System reliability guidelines

Use these guidelines to make sure that the Flex System chassis meets cooling and system reliability requirements.

• You do not operate the Flex System chassis without a device or filler installed in each bay. See the documentation for your Flex System chassis for additional information.
• Each of the module bays on the front and rear of the Flex System chassis has either a module or a module filler installed in it.
• Each of the node bays on the front of the Flex System chassis has either a node device or a node filler installed in it.
• Each of the drive bays in a node device has either a hot-swap drive or a panel filler installed in it.
• You replace a removed hot-swap module, node device, or drive within 1 minute of removal. Failure to replace a node device or module with another node device, module, node filler, or module filler within 1 minute can affect performance of the compute nodes.
• Cables for optional modules are routed according to the documents that come with the modules.
• You replace a failed fan module as soon as possible to maintain cooling redundancy. See the documentation for your Flex System chassis for instructions.
