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.
