4. Connect the power cords to the power supplies and then to separate power sources.
There can be a maximum of 4 hot-swappable 1133W power supplies. The redundancy scenarios are:
■
1 PSU =
System will not power on
■
2 PSUs = No redundancy
■
3 PSUs = 2 + 1 redundancy
■
4 PSUs = 2 + 2 redundancy
To provide redundancy, connect each power supply to a separate power source.
When power is applied, the SP initializes and the power supply LEDs illuminate. After a few minutes, the
SP login prompt appears on the terminal device. Note that the host is not initialized or powered on yet.

To Power On the System
Use this procedure to apply standby power to the service processor (SP) before initial configuration.
Caution –
Do not operate the server without all fans, component heat sinks, air baffles, and the cover
installed. Severe damage to server components can occur if the server is operated without adequate
cooling mechanisms.
1. Verify that the power cords are connected and that standby power is on.
At this point, standby power is supplied only to the service processor and power supply fans. Do not apply
main power to the rest of the server until you are ready to install a platform operating system. In standby
power mode, the Power/OK LED on the front panel flashes.
2. Use a non-conducting pointed object to press and release the recessed Power button on the front panel.
When main power is applied to the full server, the Power/OK LED next to the Power button illuminates and
remains lit.
