• Make sure the components you are installing are supported by the server. For a list of supported optional
components for the server, see http://static.lenovo.com/us/en/serverproven/index.shtml.
• When you install a new server, download and apply the latest firmware. This will help ensure that any
known issues are addressed, and that your server is ready to work with optimal performance. To
download firmware updates for your server, go to D ive s and Softwa e. Add link when site is live
2User Guide forThinkAgile MX Certified Node 2U

Impo tant: 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.
• range 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. ( range 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 eliability 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.
• Adequate space around the server must be spared to allow 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 any
object in front of the fans.
Chapter 1.Lenovo ThinkAgile MX Certified Nodes overview 3

• For proper cooling and airflow, refit the server cover before you turn the power on. Do not operate the
server for more than 30 minutes with the server cover removed, for it might damage server components.
• Cabling instructions that come with optional components must be followed.
• A failed fan must be replaced within 48 hours since malfunction.
• A removed hot-swap fan must be replaced within 30 seconds after removal.
• A removed hot-swap drive must be replaced within two minutes after removal.
• A removed hot-swap power supply must be replaced within two minutes after removal.
• Every air baffle that comes with the server must be installed when the server starts (some servers might
come with more than one air baffle). perating the server with a missing air baffle might damage the
processor.
• All processor sockets must contain either a socket cover or a processor with heat sink.
• When more than one processor is installed, fan population rules for each server must be strictly followed.
Wo king inside the se ve with the powe on
You might need to keep the power on with the server cover removed to look at system information on the
display panel or to replace hot-swap components. Review these guidelines before doing so.
Attention: The server might stop responding and data loss might occur when internal server components
are exposed to static electricity. To avoid this potential problem, always use an electrostatic-discharge wrist
strap or other grounding systems when working inside the server with the power on.
• Avoid loose-fitting clothing, particularly around your forearms. Button or roll up long sleeves before
working inside the server.
• Prevent your necktie, scarf, badge rope, or long hair from dangling into the server.
• Remove jewelry, such as bracelets, necklaces, rings, cuff links, and wrist watches.
• Remove items from your shirt pocket, such as pens and pencils, in case they fall into the server as you
lean over it.
• Avoid dropping any metallic objects, such as paper clips, hairpins, and screws, into the server.
Handling static-sensitive devices
Review these guidelines before you handle static-sensitive devices to reduce the possibility of damage from
electrostatic discharge.
Attention: Prevent exposure to static electricity, which might lead to system halt and loss of data, 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.
• Limit your movement to prevent building up static electricity around you.
• Take additional care when handling devices during cold weather, for heating would reduce indoor
humidity and increase static electricity.
• Always use an electrostatic-discharge wrist strap or other grounding system, particularly when working
inside the server with the power on.
• While the device is still in its static-protective package, touch it to an unpainted metal surface on the
outside of the server for at least two seconds. This drains static electricity from the package and from your
body.
• Remove the device from the package and install it directly into the server without putting it down. If it is
necessary to put the device down, put it back into the static-protective package. Never place the device
on the server or on any metal surface.
4User Guide forThinkAgile MX Certified Node 2U

• When handling a device, carefully hold it by the edges or the frame.
• Do not touch solder joints, pins, or exposed circuitry.
• Keep the device from others’ reach to prevent possible damages.
Chapter 1.Lenovo ThinkAgile MX Certified Nodes overview 5

If your server is installed in a rack, you can use the rack latches to help you slide the server out of the rack.
You also can use the rack latches and screws to secure the server in the rack so that the server cannot slide
out, especially in vibration-prone areas. For more information, refer to the Rack Installation Guide that comes
with your rail kit.
4 D ive bays
The number of the installed drives in your server varies by model. When you install drives, follow the order of
the drive bay numbers.
The EMI integrity and cooling of the server are protected by having all drive bays occupied. The vacant drive
bays must be occupied by drive bay fillers or drive fillers.
