Review the system reliability guidelines to ensure proper
system cooling and reliability.
Make sure the following
requirements are met:
- To ensure proper cooling, the Flex System
chassis is not operated without a compute node or node bay filler
in each node bay.
- When the compute node comes with redundant power, a power supply
must be installed in each power-supply bay.
- Adequate space around the compute node must be spared to allow
compute node cooling system to work properly. Leave approximately
50 mm (2.0 in.) of open space around the front and rear of the compute
node. Do not place any object in front of the fans.
- For proper cooling and airflow, refit the compute node cover before
you turn the power on. Do not operate the compute node for more than
30 minutes with the compute node cover removed, for it might damage
compute node components.
- Cabling instructions that come with optional components must be
followed.
- A failed fan must be replaced within 48 hours after malfunction.
- A removed hot-swap fan must be replaced within 30 seconds after
removal.
- A removed hot-swap drive must be replaced within two minutes after
removal.
- A removed hot-swap power supply must be replaced within two minutes
after removal.
- Every air baffle that comes with the compute node must be installed
when the compute node starts (some servers might come with more than
one air baffle). Operating the compute node with a missing air baffle
might damage the processor.
- All processor sockets must contain either a socket cover or a
processor with heat sink.
- When more than one processor is installed, fan population rules
for each compute node must be strictly followed.
