ATCA Power Module (−48V to 12V)
The Sun Netra CP3060 blade server uses the ATCA power module solution. The
power module provides integrated ATCA power solution which supports PCIMG3.0
requirements including dual bus input, DC isolation, hold up, hot-plug, and
management power (3.3V standby). It provides 12V intermediate bus as backend
power. Some of the salient features of the module are:
210W output power
■
Input-to-Output Isolation
■
12V with current rating of 17.5A
■
3.3V standby at 1.82A. System Management Controller draws power from IPMI
■
Power (3.3V_STBY) so that it can be functional even if back end logic is powered
down.
Isolated Remote ON/OFF
■
Isolated A and B Bus detect signals
■
Operating Input Voltage: −36V to −72V
■

On-Board DC/DC Regulators
The Sun Netra CP3060 blade server uses its own designed DC/DC SIP modules for
generating other onboard power. All the voltages are generated from +12V input
power.
