xStack DGS-3400 Series Fast Ethernet Switch
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 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 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.
Completed power and safety ground wiring must be inspected by a qualified electrical
inspector. An energy hazard will exist if the safety ground cable is omitted or
disconnected.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside the system. To prevent static damage, discharge static electricity
from your body before touching any of the electronic components, such as the microprocessor. This can be done by
periodically touching an unpainted metal surface on the chassis.
The following steps can also be taken 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 ready to install the component in the system. Just before unwrapping the antistatic
packaging, be sure to discharge static electricity from your body.
2. When transporting a sensitive component, first place it in an antistatic container or packaging.
3. Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads, workbench pads and an
antistatic grounding strap.
