What your server offers

The server uses the following features and technologies:

v Active PCI-X (hot-plug) adapter capabilities

The server has six hot-plug slots for peripheral component interconnect (PCI-X) adapters. With operating-system support, you can replace a failing hot-plug PCI-X adapter without turning off the server. If the operating system and adapter support the hot-add feature, you can also add a PCI adapter in one of these slots without turning off the server.

v Baseboard management controller

The baseboard management controller provides environmental monitoring for the server. If environmental conditions exceed thresholds or if system components fail, the baseboard management controller lights LEDs to help you diagnose the problem and records the errors in the error log. The baseboard management controller is also known as the service processor.

The baseboard management controller also provides remote server management capabilities through the OSA SMBridge management utility program.

v IBM Director

IBM Director is a workgroup-hardware-management tool that you can use to centrally manage IBM System x and xSeries servers. For more information, see the IBM Director documentation on the IBM Director CD.

v IBM Enterprise X-Architecture technology

IBM X-Architecture technology combines proven, innovative IBM designs to make your x86-based server powerful, scalable, and reliable. For more information, see http://www.ibm.com/servers/eserver/xseries/xarchitecture/enterprise/index.html.

For more information, including the required levels of IBM Director and PowerExecutive, see the IBM Director documentation on the IBM Director CD, or go to http://www.ibm.com/servers/eserver/xseries/systems_management/ibm_director /extensions.

v Redundant connection

The addition of an optional network interface card (NIC) provides a failover capability to a redundant Ethernet connection. If a problem occurs with the primary Ethernet connection, all Ethernet traffic that is associated with the primary connection is automatically switched to the redundant NIC. If the applicable device drivers are installed, this switching occurs without data loss and without user intervention.

v Redundant cooling and power capabilities

The redundant cooling of the fans in the server enable continued operation if one of the fans fails. The server supports up to two hot-swap power supplies, which provide redundant power for many server configurations.

v Scalable partitions

The server is scalable and can be connected to multiple servers so that you can share resources between servers.

v ServeRAID™ support

The server supports ServeRAID adapters to create redundant array of independent disks (RAID) configurations.

v Symmetric multiprocessing (SMP)

The server supports up to four Intel Xeon microprocessors. If the server comes with only one microprocessor, you can install additional microprocessors to enhance performance and provide SMP capability.

v Information LED: When this LED is lit, it indicates that there is a suboptimal

condition in the server and that light path diagnostics will light an additional LED to help isolate the condition. If the LOG LED on the light path diagnostics panel is lit, information is available in the baseboard management controller (BMC) log or in the system-event log about the condition. The condition might be that the BMC log is full or almost full.

Chapter 1. The System x3950 and System x3950 E server 9

This LED and LEDs on the light path diagnostics panel remain lit until you resolve the condition. If the only condition is that the BMC log is full or almost full, clear the BMC log or the system-event log through the Configuration/Setup Utility program to turn off the lit LEDs. See “Using the Configuration/Setup Utility program” on page 58 for information about clearing the logs. Clear the logs after you have resolved all conditions.

Important: If the server has a baseboard management controller, clear the BMC

log and system-event log after you resolve all conditions. This will turn off the information LED and LOG LED, if all conditions are resolved.

v Release latch: Slide this latch to the left to access the light path diagnostics

panel.

v System-error LED: When this LED is lit, it indicates that a system error has

occurred. An LED on the light path diagnostics panel is also lit to help isolate the error.

v Locator LED: When this LED is lit, it has been lit remotely by the system

administrator to aid in visually locating the server.

In multi-node configurations, when this LED flashes during startup, it indicates that the server is the primary node. When this LED is lit during startup, it indicates that the server is a secondary node.

v Hard disk drive activity LED: When this LED is flashing, it indicates that a SAS

hard disk drive is in use.

v Power-on LED: When this LED is lit and not flashing, it indicates that the server

is turned on. When this LED is flashing, it indicates that the server is turned off and still connected to an ac power source. When this LED is off, it indicates that ac power is not present, or the power supply or the LED itself has failed.

Note: If this LED is off, it does not mean that there is no electrical power in the

server. The LED might be burned out. To remove all electrical power from the server, you must disconnect the power cords from the electrical outlets.

Server power features

When the server is connected to an ac power source but is not turned on, the operating system does not run, and all core logic except for the service processor is shut down; however, the server can respond to requests from the service processor, such as a remote request to turn on the server. The power-on LED flashes to indicate that the server is connected to ac power but not turned on.

12 IBM System x3950 Type 8878 and System x3950 E Type 8879: User’s Guide

Turning on the server

Approximately 20 seconds after the server is connected to ac power, the power-control button becomes active, and one or more fans might start running to provide cooling while the server is connected to power. Yo u can turn on the server and start the operating system by pressing the power-control button.

Note: If a Remote Supervisor Adapter II SlimLine is installed in the server, during

initial startup, the server might appear to be unresponsive for an unusual length of time (one minute to several minutes).

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 restart

automatically when power is restored.

v If the server is installed in a static partition, you can turn on the server and start

the operating system by pressing the power-control button on the primary node in the partition.

v If your operating system supports the systems-management software for the

Remote Supervisor Adapter II SlimLine, the systems-management software can turn on the server.

feature can turn on the server.

When 4 GB or more of memory (physical or logical) is installed, some

Note:

memory is reserved for various system resources and is unavailable to the operating system. The amount of memory that is reserved for system resources depends on the operating system, the configuration of the server, and the configured PCI options.

Turning off the server

When you turn off the server and leave it connected to ac power, the server can respond to requests from the service processor, such as a remote request to turn on the server. While the server remains connected to ac power, one or more fans might continue to run. To remove all power from the server, you must disconnect it from the power source.

Some operating systems require an orderly shutdown before you turn off the server. See your operating-system documentation for information about shutting down the operating system.
