Internally Inspecting the Server

To perform a visual inspection of the internal system:

1.Choose a method for shutting down the server from main power mode to standby power mode. See FIGURE 1-1and FIGURE 1-2.

■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 – Use a ballpoint pen or other stylus to press and hold the Power button for four seconds to force main power off and enter standby power mode.

Caution – Performing an emergency shutdown can cause open files to become corrupt. Use an emergency shutdown only when necessary.

When 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 – When you use the Power button to enter standby power mode, power is still directed to service processor and power supply fans, indicated when the Power/OK LED is flashing. To completely power off the server, you must disconnect the AC power cords from the back panel of the server.
