Citrix ADC MPX
The following components are visible on the back panel of the MPX 25100A, MPX 25160A, and MPX
25200A:
• Two 300 GB or larger removable solid‑state drives in a redundant array of independent disks
(RAID) devices. In a RAID configuration, the same data is stored on multiple drives to improve
performance, increase storage capacity, lower the risk of data loss, and provide fault tolerance.
The two SSDs store the same data. If one fails and you replace it, the new SSD mirrors the other
one.
Note: Drive densities might increase as components become EOL but its size is never smaller
than the original.
• Power switch. This switch turns the power to the appliance on or o. Press the switch for less
than two seconds to shut o the power.
• Two power supplies. Each power supply is rated at 1000 watts, 100–240 volts. Each power sup‑
ply has an LED that indicates the status of the power supply, as described in Common hardware
components.
• Disable alarm button. This button is functional only when the appliance has two power sup‑
plies. 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.
• Non‑maskable interrupt (NMI) button. This button is 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. For more information about the
lights out management port of the appliance, see Lights out management port of the Citrix ADC
MPX appliance.
