Table 14-2 describes the LED activity on the 110 VAC power supply.
DC Power Supplies
The BlackDiamond DC power supplies operate with DC input that can range from -42
to -72 V. Each DC power supply requires a dedicated 60 A service.
The DC inputs are located on the front of the power supply. The input terminals are
isolated from the ground terminal. Power supplies slide in from the front of the chassis,
as illustrated in Figure 14-3.
