Lenovo TD100X manual Removing and replacing server components, Installation guidelines

Chapter 4. Removing and replacing server components

Replaceable components are of three types:

vSelf-service customer replaceable unit (CRU): Replacement of self-service CRUs is your responsibility. If Lenovo installs a self-service CRU at your request, you will be charged for the installation.

vOptional-service customer replaceable unit: You may install an optional-service CRU yourself or request Lenovo to install it, at no additional charge, under the type of warranty service that is designated for your server.

vField replaceable unit (FRU): FRUs must be installed only by trained service technicians.

For information about the terms of the warranty and getting service and assistance, see the Warranty and Support Information document.

Installation guidelines

Before you remove or replace a component, read the following information:

vRead the safety information that begins on page vii and the guidelines in “Handling static-sensitive devices” on page 75. This information will help you work safely.

vObserve good housekeeping in the area where you are working. Place removed covers and other parts in a safe place.

vIf you must start the server while the cover is removed, make sure that no one is near the server and that no other objects have been left inside the server.

vDo 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 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

vMake sure that you have an adequate number of properly grounded electrical outlets for the server, monitor, and other devices.

vBack up all important data before you make changes to disk drives.

vHave a small flat-blade screwdriver available.

vYou do not have to turn off the server to install or replace hot-swap power supplies, hot-swap fans, hot-plug adapters, or hot-plug Universal Serial Bus (USB) devices. However, you must turn off the server before performing any steps that involve removing or installing adapter cables.

vBlue 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.

vOrange 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.
