Power components
Select AC or DC power supplies according to the power supply mode of your switch.
• Make sure the maximum output power of the power supplies exceeds the system power
consumption. H3C recommends reserving a certain power de-rating value. For the maximum
output power of a single power supply, see Table 38 .
• H3C recommends you to configure N+1 or N+M power supply redundancy.
• To use AC power supply, select the specific 16 A AC power cords. For the 16A AC power cords
used in different countries or regions, see
Table 39 .
• An NEPS3500-A AC power frame can function properly only after you install one or two
NEPS1800-A AC sub power supplies to it.
