Ethernet connectorUse this connector to connect the server to a network.Ethernet transmit/receive activity LEDThis LED is on the Ethernet connector on the rear of the server. When thisLED is lit, it indicates that there is activity between the server and thenetwork.Ethernet link status LEDThis LED is on the Ethernet connector on the rear of the server. When thisLED is lit, it indicates that there is an active connection on the Ethernetport.Remote Supervisor Adapter II SlimLine Ethernet connectorUse this connector to connect the Remote Supervisor Adapter II SlimLine toa network.AC power LEDOn some server models, each hot-swap power supply has an ac powerLED and a dc power LED. During typical operation, both the ac and dcpower LEDs are lit.DC power LEDOn some server models, each hot-swap power supply has a dc power LEDand an ac power LED. During typical operation, both the ac and dc powerLEDs are lit.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 is shut down; however, the servercan respond to remote requests to turn on the server.Turning on the serverApproximately 20 seconds after the server is connected to ac power, thepower-control button becomes active, and you can turn on the server and start theoperating system by 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 systems-management software for anoptional Remote Supervisor Adapter II SlimLine, the systems-managementsoftware can turn on the server.v If your operating system supports the Wake on LAN feature, the Wake on LANfeature can turn on the server.v If an optional Remote Supervisor Adapter II SlimLine is installed in the server, theserver can be turned on from the Remote Supervisor Adapter II SlimLine userinterface.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 optional devices.Chapter 1. Introduction 7
