Hardware
This chapter describes physical installation and maintenance of DarkStar hardware components.
2.1 Power
DarkStar systems ship with two power supply modules, which, under normal conditions, operate as distributed sources. In the
event that one power module fails, the system can operate on a single power module. Power supply modules are hot
swappable, and therefore can be replaced while the DarkStar system is running.
Follow the instructions in Figure 2.2, “Replacing Power Supply Modules,” on page 11 for power supply module replacement
procedures.
The general procedure for managing power supply modules is the same for all systems. Power supply modules use either AC
or DC power.
2.1.1 Power Requirements
For maximum availability, DarkStar systems should be connected to two power circuits. The circuits may be AC, DC, or a
combination of AC and DC power. The following power combinations are supported:
•
Two 100-240VAC.
•
Two 48VDC.
•
One 100-240VAC and one 48VDC.
2.1.2 AC Power
DarkStar products with AC power require no special wiring and can be connected to a standard outlet with 100-240VAC power
using the included power cords.
2.1.3 DC Power
To install DarkStar products configured for DC power, 12-16 AWG (American Wire Gauge) stranded wire is recommended.
However, 14 AWG wire is optimal for its size and flexibility.
There are two styles of DC power connectors on DarkStar systems. Reference the following illustrations to determine which
style is installed on a DarkStar system.
