Approximately 5 minutes, or up to 8 minutes in a 2-node configuration, 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. You can turn on the server and all nodes in the partition and start the operating system by pressing the power-control button.

If you are restarting a two-node server after it has been turned off, you must allow extra time for the hardware to synchronize before you turn on the server again.

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 The systems-management software can turn on the server remotely. v If your operating system supports the Wake on LAN feature, the Wake on LAN

feature can turn on the server.

Note: Some 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 IMM, 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.

Important: To view the error LEDs on the system board, leave the server connected to a 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.

Turning the MAX5 on and off

Because the MAX5 expansion module is controlled by the server, turning on the MAX5 refers to connecting the MAX5 power cord to the power source and pressing the power-control button on the host server that is connected to the MAX5 expansion module and is configured to identify the expansion module. Normally, the operating system on the server starts, and the server issues a power-on request to the MAX5. The IBM MAX5 for System x (MAX5) memory expansion module is turned off only if the connected server issues a power-off request and you disconnect the MAX5 power cord from the power source. You cannot turn off the MAX5 expansion module manually.

Statement 5:

You can disconnect the MAX5 expansion module power cords from the power source to shut off all power immediately without damaging the MAX5, but it might cause an unrecoverable error and loss of data on the connected server.

In a two-node configuration, make sure that the IBM System x Server Firmware, FPGA, and IMM code are at the same levels on all nodes.

v Before you install optional hardware devices, make sure that the server is

v Observe good housekeeping in the area where you are working. Place removed

covers and other parts in a safe place.

v If you must start the server while the cover is removed, make sure that no one is

near the server and that no tools or other objects have been left inside the server.

v Do not attempt to lift an object that you think is too heavy for you. If you have to

lift a heavy object, observe the following precautions: – Make sure that you can stand safely without slipping. – Distribute the weight of the object equally between your feet. – Use a slow lifting force. Never move suddenly or twist when you lift a heavy

object.

– To avoid straining the muscles in your back, lift by standing or by pushing up

with your leg muscles.

v Make sure that you have an adequate number of properly grounded electrical

outlets for the server, monitor, and other devices.

v Back up all important data before you make changes to disk drives. v Have a small flat-blade screwdriver available. v To view the error LEDs on the system board and internal components, leave the

server connected to power.

v You do not have to turn off the server to install or replace hot-swap power

supplies, hot-swap hard disk drives, hot-swap fans, or hot-plug Universal Serial Bus (USB) devices. However, you must turn off the server before you perform any steps that involve removing or installing adapter cables.

v Blue on a component indicates touch points, where you can grip the component

to remove it from or install it in the server, open or close a latch, and so on.

v Orange on a component or an orange label on or near a component indicates

that the component can be hot-swapped, which means that if the server and operating system support hot-swap capability, you can remove or install the component while the server is running. (Orange can also indicate touch points on hot-swap components.) See the instructions for removing or installing a specific hot-swap component for any additional procedures that you might have to perform before you remove or install the component.

v When you are finished working on the server, reinstall all safety shields, guards,

labels, and ground wires.

Chapter 2. Installing optional devices 33

v For a list of supported optional devices for the server, see http://www.ibm.com/

servers/eserver/serverproven/compat/us/.

A single-power-supply server operating at 208 V ac

One power supply operating at 208 V ac supports a fully populated server, but it does not support power or cooling redundancy.

System reliability guidelines

To help ensure proper cooling and system reliability, make sure that the following requirements are met:

v Each of the drive bays has a drive or an electromagnetic compatibility (EMC)

shield installed in it.

v If the server has redundant power, each of the power-supply bays has a power

supply installed in it.

v There is adequate space around the server to allow the server cooling system to

work properly. Leave approximately 50 mm (2.0 in.) of open space around the front and rear of the server. Do not place objects in front of the fans. For proper cooling and airflow, replace the top cover before you turn on the server. Operating the server for extended periods of time (more than 30 minutes) with the top cover removed might damage server components.

v You have followed the cabling instructions that come with optional adapters. v You have replaced a failed fan within 48 hours. v You have replaced a hot-swap drive within 2 minutes of removal. v For redundant and hot-swappable power supply operation, the power supplies

are connected to 200-240 V ac.

v Microprocessor sockets1-4each always contain either a heat-sink blank or a

microprocessor and heat sink.

Working inside the server with the power on

Attention: Static electricity that is released to internal server components when

the server is powered on might cause the server to halt, which might result in the loss of data. To avoid this potential problem, always use an electrostatic-discharge wrist strap or other grounding system when you work inside the server with the power on.

The server supports hot-swap devices and is designed to operate safely while it is turned on and the cover is removed. Follow these guidelines when you work inside a server that is turned on:

v Avoid wearing loose-fitting clothing on your forearms. Button long-sleeved shirts

before you work inside the server; do not wear cuff links while you are working inside the server.

v Do not allow your necktie or scarf to hang inside the server. v Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist

watches.

v Remove items from your shirt pocket, such as pens and pencils, that might fall

into the server as you lean over it.

v Avoid dropping any metallic objects, such as paper clips, hairpins, and screws,

into the server.

Handling static-sensitive devices

Attention: Static electricity can damage the server and other electronic devices.

To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.

To reduce the possibility of damage from electrostatic discharge, observe the following precautions:

v Limit your movement. Movement can cause static electricity to build up around

you.

v Wear an electrostatic-discharge wrist strap, if one is available. v Handle the device carefully, holding it by its edges or its frame. v Do not touch solder joints, pins, or exposed circuitry. v Do not leave the device where others can handle and damage it. v While the device is still in its static-protective package, touch it to an unpainted

metal surface on the outside of the server for at least 2 seconds. This drains static electricity from the package and from your body.

v Remove the device from its package and install it directly into the server without

setting down the device. If it is necessary to set down the device, put it back into its static-protective package. Do not place the device on the server cover or on a metal surface.

v Take additional care when you handle devices during cold weather. Heating

reduces indoor humidity and increases static electricity.

v The server supports up to eight 1-inch (26 mm) slim-high, 2.5-inch, hot-swap

hard disk drives in the standard hot-swap bays.

v Start installing the hard disk drives from the bottom bay (bay 0). v For a list of supported optional devices for the server, see http://www.ibm.com/

servers/eserver/serverproven/compat/us/.

v If the server will be configured for RAID operation, see the documentation that

comes with the controller for instructions for installing a hard disk drive.

v All hot-swap drives in the server should have the same throughput speed rating;

using drives with different speed ratings might cause all drives to operate at the lowest throughput speed.

v To minimize the possibility of damage to the hard disk drives when you install the

Installing a MAX5 memory module

The following notes describe the types of DIMMs that the MAX5 memory expansion module supports and other information that you must consider when you install DIMMs.

v The MAX5 supports a maximum of 32 DIMMs (single-rank, dual-rank, or

quad-rank).

Note: To determine the type of a DIMM, see the label on the DIMM. The information on the label is in the format xxxxx nRxxx PC3-xxxxx-xx-xx-xxx. The numeral in the sixth numerical position indicates whether the DIMM is single-rank (n=1) or dual-rank (n=2).

v The DIMM options that are available for the MAX5 are 2 GB, 4 GB, 8 GB, and

16 GB (when available).

v The MAX5 supports a minimum of 4 GB and a maximum of 512 GB of system

memory.

v When you populate DIMMs in the MAX5, populate the larger capacity DIMMs

first; then the smaller capacity DIMMs. See Table 10 on page 76 for non-mirroring mode DIMM population sequence and Table 11 on page 77 for memory-mirroring mode DIMM population sequence.

v The MAX5 provides eight memory ports (memory channels) and each memory

port supports up to four DIMMs. Do not mix DIMMs with x4 technology (DIMMs with DRAMs that are organized with 4 data lanes) and x8 technology (DIMMs with DRAMs that are organized with 8 data lanes) in the same memory port.

v DIMMs must be installed in pairs for non-mirroring mode and in sets of four for

memory-mirroring mode.

v A minimum of two DIMMs must be installed in the MAX5 for each microprocessor

in the host server.

v The maximum operating speed of the MAX5 is determined by the slowest DIMM

installed in the MAX5.

v The MAX5 does not come with any DIMMs installed when you purchase it as a

option. When you install DIMMs, install them in the order shown in the following tables to optimize system performance.

v The server supports non-mirroring mode and memory-mirroring mode.

– Non-mirroring mode. When you use the non-mirroring mode, install DIMMs

as indicated in the following table:

Table 10. Non-mirroring mode DIMM population sequence for the MAX5 memory expansion module

Note: When you populate DIMMs in the MAX5, populate the larger capacity DIMMs first; then the smaller capacity DIMMs.

– Memory-mirroring mode. When you use the mirroring mode feature,

consider the following information:

- Memory-mirroring mode replicates and stores data on sets of DIMMs simultaneously. If a failure occurs, the memory controller switches from the primary set of DIMMs to the backup set of DIMMs. To enable memory mirroring through the Setup utility, select System Settings → Memory. For more information, see “Using the Setup utility” on page 87.

76 IBM System x3850 X5 and x3950 X5 Types 7145 and 7146: Installation and User’s Guide

- DIMMs must be installed in sets of four. The DIMMs in each set must be

the same size and type. This is applicable also when the MAX5 expansion module is attached to a host server and the host server has an optional memory tray installed in the server. You must install DIMMs in sets of four DIMMs for memory-mirroring mode in each (server, memory tray, and the MAX5).

- The maximum available memory is reduced to half of the installed memory

when memory mirroring is enabled. For example, if the MAX5 expansion module has 64 GB of memory installed, only 32 GB of addressable memory is available when you use memory mirroring.

- The following table lists the DIMM installation sequence for

memory-mirroring mode.
