System reliability guidelines

To help ensure proper system cooling and system reliability, make sure that the following requirements are met:

• To ensure proper cooling, do not operate the chassis without a compute node or a filler in each node bay.
• You have replaced a compute node within 3 minutes of removal or a filler is installed.
• Make sure that the ventilation holes on the compute node are not blocked.
• The compute node CMOS battery must be operational. If the CMOS battery becomes defective, replace it immediately. See the documentation that comes with the compute node for instructions.
• Replace the fan power control as soon as possible after removal to ensure proper operation of the chassis.
