v Ethernet activity LEDs: When these LEDs are lit, they indicate that the server istransmitting to or receiving signals from the Ethernet LAN that is connected tothe Ethernet port.v Ethernet link LEDs: When these LEDs are lit, they indicate that there is anactive link connection on the 10BASE-T, 100BASE-TX, or 1000BASE-TX interfacefor the Ethernet port.v Ethernet connectors: Use either of these connectors to connect the server to anetwork. When you use the Ethernet 1 connector, the network can be sharedwith the IMM through a single network cable.Server power featuresWhen the server is connected to an ac power source but is not turned on, theoperating system does not run, and all core logic except for the service processor(the Integrated Management Module) is shut down; however, the server canrespond to requests to the service processor, such as a remote request to turn onthe server. The power-on LED flashes to indicate that the server is connected to acpower but is not turned on.Turning on the serverApproximately 5 seconds after the server is connected to ac power, one or morefans might start running to provide cooling while the server is connected to powerand the power-on button LED will blink quickly. Approximately 1 to 3 minutesafter the server is connected to ac power, the power-control button becomes active(the power-on LED will blink slowly), and one or more fans might start running toprovide cooling while the server is connected to power. You can turn on the serverby pressing the power-control button.The server can also be turned on in any of the following ways:v If a power failure occurs while the server is turned on, the server will restartautomatically when power is restored.v If your operating system supports the Wake on LAN feature, the Wake on LANfeature can turn on the server.Note: When 4 GB or more of memory (physical or logical) is installed, somememory is reserved for various system resources and is unavailable to theoperating system. The amount of memory that is reserved for system resourcesdepends on the operating system, the configuration of the server, and theconfigured PCI options.Chapter 1.
