12.3 Restarting the System
Note – As the system starts up, watch for error messages from the POST
diagnostic program. If a terminal is not already part of the system, install a
TTY terminal before continuing the startup. See Section9.1, “Using a
Terminal,”on page 9-1 for terminal settings.
1. The system key switch must be turned to (the standby position).
See Figure12-1 or Figure 12-3.
Caution – The outlet must be a 120-240 VAC30-ampere circuit, intended solely
for use by the server cabinet, as described in the site preparationinstructions in
the Ultra Enterprise 6000/5000/4000 Systems Installation Guide. The electrical
receptacle must be grounded, and the grounding conductor serving this
receptacle must be connected to the earth ground at the service equipment.

Local.
See Figure 12-6.
