Power Supply Output Cables; Cooling Module; Figure 8. Cooling Module - Intel SSR212CC User Manual

Power supply module replacement must be completed within 30 seconds of removal of
the failed power supply module.

Power Supply Output Cables

The power supply output cables provide the following outputs:
•
Backplane power connector, including Power Good and Power Fail
•
Server board power connectors (1 x 24 pin, 1 x 8 pin)
•
1 x 4-pin power sockets for internal peripheral power (not used)
•
1 x 5 power signal cable

Cooling Module

The cooling module consists of three high-speed dual-rotor axial fans and two single-rotor
axial fans, mounted in a common frame for ease of maintenance. The fans are mounted in
a single fan tray in the center of the enclosure; this ensures maximum airflow through the
power supply unit and minimizes noise. The single interface to the cooling module
provides power and speed control to the fans and returns tacho output from each fan.
Airflow is front to rear with cooling air being drawn across the drives, through the fans
and pressurizing the rear of the enclosure. The pressurized rear allows the power supply
unit to draw the air that it requires, and perforations at the rear of the chassis allow cooling
airflow over the processor heatsinks, server board and PCI cards.
The cooling system must be operated with low-pressure rear exhaust installation [Back
pressure created by rack doors and obstacles not to exceed 5 pascals (0.5-mm water
gauge)].
The cooling system provides sufficient capacity to ensure that drive maximum
temperatures are not exceeded at 35°C ambient with one fan failed at 7,000 ft.
