System reliability guidelines

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

• To ensure proper cooling, 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.
• A socket cover and heat-sink filler or a microprocessor and heat sink must always be installed on microprocessor sockets 1, 3, and 4. Microprocessor socket 2 will only have a socket cover when a microprocessor is not install. If the 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 battery is operational. If the CMOS battery becomes defective, replace it immediately.
