DGS-1510 Series Gigabit Ethernet SmartPro Switch Hardware Installation Guide
• Do not modify power cables or plugs. Consult a licensed electrician or your power company for
site modifications. Always follow your local/national wiring rules.
• When connecting or disconnecting power to hot-pluggable power supplies, if offered with your
system, observe the following guidelines:
o Install the power supply before connecting the power cable to the power supply.
o Unplug the power cable before removing the power supply.
o If the system has multiple sources of power, disconnect power from the system by
• Move products with care; ensure that all casters and/or stabilizers are firmly connected to the
system. Avoid sudden stops and uneven surfaces.
General Precautions for Rack-Mountable Products
Observe the following precautions for rack stability and safety. Also, refer to the rack installation
documentation accompanying the system and the rack for specific caution statements and procedures.
• Systems are considered to be components in a rack. Thus, "component" refers to any system
as well as to various peripherals or supporting hardware.
• 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.
unplugging all power cables from the power supplies.
CAUTION: Installing systems in a rack without the front and side stabilizers installed
could cause the rack to tip over, potentially resulting in bodily injury under
certain circumstances. Therefore, always install the stabilizers before
installing components in the rack. After installing system/components in a
rack, never pull more than one component out of the rack on its slide
assemblies at one time. The weight of more than one extended component
could cause the rack to tip over and may result in serious injury.
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.
