Chapter 1 Introduction to the Hardware Platforms

Field Replaceable Units

Citrix NetScaler field replaceable units (FRU) are NetScaler components that can be quickly and easily removed from the appliance and replaced by the user or a technician at the user's site. The FRUs in a NetScaler appliance can include a CompactFlash card, DC or AC power supplies, and solid-state or hard-disk drives, and a direct attach cable (DAC).

Note: The solid-state or hard-disk drive stores your configuration information, which has to be restored from a backup after replacing the unit.

Power Supply

For appliances containing two power supplies, the second power supply acts as a backup. The MPX 22040/22060/22080/22100/22120 can accommodate four power supplies, and require two power supplies for proper operation. The third and fourth power supplies act as backup.

The appliance ships with a standard power cord that plugs into the appliance’s power supply and an NEMA 5-15 plug on the other end for connecting to the power outlet on the rack or in the wall.

For power-supply specifications, see "Hardware Platforms," which describes the various platforms and includes a table summarizing the hardware specifications.

Note: If you suspect that a power-supply fan is not working, please see the description of your platform. On some platforms, what appears to be the fan does not turn, and the actual fan turns only when necessary.

For each power supply, a bicolor LED indicator shows the condition of the power supply. The LEDs of the AC power supplies for MPX 15000 and 17000 appliances are different from the LEDs of the other appliances.
