Anti-Static Measures

The server contains electronic components sensitive to static electricity. Avoid failures caused by static
electricity when installing or removing any optional devices.
Wear a wrist strap (an arm belt or anti-static glove)
Wear a wrist strap on your wrist. If no wrist strap is available, touch an unpainted metal part of the
chassis before touching a component to discharge static electricity from your body.
Also discharge static electricity by periodically touching a metal surface while working on the
components.
Select a suitable work space
– Work with the server on the anti-static or concrete floor.
– If you work with the server on a carpet where static electricity is likely to be generated, be sure to take
anti-static measures beforehand.
Use a work table
Place the server on an anti-static mat to work with.
Clothing
– Do not wear wool or synthetic clothes.
– Wear anti-static shoes.
– Take off any jewels (a ring, bracelet, or wrist watch) before working with the server.
Handling of components
– Keep any component in an anti-static bag until you actually install it to the server.
– Hold any component by its edge to avoid touching any terminals or parts.
– To store or carry any component, place it in an anti-static bag.
Handling of Cables
When connecting a cable (e.g., LAN cable), static electricity may also be charged due to friction against
the floor. Connecting the charged cable with an I/O device may cause damage to the devices in the
system. It is recommended to use a product such as electrostatic discharge kit to eliminate the static
charge before connecting the cable.
Installing and Removing the Optional Device
– To avoid electric hazard and malfunction, be sure to turn off the power switch of the server and
unplug the power cord from the outlet before installing or uninstalling any optional device. If the
device is hot-swappable, you do not need to turn off the power switch nor unplug the power cord.
– The optional device contains static-sensitive electronic components. When installing or uninstalling
the optional device, wear an anti-static wrist strap on your wrist to avoid a failure caused by the static
electricity. To use the strap, connect the wire to the chassis.
