Guidelines for trained service technicians
This section contains information for trained service technicians.
Inspecting for unsafe conditions
Use this information to help you identify potential unsafe conditions in a device
that you are working on.
Each device, as it was designed and manufactured, has required safety items to
protect users and service technicians from injury. The information in this section
addresses only those items. Use good judgment to identify potential unsafe
conditions that might be caused by unsupported alterations or attachment of
unsupported features or optional devices that are not addressed in this section. If
you identify an unsafe condition, you must determine how serious the hazard is
and whether you must correct the problem before you work on the product.
vi Lenovo NeXtScale n1200 Enclosure: Installation and Service Guide

Consider the following conditions and the safety hazards that they present:
vElectrical hazards, especially primary power. Primary voltage on the frame can
cause serious or fatal electrical shock.
vExplosive hazards, such as a damaged CRT face or a bulging capacitor.
vMechanical hazards, such as loose or missing hardware.
To inspect the product for potential unsafe conditions, complete the following
steps:
1. Make sure that the power is off and the power cords are disconnected.
2. Make sure that the exterior cover is not damaged, loose, or broken, and observe
any sharp edges.
3. Check the power cords:
vMake sure that the third-wire ground connector is in good condition. Use a
meter to measure third-wire ground continuity for 0.1 ohm or less between
the external ground pin and the frame ground.
vMake sure that the power cords are the correct type.
vMake sure that the insulation is not frayed or worn.
4. Remove the cover.
5. Check for any obvious unsupported alterations. Use good judgment as to the
safety of any unsupported alterations.
6. Check inside the system for any obvious unsafe conditions, such as metal
filings, contamination, water or other liquid, or signs of fire or smoke damage.
7. Check for worn, frayed, or pinched cables.
8. Make sure that the power-supply cover fasteners (screws or rivets) have not
been removed or tampered with.
Guidelines for servicing electrical equipment
Observe these guidelines when you service electrical equipment.
vCheck the area for electrical hazards such as moist floors, nongrounded power
extension cords, and missing safety grounds.
vUse only approved tools and test equipment. Some hand tools have handles that
are covered with a soft material that does not provide insulation from live
electrical current.
vRegularly inspect and maintain your electrical hand tools for safe operational
condition. Do not use worn or broken tools or testers.
vDo not touch the reflective surface of a dental mirror to a live electrical circuit.
The surface is conductive and can cause personal injury or equipment damage if
it touches a live electrical circuit.
vSome rubber floor mats contain small conductive fibers to decrease electrostatic
discharge. Do not use this type of mat to protect yourself from electrical shock.
vDo not work alone under hazardous conditions or near equipment that has
hazardous voltages.
vLocate the emergency power-off (EPO) switch, disconnecting switch, or electrical
outlet so that you can turn off the power quickly in the event of an electrical
accident.
vDisconnect all power before you perform a mechanical inspection, work near
power supplies, or remove or install main units.
vBefore you work on the equipment, disconnect the power cord. If you cannot
disconnect the power cord, have the customer power-off the wall box that
supplies power to the equipment and lock the wall box in the off position.
Safety vii

vNever assume that power has been disconnected from a circuit. Check it to
make sure that it has been disconnected.
vIf you have to work on equipment that has exposed electrical circuits, observe
the following precautions:
– Make sure that another person who is familiar with the power-off controls is
near you and is available to turn off the power if necessary.
– When you work with powered-on electrical equipment, use only one hand.
Keep the other hand in your pocket or behind your back to avoid creating a
complete circuit that could cause an electrical shock.
– When you use a tester, set the controls correctly and use the approved probe
leads and accessories for that tester.
– Stand on a suitable rubber mat to insulate you from grounds such as metal
floor strips and equipment frames.
vUse extreme care when you measure high voltages.
vTo ensure proper grounding of components such as power supplies, pumps,
blowers, fans, and motor generators, do not service these components outside of
their normal operating locations.
vIf an electrical accident occurs, use caution, turn off the power, and send another
person to get medical aid.
Safety statements
These statements provide the caution and danger information that is used in this
documentation.
Important:

Chapter 1. The NeXtScale n1200 Enclosure Types 5456
The NeXtScale n1200 Enclosure Types 5456 chassis is a 6U next-generation server
platform with integrated fan power control. It is a compact, high-density,
high-performance, rack-mounted, scalable server platform system.
The NeXtScale n1200 Enclosure Types 5456 chassis has twelve node bays. A 1-bay
compute node occupies one node bay in the chassis. A 2-bay storage tray or GPU
tray occupies two node bays in the chassis. The nodes share common resources,
such as power and cooling in the chassis.
The NeXtScale n1200 Enclosure can support the following components:
vUp to twelve 1-bay compute nodes.
vUp to six power supplies.
vTen fan modules.
vOne fan power control.
The chassis system provides the following features:
vCompute node expansion capabilities
You can install up to twelve 1-bay compute nodes in the chassis. Some compute
nodes have connectors for additional optional devices that you can use to add
capabilities to the compute nodes.
vHigh-availability design
The following components in the chassis enable continued operation if one of
the components fails:
–Power supplies
The power supplies support a single power domain that provides power to
all of the chassis components. If a power supply fails, the other power
supplies can continue to provide power. The PSU Redundancy mode that you
have applied for the chassis determines the result of a power-supply failure.
–Fan modules
The fan modules provide cooling to all of the chassis components and the
power supplies have their own fans to provide the cooling.
–Fan power control
The fan power control enables the Integrated Management Module to monitor
the fans and control fan speed.
vChassis midplane
The chassis midplane provides the following features:
– Power distribution to all nodes and modules
The midplane provides hot-swap connectors for the following components:
– Twelve 1-bay compute nodes
– Six power supplies
– Ten fan modules
– Fan power control
