Power supply output connectors

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:

vP1 server board main power connector (1 x 24 pin)

vP2 processor power connector (8 pin)

vP3 12-V power connector

vP4 peripheral power connector (2 x 4 pin)

vP5 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.
