The Apunix Customer Self-Service Appliance does not require periodic maintenance. In fact, as a solid state device without moving parts - not even a cooling fan - the appliance can be expected to provide years of reliable, low-cost, profit-generating service. Power or network interruptions do not require a hardware reboot. If the appliance does experience a malfunction, all that is required is a swap of the appliance box, moving the CompactFlash software load to the new device.
