The following tables list the maximum electrical power for the N6200 series
systems and the electrical requirements for different configurations of the N6200
series systems.
Table 4. N6200 series systems maximum electrical power
System Maximum electrical power
N6200 series systems 100-240 V ac, 12-8 A, 50-60 Hz.
In the following tables, Worst-case indicates a system running with one PSU and
high fan speed. Typical Per PSU/System, two PSUs indicates a system running one
PSU on one circuit and a system running two PSUs on two circuits.
Note: Electrical requirements for systems containing performance accelerator, Flash
Cache, and Flash Cache 2 modules are measured with the maximum number of
these modules installed in the system. The maximum power draw is 25W.
