Typographic Conventions
Monospace Indicates program code, reserved words, library functions, command-line prompts,
screen output, file/path names, key strokes (e.g., Enter and Alt-Ctrl-F), and
other software constructs.
Monospaced Bold Indicates commands that must be entered on a command line or in response to an
interactive prompt.
Oblique or Italics Indicates user-supplied values in commands or syntax definitions.
Proportional Bold Indicates a graphical user interface window or element.

(lines joined by a backslash are parsed as a single line). Do not type anything after
the backslash or the continuation feature will not work correctly.
Scope and Audience
This publication is intended for Cray service personnel. Personnel must complete XC30-LC and XC40-LC
hardware training before performing these maintenance and replacement procedures.

Torx Fasteners
The XC Series cabinet and blades contain both Torx and Torx+ fasteners. The drivers and bits in the tool kit are
Torx. Torx drivers and bits work with both Torx and Torx+ fasteners.
HSS Component Naming Conventions
This publication refers to the HSS ID of the target component as the hostname. The man pages for the various
commands refer to the target component as the hostname, physIDlist, id-list, or some other name; these
names all refer to the standard HSS ID for the target component. The procedures include an example of the HSS
ID for each command.

1.1 Safety Information
Read and comply with the following safety information while servicing XC30-LC and XC40-LC systems.
DANGER:
● Electrocution Hazard
● Cray requires the power to be disconnected from the PDU when working on components inside the
PDU chassis. If it is necessary to work on components in the PDU with power applied, a minimum 36-
in working clearance must be maintained in front of the PDU. This workspace is required and must be
maintained around all electrical equipment where parts of an energized system may be serviced. To
maintain this clearance, remove the door from the cabinet facing the energized parts, and install an
insulating barrier to prevent any grounded equipment from coming in contact with the energized
components in the PDU. Failure to do so could result in serious injury or death.
WEEE Directive
The Waste Electrical and Electronic Equipment (WEEE) directive of the European Union (EU) is designed to
reduce waste management problems linked to heavy metals and flame retardants. It attempts to limit the amount
of electrical and electronic equipment that enters landfills by encouraging reuse, recycling, and separate
collection. Components that bear the crossed-out wheelie bin symbol require special disposal.
About the XC30-LC and XC40-LC Repair Procedures
7
In accordance with European Directive 2002/96/EC on Waste Electrical and Electronic Equipment (WEEE), the
presence of the crossed-out wheelie bin symbol on a product or on its packaging indicates that you must not
dispose of that item in the normal unsorted municipal waste stream. Instead, it is your responsibility to dispose of
that product by returning it to a collection point that is designated for the recycling of electrical and electronic
equipment waste. Separate collection of this waste helps to optimize the recovery and recycling of any
reclaimable materials and reduces the impact on human health and the environment.
ESD Precautions
Observe electrostatic discharge (ESD) precautions during any maintenance or repair of Cray systems. Required
apparel includes an ESD smock, ESD shoes, and an ESD wrist strap. ESD and Safety Guidelines H-0016,
contains information about safety procedures and potential hazards. Read these guidelines before servicing any
Cray systems.
CAUTION:
● Equipment damage
● Observe all ESD precautions. Failure to do so can result in damage to the equipment.
ESD Smock
Wear a Cray approved static-dissipative smock while servicing or handling an ESD-sensitive device. Completely
button the smock and wear it as the outermost layer of clothing. A portion of the smock’s sleeves must be in direct
contact with the skin of the arms. Skin contact is essential for a dissipative path-to-earth ground. Tuck hair that
exceeds shoulder length inside the back of the smock.
ESD Shoes
Wear approved static-dissipative shoes or approved dissipative heel straps on both shoes while servicing or
handling an ESD-sensitive device. When sensitive equipment is exposed to static discharge, ESD shoes help
prevent an excessive charge from building up.

Blade Handling
Each blade weighs approximately 29 lbs (13 kg). Blades can be removed or installed using a lift.
WARNING:
● Personal injury
● Use and proper lifting techniques when handling blades. Failure to do so could result in serious
personal injury.
CAUTION:
● Equipment damage
● Always observe the ESD and safety precautions described in the previous section when handling
blades. Failure to do so could result in equipment damage.
Safety Measures
Observe the following safety measures to remove, install, repair, or maintain the system.
● Do not wear watches or jewelry while working on a system cabinet.
● Keep fingers and conductive tools away from high-voltage areas and from high-current areas.
DANGER:
● Serious injury or death
● Keep fingers and conductive tools away from high-voltage areas. Serious injury or death will occur if
these precautions are not followed.
WARNING:
● Severe personal injury
● Ensure that the electrical circuit breakers for the equipment being serviced are off, locked, and
tagged. Failure to do so could result in severe shock and burns.
● Remove all tools from the system cabinets after performing service.
● Replace all covers and panels that were removed from the system during servicing.
● Some procedures require powering off the system; power off the system only after shutting down the system
software in an orderly manner.
CAUTION:
● Loss of data
● Do not power off the system before halting the operating system. Failure to do so could result in loss
of data.
Cray systems may reach noise levels where the use of hearing protection is required. The need for this protection
depends on such factors as the number of installed cabinets, the speed of the blowers, and the physical design
and the materials used in the computer room. The use of hearing protection is highly recommended for all

or other country's regulatory levels.
