Operating voltage
Nominal -48V DC, Range -44 to -72V DC
Nominal -48V DC, Range -44 to -72V
DC
115V AC, Range 100V to 240V, 47 to
63 Hz
Note: Once powered up, the C4 and C4c CMTS will continue to operate if within this range.
Start-up voltage range
-44 to -67.5V DC
-44 to -67.5V DC
Note: If powered down, the C4 and C4c CMTS will not restart successfully if the voltage is not in the range of -44 to -
67.5V DC. This offset from the operating range provides a cushion against multiple possible power cycles. Attempted
start-ups at the voltage extremes are subject ot power fluctuations that could result in multiple power cycles and
damage to the equipment. The -44 V guaranteed operating limit translates to a maximum current draw of 64A at
2800W.
Chassis power consumption
2800 W maximum
1200 W maximum using DC power
1350 W maximum using AC power
