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

working correctly. If the server is not working correctly, refer to Chapter 3,

“Diagnostics,” on page 13 for your server for detailed diagnostic information. To

obtain the publication, go to:

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

covers and other parts in a safe place.

v If you must turn on the server while the server 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 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 fans,

redundant hot-swap ac power supplies, or hot-plug USB devices. However, you

must turn off the server before performing any steps that involve installing,

removing, or replacing adapter cables or non-hot-swap optional devices or

components.

v After completing any installation, removal, or replacement procedure, reinstall

all safety shields, guards, labels, and ground wires.

v For a list of supported optional devices for the server, go to

http://www.lenovo.com/thinkserver.

v When working inside the server, you might find some tasks easier if you lay the

server on its side.

System reliability guidelines

To help ensure proper cooling and system reliability, make sure that you follow

these guidelines:

v Every drive bay has an internal drive installed or an Electro Magnetic

Compatibility (EMC) shield installed.

v If the server has redundant power, every power supply bay has a power supply

assembly installed.

v Leave adequate space around the server to make sure that the server cooling

system works well.

v Properly route the cables. For some options, such as PCI cards, follow the

cabling instructions that come with the options.

v Make sure that you replace a failing fan within 48 hours.

v When replacing a hot-swap drive, install the new hot-swap drive within two

minutes of removal.
