System reliability guidelines

Use these guidelines to ensure that the compute node meets the cooling and system reliability requirements:

  • The Flex System chassis is not operated without a compute node or node bay filler in each node bay. See "Flex System Enterprise Chassis Types 8721, 8724, and 8725: Installation and Service Guide" for additional information.
  • Each microprocessor socket always contains a socket cover and heat-sink filler or a microprocessor and heat sink. If the upper or lower compute node has only one microprocessor, it must be installed in microprocessor socket 1.
  • The air baffles are installed over the DIMM connectors.
  • The ventilation holes on the compute node are not blocked.
  • The compute node CMOS batteries are operational. If a CMOS battery becomes defective, replace it immediately.
