3.5 CONNECTING POWER TO THE 2H22-08R
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.
