/21550 appliance:


  • 160 GB removable solid-state drive that is used to store the NetScaler software.
  • USB port (reserved for a future release).
  • Power switch, which turns off power to the appliance, just as if you were to unplug the power supply. Press the switch for five seconds to turn off the power.
  • Non-maskable interrupt (NMI) button that is used at the request of Technical Support and produces a core dump on the NetScaler. You must use a pen, pencil, or other pointed object to press this red button, which is recessed to prevent unintentional activation.
  • Two removable hard-disk drives that store user data.
  • Disable alarm button. This button is functional only when the appliance has two power supplies.

    Press this button to stop the power alarm from sounding when you have plugged the appliance into only one power outlet or when one power supply is malfunctioning and you want to continue operating the appliance until it is repaired.

  • Two power supplies, each rated at 960 watts, 110-220 volts. Maximum power consumption is 850 watts. Typical power consumption is 570 watts.
