System reliability guidelines

Review the system reliability guidelines to ensure proper system cooling and reliability.

Make sure the following requirements are met:

  • When the system comes with redundant power, a power supply must be installed in each power-supply bay.

  • Adequate space around the node and chassis must be spared to allow the cooling system to work properly. Leave approximately 50 mm (2.0 in.) of open space around the front and rear of the chassis. Do not place any object in front of the fans.

  • For proper cooling and airflow, refit the node cover before you turn the power on. Do not operate the node with the node cover removed, for it might damage node components.

  • Cabling instructions that come with optional components must be followed.

  • A removed hot-swap drive must be replaced within two minutes after removal.

  • A removed hot-swap power supply must be replaced by another power supply unit or a PSU filler within two minutes after removal.

  • Every air baffle that comes with the node must be installed when the node starts (some nodes might come with more than one air baffle). Operating the node with a missing air baffle might damage the processor.

  • All processor sockets must contain either a socket cover or a processor with heat sink.
