Chapter 2. Installation Guidelines

This section covers the installation guidelines that need to be followed when installing components in your
ThinkAgile CP solution.

Before installing optional devices, read the following notices carefully:

Attention:

Exposure to static electricity may lead to system halt and loss of data. Prevent this problem 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:

Safety Information

– The following guidelines are available as well: Handling static-sensitive devices and Working inside the

solution with the power on.

• Make sure the components that you are installing are supported by the solution.

• When you install a new solution, apply the latest firmware. This will ensure that any known issues are

addressed, and that your solution is ready to work with optimal performance. Contact Lenovo Support for
firmware updates.

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 solution 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 may 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.

• 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.

• To view the error LEDs on the system board and internal components, leave the power on.

• You do not have to turn off the solution to remove or install hot-swap power supplies, hot-swap fans, or

hot-plug USB devices. However, you must turn off the solution before you perform any steps that involve
removing or installing adapter cables, and you must disconnect the power source from the solution before
you perform any steps that involve removing or installing a riser card.

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

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

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

the solution and operating system support hot-swap capability. This means that you can remove or install
the drive while the solution is still running.
