System reliability guidelines

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

• To ensure proper cooling, the Lenovo 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 microprocessor and heat sink.
• The air baffles are installed over the DIMM connectors.
• The ventilation holes on the compute node are not blocked.
• The compute node CMOS battery is operational. If the CMOS battery becomes defective, replace it immediately.
