System Power Requirements

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,

Hardware module dimensions (SCM,

ASM, NSM)

Height: 15.25 in. (38.74 cm)

Width: 1.75 in. (4.45 cm)

Depth: 20 in. (50.8 cm)

Hardware module power

(SCM, ASM, NSM)

(See Table 5.2

for power

consumption information.)
