Step 19. Connect the Power Cords
Plug the power cords for the display, and attached devices into electrical outlets.
If redundant power is required, ensure that there are at least two type-7 power distribution buses (PDBs)
installed in the rack. These PDBs must be connected to two separate ac power sources. To ensure
adequate power, the 7038 Model 6M2 must be connected to type-7 PDBs.
Note: For information about connecting power cables to the PDUs in the rack, refer to the 7014 Model
T00 Rack Installation and Service Guide , order number SA38-0577, and Site and Hardware
Planning Information , order number SA38-0508.
Plug the power cords for the processor subsystem into the type-7 PDBs that supply power to the rack.
When the power cords are plugged into the PDBs, the operator panel displays

LED (1) blinks. When this occurs, your system is in standby mode. The following illustration shows the
