System reliability guidelines
To help ensure proper system cooling and system reliability, make sure the
following requirements are met.
v
Each of the module bays on the front and rear of the BladeCenter S chassis has
either a module or a module bay filler installed in it.
v
Each of the blade bays on the front of the BladeCenter S chassis has either a
blade server or a blade bay filler installed in it.
v
Each of the 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.
v
Each of the drive bays in a blade server storage expansion option has either a
hot-swap drive or a filler panel installed.
v
You have followed the cabling instructions that come with optional adapters.
v
Cables for the optional modules are routed correctly.
v
A failed fan module is replaced as soon as possible.
Handling static-sensitive devices
Make sure that you read these guidelines before handing static-sensitive devices.
Attention: Static electricity can damage the BladeCenter S chassis and other
electronic devices. To avoid damage, keep static-sensitive devices in their
static-protective packages until you are ready to install them.
To reduce the possibility of electrostatic discharge, observe the following
precautions:
v
Limit your movement. Movement can cause static electricity to build up around
you.
v
The use of a grounding system is recommended. For example, wear an
electrostatic-discharge wrist strap, if one is available.
v Handle the device carefully, holding it by its edges or its frame.
v
Do not touch solder joints, pins, or exposed circuitry.
v Do not leave the device where others can handle and damage it.
v
While the device is still in its static-protective package, touch it to an unpainted
metal part of the BladeCenter S chassis or rack for at least 2 seconds. This drains
static electricity from the package and from your body.
v
Remove the device from its package and install it immediately without setting
down the device. If it is necessary to set down the device, put it back into its
static-protective package.
v
Take additional care when you handle devices during cold weather. Heating
reduces indoor humidity and increases static electricity.
