Power and Signal Distribution
Table 7-1 lists the specifications of the 240-watt power supply used in the SFF unit.
NOTES:
Total continuous power should not exceed 240 watts. Total surge power (<10 seconds w/duty cycle < 5 %) should not exceed
265 watts.
[1] The minimum current loading figures apply to a PS On start up only.
[2] Maximum surge duration for +12Vcpu is 1 second with 12-volt tolerance +/- 10%.
Table 7-2 lists the specifications for the 320-watt power supply used in the CMT form factor.
NOTES:
Total continuous output power should not exceed 320 watts.
[1] Minimum loading requirements must be met at all times to ensure normal operation and specification compliance.
[2] Maximum surge duration for +12Vcpu is 1 second with 12-volt tolerance +/- 10%.
