Handling static-sensitive devices
Attention: Static electricity can damage electronic devices and your system. To
avoid damage, keep static-sensitive devices in their static-protective packages until
you are ready to install them.
Use an ESD wrist strap and the ESD connectors on the BladeCenter T unit.
Electrostatic discharge (ESD) is the release of stored static electricity that can
damage electric circuits. Static electricity is often stored in your body and
discharged when you come in contact with an object with a different potential. The
ESD wrist strap safely channels the electricity from your body to a proper ground
(the BladeCenter T unit).
Use an ESD wrist strap whenever you are working on the BladeCenter T unit,
especially when you are handling modules, options, and blade servers. To work
properly, the wrist strap must have a good contact at both ends (touching your skin
at one end and connected to the ESD connector on the front or back of the
BladeCenter T unit.)
