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.

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

• You do not have to turn off the server to remove or install hot-swap power supplies, hot-swap fans, 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 riser card.

• 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.

System reliability guidelines

Review the system reliability guidelines to ensure proper system cooling and reliability.

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.
