Graceful shutdown: Press and release the recessed Power button on the upper left-hand side of 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 main power is off, the LED is not lit.
Caution - When you use the Power button to enter standby power mode, power is still directed to the service processor board 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.
The following illustration shows the recessed Power button on the upper left-hand side of the system front panel.
For instructions on removing the CPU module, refer to the Sun Server X2-8 (formerly Sun Fire X4800 M2) Service Manual.
For the LED locations and descriptions of their behavior, see Troubleshooting DIMM Problems.
For a list of supported PCI cards and DIMMs, refer to the Sun Server X2-8 (formerly Sun Fire X4800 M2) Service Manual.
When main power is applied to the full server, the Power/OK LED next to the Power button blinks intermittently untill BIOS POST finishes.
Refer to the Sun Server X2-8 (formerly Sun Fire X4800 M2) Service Manual for more information about POST and BIOS event logs.
