Powering the System On and Off

Powering Off at the System Console
The power-off procedure at a system console varies with your server setup, as follows:
• If you have a system console connected to a server with an ethernet or other
hardware interface, you can toggle between L1 and console mode, power off your
server with L1 controller commands, and monitor the power-off activity by
changing to the console mode.
• If your system console is running on a server via a serial interface connection, you
can also toggle between L1 and console mode. This enables you to power off your
server with L1 commands and view the activity by changing to the console mode.
For detailed instructions on using a system console in the L1 mode, see “Operating
the L1” in Chapter 2.
The following instructions describe how to power off your system in the L1 mode.
Powering Off in the L1 Mode
The L1 controller display for each brick should display
L1 running
once the power-off
procedure starts.
Note: If you have a problem while powering off and an error message appears on your
console display, see “L1 Controller Error Messages” on page 164 to learn what the error
message indicates and how to resolve the problem.
To power off your system while in the L1 mode, follow these steps:
1. The prompt on your system shows the rack and slot number of the CR-brick to
which you have connected your console. If you want to power off the CR-brick
(001c05 in our example) indicated in the prompt, enter the following command. (If
you want to power off the bricks connected to the CR-brick, proceed to the next
step.)
001c05-L1> power down
2. If you want to power off the bricks connected to the CR-brick, enter the following
command:
001c05-L1> * power down
