2: Operation Procedures
Powering On and Off at the Console
The power-on and off procedure at a console varies with your server setup, as follows:
• If you have a console connected to a server with a serial interface, you can toggle between
L1 and console mode. This enables you to power on your server with L1 commands and
view the activity by changing to the console mode.
For detailed instructions on using a system console using the L1 mode, see “Operating the
L1” on page 84.
• If you have a system console connected to a server with an ethernet interface, you can toggle
between L2 and console mode, and power on your server with L2 controller commands, and
monitor the power-on activity by changing to the console mode.
Powering On and Off from the L1
Commands issued at the L1 prompt typically only affect the local IRU. The following sections
describe how to power on and power off your system in L1 mode.
The L1 controller display, located on the front of each IRU, should display L1 running once the
power-on procedure starts (storage modules do not have L1s). The prompt on your console screen
shows the rack and slot number of the IRU to which you have connected your console.
Note: If you have a problem while powering on and an error message appears on your console
display, see “L1 Controller Error Messages” on page 145 to learn what the error message indicates
and how to resolve the problem.
If you want to power on the IRU (001c01 in our example) indicated in the prompt, enter the
following command.
001c01-L1> power up
To power off:
001c01-L1> power down
If you are attempting to power on or power off a system with multiple IRUs from the L1 prompt,
you will need to prepend the command with an asterisk as follows:
oo1c01-L1> * power up
