Removing and Installing Processors Note
If the serverhas been running, any installed processor and heat sink on the
processor board(s)will be hot. To avoidthe possibility of a burn, allow the
unit to cool-down and be careful when removingor installing server board
componentsthat are locatednear processors.
Processor must be appropriate: Youmay damage the server if you install
a processorthat is i nappropriatefor your server. Make sure your servercan
handle a newer,faster processor (thermal and power considerations). For
exact informationabout processor interchangeability, contact your customer
servicerepresentative.
Handling Static-sensitive Devices
Attention: Static electricity can damage electronicdevices and your system. To avoid damage,
keep static-sensitivedevices in their static-protective package until you are readyto install them.
To reduce the possibilityof electrostatic discharge, observe the following precautions:
• Limit your movement. Movementcan cause static electricity to build up around you.
• Handle the device carefully,holding it by its edges or its frame.
• Do not touch solder joints, pins, or exposed printed circuitry.
• Do not leave thedevice where others can handle and possibly damage the device.
• While the deviceis stillin its anti-static package, touch it to an unpainted metalpart of the
systemunit forat least two seconds. (Thisdrains static electricity from the package and from
your body.)
• Removethe device from its package and install it directly into your systemunit without setting
it down. Ifit is necessary to set the device down, place it in its static-protective package. Do
not place thedevice on your system unit cover or on a metal table.
• Take additionalcare when handling devices during cold weather because heating reduces
indoor humidityand increasesstatic electricity.
