System reliability guidelines

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

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

• Each of the drive bays has a drive or a filler panel and electromagnetic compatibility (EMC) shield installed in it.
• If the server has redundant power, each of the power-supply bays has a power supply installed in it.
• There is adequate space around the server to allow the server cooling system to work properly. Leave approximately 50 mm (2.0 in.) of open space around the front and rear of the server. Do not place objects in front of the fans. For proper cooling and airflow, replace the server cover before you turn on the server.
• You have followed the cabling instructions that come with optional adapters.
• You have replaced a failed fan within 48 hours.
• You have replaced a hot-swap fan within 30 seconds of removal.
• You have replaced a hot-swap drive within 2 minutes of removal.
• You do not operate the server without the air baffle installed. Operating the server without the air baffle might cause the microprocessor to overheat.
• Microprocessor socket 2 always contains either a microprocessor baffle or a microprocessor and heat sink.
• You have installed the sixth fan when you installed the second microprocessor option.
