Removing The Cover; Removing The Air Baffle - Lenovo System x3550 M4 Installation And Service Manual

• Do not touch solder joints, pins, or exposed circuitry.
• Do not leave the device where others can handle and damage it.
• While the device is still in its static-protective package, touch it to an unpainted metal surface on the
outside of the server for at least 2 seconds. This drains static electricity from the package and from
your body.
• Remove the device from its package and install it directly into the 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 server cover or on a metal surface.
• Take additional care when handling devices during cold weather. Heating reduces indoor humidity
and increases static electricity.
