DGS-3100 Series Gigabit Stackable Managed Switch Hardware Installation Guide
•
After a device is inserted into the rack, carefully extend the rail into a locking position, and then slide the device
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 or national codes, standards and practices.
CAUTION:
Never override 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 ACL
Profile List Page ground wiring must be inspected by a qualified electrical inspector. An energy hazard
exists if the safety ground cable is omitted or disconnected.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate device components. To prevent static damage, discharge static electricity before touching
any of the electronic components, such as the microprocessor.
To discharge static electricity:
•
Make contact by touching an unpainted metal surface on the chassis.
•
Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads, and
an antistatic grounding strap.
•
Do not remove the component from the antistatic packing material until you are ready to install the system
component. Just before unwrapping the antistatic packaging, discharge static electricity from your body.
•
Place all sensitive components in antistatic containers or packaging when transporting.
Battery Handling Reminder
CAUTION:
The battery can explode if incorrectly replaced. Only replace batteries with the same or
equivalent type recommended by the manufacturer. Discard used batteries in accordance with the
manufacturer's instructions.
