8 Sun Fire X2100 M2 Server Installation Guide • August 2006
▼ To Power On Main Power Mode
To power on main power for all server components:
a. 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 1-3.
b. Use a ballpoint pen or other 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.
Note – The first time the server powers on, the power on self-test (POST) can take
up to a minute.
▼ To Power Off Main Power Mode
To power off the server from main power mode, use one of the following two
methods:
■ Graceful shutdown: Use a ballpoint pen or other 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
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.
