1.4.2 Powering On Main Power Mode
To power on main power for all server components:
1. Verify that the power cord has been connected and that standby power is on.
In standby power mode, the Power/OK LED on the front panel flashes. See
FIGURE 1-1.
2. Use a non-metallic stylus to press and release the recessed Power button on the
server front panel.
When main power is applied to the full server, the Power/OK LED next to the
Power button lights and remains lit.
1.4.3 Shutting Down Main Power Mode
To power off the server from main power mode, use one of the following two
methods:
■ Graceful shutdown: Use a non-metallic stylus to press and release the Power
button on the front panel. This causes Advanced Configuration and Power
Interface (ACPI) enabled operating systems to perform an orderly shutdown of
the operating system. Servers not running ACPI-enabled operating systems will
shut down to standby power mode immediately.
■ Emergency shutdown: Press and hold the Power button for four seconds to force
the main power off and enter standby power mode. When the main power is off,
the Power/OK LED on the front panel will begin flashing, indicating that the
server is in standby power mode.
Caution – To completely power off the server, you must disconnect the AC power cords
from the back panel of the server.
