Invoking the SRM Console

or passes control to an operating system. If the system is already running, you can
invoke the SRM Console by:

Pressing the
Reset
button
Both of these actions return you to the SRM Console prompt, >>>.
For example, in a running system, in which control has passed to the Linux
operating system, do one of the following steps to invoke SRM Console mode:
!
Shut down the operating system according to the procedure described in your
operating system documentation. The SRM Console prompt,

Or:
1. Press the
Reset
button. The SRM Console prompt, >>>, appears. You
may now perform tasks in SRM Console mode.
2. At the >>> prompt, type
