DGS-3100 Series Gigabit Stackable Managed Switch User Manual
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 your system. To prevent static damage, discharge 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.
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 and workbench pads and
an antistatic grounding strap.
Battery Handling Reminder
CAUTION: This is danger of explosion if the battery is incorrectly replaced. Replace only with the
same or equivalent type recommended by the manufacturer. Discard used batteries according to
the manufacturer's instructions.
