Cabling the Server
Connect the server power cables, and external cables in the following order:
1. Connect two grounded server power cords to grounded electrical outlets (1, 2).
Note – Connect only one cable if your server does not have a redundant power
supply.
2. Connect the two server power cords to the AC power connectors on the back panel
of the server.
In standby power mode, the Power/OK LED on the front panel flashes, indicating
that the service processor (SP) is working as shown in FIGURE 3-2. At this point, before
initial configuration, standby power is supplied only to the SP and power supply fans.
