System Reliability Guidelines; Handling Static-Sensitive Devices - IBM JS20 - BladeCenter - 8842 Installation And User Manual

System reliability guidelines

To help ensure proper cooling and system reliability, make sure that:
v The ventilation holes on the blade server are not blocked.
v Each of the blade bays on the front of the BladeCenter unit has a blade server or
v You have followed the reliability guidelines in the documentation that comes with
v You have not installed any small computer system interface (SCSI) devices. The

Handling static-sensitive devices

Attention:
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 working on the BladeCenter T unit, use an electrostatic discharge (ESD)
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 printed 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 any unpainted
v Remove the device from its package and install it directly into the blade server or
v Take additional care when handling devices during cold weather. Heating reduces
