System Reliability Guidelines; Handling Static-Sensitive Devices - IBM LS42 - BladeCenter - 7902 Installation And User Manual

System reliability guidelines

To help ensure proper cooling and system reliability, make sure that the following
requirements are met:
v Each microprocessor socket always contains either a microprocessor dust cover
v Do not operate the BladeCenter unit without a blade server, expansion unit, or
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,

Handling static-sensitive devices

Attention:
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 Limit your movement. Movement can cause static electricity to build up around
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
v Remove the device from its package and install it directly into the blade server
v Take additional care when you handle devices during cold weather. Heating
