Anti-static Measures

The server contains static-sensitive components. Follow the measures below to avoid a failure caused by
static electricity when installing or uninstalling any optional device.

Wearing Anti-static Wrist Strap or Anti-static Gloves
Wear a wrist strap on your wrist and connect the wire to the chassis. If there is no wrist strap, touch an
unpainted metal surface of the chassis connected to the ground to discharge static electricity from your
body before touching the component. Touch the metal part occasionally to discharge the static electricity
while working on the component.

Checking the Workplace
 Work on an anti-static floor or concrete floor.
 If you work on a place where static electricity is likely to be generated (such as carpet), be sure to
provide anti-static protection.

Using the Work Table
Place the server on a mat with Electrostatic Discharge (ESD) protection.

Clothing
 Do not wear wool or synthetic clothes.
 Wear anti-static shoes.
 Remove a ring, bracelet, wrist watch, and any kind of metal accessories.

Handling of Components
 Keep the component in an anti-static bag until you install it to the server.
 Hold the component by the edges to avoid touching any terminals or mounting parts.
 Place the component in an anti-static bag when storing or moving them.

Handling of Cables
When connecting a cable (a long LAN cable), static electricity may also be charged due to friction against
the floor. Connecting the charged cable to the server will cause damage to the internal devices of the
server. It is recommended to use a product such as electrostatic discharge kit to eliminate the static charge
before connecting the cable.

Installing and Uninstalling 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 a hot-plug device, you do not need to turn off the power switch and unplug the power
cord.
 The 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.
