System reliability guidelines
Use this information to make sure that the blade server meets the proper cooling
and reliability guidelines.
To help make sure that proper cooling and system reliability requirements are met,
review the following guidelines:
v
To ensure proper cooling, do not operate the BladeCenter unit without a blade
server, expansion unit, or blade filler installed in each blade-server bay. See the
documentation for your BladeCenter unit for additional information.
v
Each microprocessor socket always contains either a microprocessor dust cover
and heat sink filler or a microprocessor and heat sink. If the blade server has
only one microprocessor, it must be installed in microprocessor socket 1.
v
DIMMs or DIMM fillers must occupy DIMM connectors 1, 2, 13, 14, 15, and 16
for proper cooling.
v
Each hot-swap SAS bay contains a SAS storage drive or filler.
v
Make sure that the ventilation holes on the blade server are not blocked.
v
The blade server battery must be operational. If the battery becomes defective,
replace it immediately. For instructions, see the Problem Determination and Service
Guide.
Handling static-sensitive devices
Use this information to observe the static-sensitive device requirements.
Attention:
Static electricity can damage the blade server 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 damage from electrostatic discharge, observe the
following precautions:
v
When you work on a BladeCenter unit that has an electrostatic discharge (ESD)
connector, use a wrist strap, especially when you handle modules, optional
devices, or blade servers. To work correctly, the wrist strap must have a good
contact at both ends (touching your skin at one end and firmly connected to the
ESD connector on the front or back of the BladeCenter unit).
v
Limit your movement. Movement can cause static electricity to build up around
you.
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 unit or any unpainted metal surface on any other
grounded rack component in the rack in which you are installing the device 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 directly into the blade server
without setting down the device. If it is necessary to set down the device, put it
back into its static-protective package. Do not place the device on the blade
server cover or on a metal surface.
v
Take additional care when you handle devices during cold weather. Heating
reduces indoor humidity and increases static electricity.
