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 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 chassis, they should be in slots 1 and 3. Slot and cord connection numbering is shown below.
