Managing the Locate Button/LED

This section provides procedures for turning the Locate Button/LED indicator on and off
remotely (using Oracle ILOM) and locally (using the server Locate Button/LED indicators).
The FIM and back panel Locate Button/LED indicators help you identify the server in a rack
and system.

Description
■ From Main power mode, either press the front panel On/Standby button, or use Oracle ILOM.
When you connect power to the server, the SP boots. The SP OK indicator blinks while the SP is
booting, then remains steady on once it has booted. The System OK indicator flashes briefly every 3
seconds.
A graceful shutdown (also referred to as an orderly shutdown) closes files and prepares the file
system before it shuts down the server to Standby power mode. Graceful Shutdown is the safest
method of shutting down the server.
Power off the server gracefully to prevent data from being corrupted. Performing a graceful shutdown
ensures that the system is ready for restart.
To perform a graceful shutdown use the server OS, Oracle ILOM, or the server front panel Power
button.
An immediate shutdown (also referred to as an emergency shutdown) shuts down the host
immediately without closing files or preparing the file system. Immediate Shutdown should be used
only in situations when you know that the chance of losing data is nonexistent or acceptable.
To completely remove power from the server, remove the power cords.
Shutting down the server from Main power mode to Standby power mode does not completely
remove power from the server. When the server is in Standby power mode, it is in a low-power state.
The low-power state maintains the service processor (SP), which runs Oracle ILOM.
A warm reset is a reboot or restart of the server. It requires cycling the server power from Main power
mode to Standby power mode and back to Main power mode. For example, a warm reset might be
required after a software or firmware update or to access the BIOS Setup Utility.
A cold reset of the server is a restart of the server from a completely powered-off state. A cold reset
might be required to resolve a system issue. To perform a cold reset, place the server in Standby
power mode, disconnect the server from its power source by performing a complete power removal
(see above), wait 30-60 seconds, and then connect the server to its power source.
