Power and Cooling
This chapter contains information about the power consumption of the Sun Fire
V120 and Netra 120 servers. It also tells you how to estimate the amount of heat that
your cooling system must dissipate.
The chapter contains the following sections:
■ Section 2.1, “Operating Power Limits and Ranges” on page 2-2
■ Section 2.2, “Power Consumption” on page 2-3
■ Section 2.3, “Estimating Heat Dissipation” on page 2-4
Note – The power supply on the Sun Fire V120 server continues to regulate all
outputs for at least 20 milliseconds after AC power is removed. On the Netra 120
server, the power supply continues to regulate all outputs for at least 4.5
milliseconds after DC power is removed.
Note – Standby power is available whenever input power is connected.
