1.5.2 Operating Power Limits and Ranges
1.5.3 Estimating Power Consumption
To estimate the total power consumption for one or more Sun Fire B1600 blade
system chassis installed in a single rack or cabinet, add together the individual
power requirement figures for each system chassis you have installed, using the
values in
TABLE 1-4
. A minimum system configuration would be:
One blade + one SSC + two PSUs
TABLE 1-3
Operating Power Limits and Ranges
Description Operating Limit or Range
Maximum operating current
*
* Each power cord provides approximately one half of the input current during normal system operation.
16A @ 110 VAC
8A @ 240 VAC
Maximum power supply rating
†
† Currents up to the maximum power supply rating might be required for future product upgrades
12A @ 110 VAC
6A @ 240 VAC
Maximum in-rush current
‡
‡ The in-rush current decays to the normal operating current in less than 200 milliseconds. Sequencing of power
to multiple units is not required, as the peak current is less than seven times the operating current.
20A
Operating input voltage range
(auto-ranging) 110 to 240 VAC
Voltage frequency range 47 to 63 Hz
Power factor 0.8 to 1.0
BTU/Hr rating 3415 BTU/Hr
TABLE 1-4
