Working inside the server with the power on
Guidelines to work inside the server with the power on.
Attention:
v
IBM System x3650 M4 BD Type 5466 does not support service on rack.
v
Static electricity that is released to internal server components when the server is
powered-on might cause the server to halt, which might result in the loss of
data. To avoid this potential problem, always use an electrostatic-discharge wrist
strap or other grounding system when you work inside the server with the
power on.
You might have to have the server turned on while the cover is off, to look at light
path diagnostics LEDs or replace hot swap components. Follow these guidelines
when you work inside a server that is turned on:
v
Avoid wearing loose-fitting clothing on your forearms. Button long-sleeved
shirts before working inside the server; do not wear cuff links while you are
working inside the server.
v
Do not allow your necktie or scarf to hang inside the server.
v
Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist
watches.
v
Remove items from your shirt pocket, such as pens and pencils, that could fall
into the server as you lean over it.
v
Avoid dropping any metallic objects, such as paper clips, hairpins, and screws,
into the server.
Handling static-sensitive devices
Use this information to handle static-sensitive devices.
Attention: Static electricity can damage the server and other electronic devices. To
avoid damage, keep static-sensitive devices in their static-protective packages until
you are ready to install them.
To reduce the possibility of damage from electrostatic discharge, observe the
following precautions:
v
Limit your movement. Movement can cause static electricity to build up around
you.
v
The use of a grounding system is highly recommended. For example, wear an
electrostatic-discharge wrist strap, if one is available. Always use an
electrostatic-discharge wrist strap or other grounding system when working
inside the server with the power on
v
Handle the device carefully, holding it by its edges or its frame.
v
Do not touch solder joints, pins, or exposed circuitry.
v
Do not leave the device where others can handle and damage it.
v
While the device is still in its static-protective package, have the device be in
contact 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.
v
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 top
cover or on a metal surface.
v
Take additional care when handling devices during cold weather. Heating
reduces indoor humidity and increases static electricity.
