System reliability guidelines

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

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.
• Each of the power-supply bays has a power supply or a filler 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 have replaced a failed hot-swap power supply within 2 minutes of removal.
• You do not operate the server without the air baffles installed. Operating the server without the air baffles might cause the device to overheat.
