Perform these steps to complete POST and Operating System software initialization:
Note This procedure is written assuming that you have connected the CLI console to the controller as
described in “Connecting and Using the CLI Console.”
Step 1 Plug an AC power cord into the rear of the controller, and connect the other end to a grounded 100 to
240 VAC 50/60 Hz electrical outlet.
Note Cisco supplies country specific standard power cord if you order it with the controller; be sure the
controller end of the cord conforms with the IEC 320 standard.
Note If you wish to run a previous version of the controller code, press the <ESC> key immediately after the
Model and S/N line. This will take you to the Bootloader Boot Options Menu.
Step 2 Monitor the controller bootup using the CLI screen:
The Bootup script displays Operating System software initialization (code download and POST
verification) and basic configuration as shown in the following sample bootup display:
.o88b. d888888b .d8888. .o88b. .d88b.
