J1103 – Labeled “Hi-Lo” on the PCI riser board, this jumper is reserved for future use.

J1104 – Labeled “WREN” on the PCI riser board, this jumper controls write permissions for the system Boot PROM. In the default position with the shunt covering pins 1 and 2, the system Boot PROM is write-enabled. Moving the shunt to the other position prevents updating the PROM.

About the Power Supplies

A central power distribution board (PDB) delivers DC power to all internal system components. The system’s two standard power supplies—called Power Supply 0 and Power Supply 1—plug in directly to connectors on this board, and all of the supplies installed share equally in satisfying the power demands of the system. AC power is brought into the PDB by way of two board-mounted IEC320 receptacles, each dedicated to one power supply.

The Sun Fire V490 system’s N+1 redundant power supplies are modular units, designed for fast, easy installation or removal, even while the system is fully operational. Power supplies are installed in bays at the front of the system, as shown in the following figure.

The power supplies operate over an AC input range of 200–240 VAC, 50–60 Hz, without user intervention. The power supplies are capable of providing up to 1448 watts of DC power. The basic system configuration comes with two power supplies installed, either of which is capable of providing sufficient power for a maximally configured system.
