Technical Reference Guide 361834-001 7-3
Power and Signal Distribution
NOTES:
Total continuous power should not exceed 300 watts. Total continuous power (excluding 5 V aux output) should not exceed 290
watts
[1] Minimum loading requirements must be met at all times to ensure normal operation and specification compliance.
[2] Surge duration no longer than 10 seconds with 12-volt tolerance +/- 10%.
Table 7-4 lists the specifications for the 340-watt power supply used in the CMT form factor and
in some MT form factors.
NOTES:
Total continuous output power should no exceed 340 watts. Maximum surge power should not exceed 360 watts. Total
continuous power (excluding 5 V aux output) should not exceed 325watts.
Maximum combined power of +5 and +3.3 VDC is 160 watts.
[1] Minimum loading requirements must be met at all times to ensure normal operation and specification compliance.
[2] Surge duration no longer than 10 seconds with 12-volt tolerance +/- 10%.
