The ARX
6000 chassis uses one or two power supplies. When two power
supplies are installed, the power load is shared. The power supplies require a
20 A/220 Vac input cord, which is provided with the chassis. The AC outlet
to the switch must be properly grounded.
Table 5.2 lists the system (fan tray and modules) power consumption.

The total power dissipated by the chassis is the sum of all of the above
divided by 0.88 (the power supply runs at 88% efficiency). Specifically,
