Connecting a DC Power Supply
Note Both grids in a power redundant system should have the same number of power supplies. If your system is configured for grid redundancy, slots 1 and 2 are assigned to grid 1 and slots 3 and 4 are assigned to grid 2. If only two power supplies (PS) are in a redundant- mode chassis, they should be in slots 1 and 3. Slot and cord connection numbering is shown below.
