• When you install your new server, take the opportunity to download and apply the most recent firmware
updates. This step will help to ensure that any known issues are addressed and that your server is ready
to function at maximum levels of performance. To download firmware updates for your server, go to
Important:
Some cluster solutions require specific code levels or coordinated code updates. If the device
is part of a cluster solution, verify that the latest level of code is supported for the cluster solution before
you update the code.

• Observe good housekeeping in the area where you are working. Place removed parts in a safe place.
• 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.
• 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 to disk drives.
• Have a Phillips screwdriver available for the heatsinks.
• You do not have to turn off the server to install or replace hot-swap power supplies, hot-swap fans, or hot-
plug Universal Serial Bus (USB) devices. However, you must turn off the server before you perform any
steps that involve removing or installing adapter cables.
• Blue 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.
• Orange 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.
• When you are finished working on the server, reinstall all safety shields, guards, labels, and ground wires.
System reliability guidelines
Use this information to understand what you need to do to ensure that the system cooling and system
reliability requirements are met.
To help ensure proper system cooling and system reliability, make sure that the following requirements are
met:
• Each of the drive bays has a drive or a filler panel and electromagnetic compatibility (EMC) shield installed
in it.
• Each of the power-supply bays has a power supply or a filler installed in it.
• There is adequate space around the server to allow the 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 objects
in front of the fans. For proper cooling and airflow, replace the server cover before you turn on the server.
• You have followed the cabling instructions that come with optional adapters.
• You have replaced a hot-swap fan within 30 seconds of removal.
