The following components are visible on the back panel of the SDX 25100A and SDX 25160A appliance:

  • Two 300 GB removable solid-state drives (SSDs). The two leftmost solid-state drives store the NetScaler software. The next two solid-state drives store user data. The remaining four solid-state drives are reserved for future use. These appliances are a redundant array of independent disks (RAID) devices.

    Note: Drive densities might increase as components become EOL but its size is never smaller than the original.

  • Power switch. Which turns power to the appliance on or off. Press the switch for less than two seconds to shut off the power.
  • Two power supplies. each rated at 1000 watts, 100–240 volts. Each power supply has an LED that indicates the status of the power supply.
  • Disable alarm button. Which is functional only when the appliance has dual redundant, hot-swappable power supplies. Press this button to silence the power alarm when one of the two power supplies loses input power or when a power supply is malfunctioning.
  • Non-maskable interrupt (NMI) button. Used at the request of Technical Support to initiate a core dump. To press this red button, which is recessed to prevent unintentional activation, use a pen, pencil, or other pointed object. The NMI Button is also available remotely over the network in the LOM GUI, in the Remote Control menu.
