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.)
Input voltage: -48 Vdc
Component Power (Watts)
Typical Maximum
System Control Module (SCM) 160 W 179 W
Network Services Module (NSM) 125 W 137 W
Adaptive Services Module (ASM) 210 W 237 W
Fan Tray (6 fans + fan controller) 105 W 176 W
