Figure 9. Power supply unit
Power supply unit voltage operating ranges are nominally 100V - 240V AC,
selected automatically.
The PSU has an audible alarm to indicate a fault state and a bi-color (green/red)
LED to indicate PSU status.
Power supply output connectors
The power supply output connectors provide the following outputs:
v P1 server board main power connector (1 x 24 pin)
v P2 processor power connector (8 pin)
v P3 12-V power connector
v P4 peripheral power connector (2 x 4 pin)
v P5 PSU1 connector (5 pin)
Cooling fans
Ten high-speed single-rotor axial fans are housed in a cooling cage, located
centrally within the enclosure, between the drive bays and the server board, as
shown in Figure 2 on page 3. This ensures maximum airflow through the PSU and
minimizes noise.
