3.5CONNECTING POWER TO THE 2H22-08R
The 2H22-08R has a primary and redundant power supply. Both power supplies have automatic voltage sensing that allows connection to power sources ranging from 100–125 Vac, 2.0 A or 200–240 Vac, 1.0 A, 50/60 Hz.
To connect the 2H22-08R to the power sources, proceed as follows:
1.Insert the connector of each power cord into the two power supplies and insert the plug of each power cord from the 2H22-08R into a grounded wall outlet, see Figure 3-5. To take advantage of the load sharing and redundancy capabilities, each power cord must be plugged into a dedicated ac outlet. The POWER LED turns on (green) and the CPU LED turns on (green) briefly.
