Operating Your System

Powering On Manually or With L1 Console

If your system does not have a a local system console, you can manually power on and off the server by using the power button(s).

To power on your system or an individual IRU manually, follow these steps:

1.If the monitors and other peripherals are equipped with voltage select switches, verify that they are set for the appropriate AC voltage and plug them in. Note that they are normally plugged into power sources outside the rack system.

2.Turn the circuit breaker switchs of the PDU to the on position, see Figure 1-20 on page 39.

3.Press the power buttons (see Figure 1-21) on each of the IRUs that you want to power on. Note that any optional storage modules should be powered up first.
