Lenovo BladeCenter HS22, Инструкция по установке и эксплуатации, Страница: 28 / 96

• Blue on a component indicates touch points, where you can grip the component to remove it from or
install it in the blade 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.
• For a list of supported optional devices for the blade server, see

System reliability guidelines
Use this information to make sure that the blade server meets the proper cooling and reliability guidelines.
To help make sure that proper cooling and system reliability requirements are met, review the following
guidelines:
• To ensure proper cooling, do not operate the BladeCenter unit without a blade server, expansion unit,
or blade filler installed in each blade-server bay. See the documentation for your BladeCenter unit for
additional information.
• Each microprocessor socket always contains either a microprocessor dust cover and heat sink filler or
a microprocessor and heat sink. If the blade server has only one microprocessor, it must be installed
in microprocessor socket 1.
• Each DIMM socket always contains a memory module or filler.
• Each hot-swap SAS bay contains a SAS storage drive or filler.
• Make sure that the ventilation holes on the blade server are not blocked.
• The blade server battery must be operational. If the battery becomes defective, replace it immediately.
For instructions, see the Problem Determination and Service Guide .
Handling static-sensitive devices
Use this information to observe the static-sensitive device requirements.
Attention: Static electricity can damage the blade server and other electronic devices. To avoid damage,
keep static-sensitive devices in their static-protective packages until you are ready to install them.
To reduce the possibility of damage from electrostatic discharge, observe the following precautions:
• When you work on a BladeCenter unit that has an electrostatic discharge (ESD) connector, use a wrist
strap, especially when you handle modules, optional devices, or blade servers. To work correctly, the
wrist strap must have a good contact at both ends (touching your skin at one end and firmly connected to
the ESD connector on the front or back of the BladeCenter unit).
• Limit your movement. Movement can cause static electricity to build up around you.
• Handle the device carefully, holding it by its edges or its frame.
• Do not touch solder joints, pins, or exposed circuitry.
• Do not leave the device where others can handle and damage it.
• While the device is still in its static-protective package, touch it to an unpainted metal part of the
BladeCenter unit or any unpainted metal surface on any other grounded rack component in the rack in
which you are installing the device for at least 2 seconds. This drains static electricity from the package
and from your body.
