Power

Each cell is independently powered. The power system is fully distributed and consists of the following components.

AC Connections

The AC input for each cell is two 15-ampere line cords. The line cords are connected to the power strips mounted in the rear of the cell.

AC/DC Power Supplies

The AC/DC power supplies take the AC input power and produce the DC power used by the cell components. Each cell contains two hot-pluggable AC/DC power supplies. The power supplies are rated for a maximum of 1800 watts at 200 volts or 1000 watts at 100 volts. Actual cell power consumption is significantly less and is determined by the system configuration and activity.

The output of the power supplies is 12 volts with a 3.3-volt keep-alive voltage for power control.

The power supplies are self-cooled.

Figure 2-10 shows the location of the two power supplies on the back of the cell.

Power Supply Indicators

The power supplies have a green LED to indicate the state of the power supply and an amber LED to indicate a fault or failure in the power supply.
