System reliability guidelines

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

BladeCenter chassis

Each of the module bays on the front and rear of the BladeCenter chassis has either a module or a module bay filler installed in it.
Each of the blade bays on the front of the BladeCenter chassis has either a blade server or a blade bay filler installed in it.
Each of the BladeCenter S system storage module bays has a storage module or storage module filler installed in it. If a storage module is installed, each of the drive bays has a hard disk drive or a hard disk drive bay filler installed in it.
Each of the drive bays in a blade server storage expansion option has either a hot-swap drive or a filler panel installed.
You have followed the cabling instructions that come with optional adapters.
Cables for the optional modules are routed correctly.
A failed fan module is replaced as soon as possible.

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. Operating the server for extended periods of time (more than 30 minutes) with the server cover removed might damage server components.
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 baffles installed. Operating the server without the air baffles might cause the microprocessors to overheat.
Microprocessor 2 air baffle and DIMM air baffle are installed.
The light path diagnostics panel is not pulled out of the server.
