Powering the System On and Off

Powering On at the System Console
The power-on procedure at a system console varies with your server setup, as follows:
• If you have a system console, 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.
• If you have a system console connected to a server with an ethernet interface, you
can toggle between L1 and console mode, and power on your server with L1
controller commands, and monitor the power-on 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 25.
See the section “Console Hardware Requirements” in Chapter 2, and the SGIconsole
Hardware Connectivity Guide , P/N 007-4340-00 x for additional information on the
optional SGI console.
Powering On in the L1 Mode
The following sections describe how to power on your system in L1 mode.
The L1 controller display, located on the front of each brick, should display
L1 running
once the power-on procedure starts.
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 164 to learn what the error
message indicates and how to resolve the problem.
To power on 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 on the CR-brick
(001c05 in our example) indicated in the prompt, enter the following command. (If
you want to power on the bricks connected to the CR-brick, proceed to the next
step.)
