Protecting Against Electrostatic Discharge - D-Link xStack DES-3800 Series User Manual

•
Before working on the rack, make sure that the stabilizers are secured to the rack, extended to the
floor, and that the full weight of the rack rests on the floor. Install front and side stabilizers on a
single rack or front stabilizers for joined multiple racks before working on the rack.
•
Always load the rack from the bottom up, and load the heaviest item in the rack first.
•
Make sure that the rack is level and stable before extending a component from the rack.
•
Use caution when pressing the component rail release latches and sliding a component into or out
of a rack; the slide rails can pinch your fingers.
•
After a component is inserted into the rack, carefully extend the rail into a locking position, and
then slide the component into the rack.
•
Do not overload the AC supply branch circuit that provides power to the rack. The total rack load
should not exceed 80 percent of the branch circuit rating.
•
Ensure that proper airflow is provided to components in the rack.
•
Do not step on or stand on any component when servicing other components in a rack.
NOTE: A qualified electrician must perform all connections to DC power and
to safety grounds. All electrical wiring must comply with applicable local,
regional or national codes and practices.
CAUTION: Never defeat the ground conductor or operate the equipment in
the absence of a suitably installed ground conductor. Contact the
appropriate electrical inspection authority or an electrician if you are
uncertain that suitable grounding is available.
CAUTION: The system chassis must be positively grounded to the rack
cabinet frame. Do not attempt to connect power to the system until grounding
cables are connected. A qualified electrical inspector must inspect completed
power and safety ground wiring. An energy hazard will exist if the safety
ground cable is omitted or disconnected.
CAUTION: Do not replace the battery with an incorrect type. The risk of
explosion exists if the replacement battery is not the correct lithium battery
type. Dispose of used batteries according to the instructions.

Protecting Against Electrostatic Discharge

Static electricity can harm delicate components inside your system. To prevent static damage, dis-
charge static electricity from your body before you touch any of the electronic components, such as
the microprocessor. You can do so by periodically touching an unpainted metal surface on the chassis.
You can also take the following steps to prevent damage from electrostatic discharge (ESD):
1. When unpacking a static-sensitive component from its shipping carton, do not remove the
component from the antistatic packing material until you are ready to install the component in
your system. Just before unwrapping the antistatic packaging, be sure to discharge static
electricity from your body.
