Internal cable routing

Some of the components in the server come with internal cables meant for specific connectors.

Before connecting the cables, read the following guidelines carefully:

• Turn off the server before you connect or disconnect any internal cables.

• Refer to the documentation that comes with any external devices for additional cabling instructions.

• Make use of the identifiers printed on the cables to locate the proper connectors.

• Ensure that the cable is not pinched and does not cover any connectors or obstruct any components on

the system board.

To set up the server, install any options that have been purchased, cable the server, configure and update

the firmware, and install the operating system.

Server setup checklist

Use the server setup checklist to ensure that you have performed all tasks that are required to set up your

server.

The server setup procedure varies depending on the configuration of the server when it was delivered. In

some cases, the server is fully configured and you just need to connect the server to the network and an ac

power source, and then you can power on the server. In other cases, the server needs to have hardware

options installed, requires hardware and firmware configuration, and requires an operating system to be

installed.

The following steps describe the general procedure for setting up a server:

1. Unpack the server package. See “Server package contents” on page 2.

2. Set up the server hardware.

a. Install any required hardware or server options. See the related topics in “Install server hardware

options” on page 33.

b. If necessary, install the server into a standard rack cabinet by using the tower-to-rack conversion kit.

See the documentation that comes with the optional conversion kit.

c. Connect the Ethernet cables and power cords to the server. See “Rear view” on page 10 to locate

the connectors. See “Cable the server” on page 57 for cabling best practices.

d. Power on the server. See “Power on the server” on page 57.

Installation Guidelines

Use the installation guidelines to install components in your server.

Before installing optional devices, read the following notices carefully:

Attention: Prevent exposure to static electricity, which might lead to system halt and loss of data, by

keeping static-sensitive components in their static-protective packages until installation, and handling these

devices with an electrostatic-discharge wrist strap or other grounding system.

• Read the safety information and guidelines to ensure that you work safely.

– A complete list of safety information for all products is available at: http://thinksystem.lenovofiles.com/

help/topic/safety_documentation/pdf_files.html

– “Handling static-sensitive devices” on page 33

• Make sure the components you are installing are supported by the server. For a list of supported optional

components for the server, see https://static.lenovo.com/us/en/serverproven/index.shtml.

• When you install a new server, download and apply the latest firmware. This will help ensure that any

known issues are addressed, and that your server is ready to work with optimal performance. Go to

ThinkSystem ST50 Drivers and Software to download firmware updates for your server.

Important: Some cluster solutions require specific code levels or coordinated code updates. If the

component is part of a cluster solution, verify that the latest level of code is supported for the cluster

solution before you update the code.

• It is good practice to make sure that the server is working correctly before you install an optional

component.

• Keep the working area clean, and place removed components on a flat and smooth surface that does not

shake or tilt.

• Do not attempt to lift an object that might be too heavy for you. If you have to lift a heavy object, read the

following precautions carefully:

– Make sure that you can stand steadily 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.

• Make sure that you have an adequate number of properly grounded electrical outlets for the server,

monitor, and other devices.

• Back up all important data before you make changes related to the disk drives.

• Have a small flat-blade screwdriver, a small Phillips screwdriver, and a T8 torx screwdriver available.

• You do not have to turn off the server to remove or install hot-swap power supplies or hot-plug USB

devices. However, you must turn off the server before you perform any steps that involve removing or

installing adapter cables, and you must disconnect the power source from the server before you perform

any steps that involve removing or installing a DIMM.

• Blue on a component indicates touch points, where you can grip to remove a component from or install it

in the server, open or close a latch, and so on.

• Orange on a component or an orange label on or near a component indicates that the component can be

hot-swapped if the server and operating system support hot-swap capability, which means that you can

remove or install the component while the server is still 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.

• The Red strip on the drives, adjacent to the release latch, indicates that the drive can be hot-swapped if

the server and operating system support hot-swap capability. This means that you can remove or install

the drive while the server is still running.

Note: See the system specific instructions for removing or installing a hot-swap drive for any additional

procedures that you might need to perform before you remove or install the drive.

• After finishing working on the server, make sure you reinstall all safety shields, guards, labels, and ground

wires.

32 ThinkSystem ST50 Setup Guide

System reliability guidelines

The system reliability guidelines to ensure proper system cooling.

Make sure the following requirements are met:

• When the server comes with redundant power, a power supply must be installed in each power-supply

bay.

• Adequate space around the server must be spared to allow 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 any

object in front of the fans.

• For proper cooling and airflow, refit the server cover before you turn the power on. Do not operate the

server for more than 30 minutes with the server cover removed, for it might damage server components.

• Cabling instructions that come with optional components must be followed.

• A failed fan must be replaced within 48 hours since malfunction.

• A removed hot-swap drive must be replaced within two minutes after removal.

• A removed hot-swap power supply must be replaced within two minutes after removal.

• Every air baffle that comes with the server must be installed when the server starts (some servers might

come with more than one air baffle). Operating the server with a missing air baffle might damage the

processor.

• All processor sockets must contain either a socket cover or a processor with heat sink.

• When more than one processor is installed, fan population rules for each server must be strictly followed.

Handling static-sensitive devices

Follow this procedure to handle static-sensitive devices.

Attention: Prevent exposure to static electricity, which might lead to system halt and loss of data, by

keeping static-sensitive components in their static-protective packages until installation, and handling these

devices with an electrostatic-discharge wrist strap or other grounding system.

• Limit your movement to prevent building up static electricity around you.

• Take additional care when handling devices during cold weather, for heating would reduce indoor

humidity and increase static electricity.

• Always use an electrostatic-discharge wrist strap or other grounding system.

• 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 two seconds. This drains static electricity from the package and from your

body.

• Remove the device from the package and install it directly into the server without putting it down. If it is

necessary to put the device down, put it back into the static-protective package. Never place the device

on the server or on any metal surface.

• When handling a device, carefully hold it by the edges or the frame.

• Do not touch solder joints, pins, or exposed circuitry.

• Keep the device from others’ reach to prevent possible damages.

set any passwords.

To start the Setup Utility program, complete the following steps:

Password Types

The following types of passwords are available in the Setup Utility program:

• Power-on password

When a power-on password is set, you are prompted to enter a valid password each time the server is

turned on. The server cannot be used until the valid password is entered.

• Administrator password

Setting an administrator password deters unauthorized users from changing configuration settings. If you

are responsible for maintaining the configuration settings of several servers, you might want to set an

administrator password.

• Hard disk password

Setting a hard disk password prevents unauthorized access to the data on the internal storage drive (such

as a hard disk drive). When a hard disk password is set, you are prompted to enter a valid password each

time you try to access the storage drive.

Notes:

• Even if the storage drive is removed from one server and installed in another, the hard-disk password is

still valid.

• If the hard disk password is forgotten, there is no way to reset the password or recover data from the

storage drive.

Password considerations

A password can be any combination of up to 64 alphabetic and numeric characters. For security reasons, it

is recommended to use a strong password that cannot be easily compromised.

Note: The Setup Utility program passwords are case-sensitive.

62 ThinkSystem ST50 Setup Guide

To set a strong password, consider the following guidelines:

• Have at least eight characters in length

• Contain at least one alphabetic character and one numeric character

• Not be your name or your user name

Memory configuration

Memory performance depends on several variables, such as memory mode, memory speed, memory ranks,

memory population and processor.

More information about optimizing memory performance and configuring memory is available at the Lenovo

Press website:

https://lenovopress.com/servers/options/memory

In addition, you can take advantage of a memory configurator, which is available at the following site:

For specific information about the required installation order of memory modules in your server based on the

system configuration and memory mode that you are implementing, see “DIMM installation rules” on page

38.

RAID configuration

Using a Redundant Array of Independent Disks (RAID) to store data remains one of the most common and

cost-efficient methods to increase server's storage performance, availability, and capacity.

RAID increases performance by allowing multiple drives to process I/O requests simultaneously. RAID can

also prevent data loss in case of a drive failure by reconstructing (or rebuilding) the missing data from the

failed drive using the data from the remaining drives.

RAID array (also known as RAID drive group) is a group of multiple physical drives that uses a certain

common method to distribute data across the drives. A virtual drive (also known as virtual disk or logical

drive) is a partition in the drive group that is made up of contiguous data segments on the drives. Virtual drive

is presented up to the host operating system as a physical disk that can be partitioned to create OS logical

drives or volumes.

An introduction to RAID is available at the following Lenovo Press website:

https://lenovopress.com/lp0578-lenovo-raid-introduction

Detailed information about RAID management tools and resources is available at the following Lenovo Press

website:

https://lenovopress.com/lp0579-lenovo-raid-management-tools-and-resources
