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.

To boot the system from the L1 interface you must have a console connected to the system via the
console port. Use the following commands depending on system type:
1. For a system that contains one IRU, enter the following command at the L1 prompt to power
on the server:
001c01-L1> power up
2. For a system with multiple IRUs, enter the following command at the L1 prompt:
