DGS-3100 Series Gigabit Stackable Managed Switch Hardware Installation Guide
•
115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries such as South
Korea and Taiwan
•
100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan
•
230 V/50 Hz in most of Europe, the Middle East, and the Far East
•
Ensure that the device is electrically rated to operate with the local power supply.
•
Use only approved power cables. If power cables are not provided, purchase a power cable that is approved for use
in the relevant country. The power cable must be rated for the product, the voltage and the power current must be
marked on the product's electrical ratings label. The voltage and current rating of the cable must be greater than the
ratings marked on the product.
To help prevent electric shock:
•
Plug the system and peripheral power cables into properly grounded electrical outlets. These cables are equipped
with three-prong plugs to help ensure proper grounding. Do not use adapter plugs or remove the grounding prong
from a cable. If an extension cable is necessary, use a 3-wire cable with properly grounded plugs.
•
Observe extension cable and power strip ratings. Ensure that the total ampere rating of all products plugged into the
extension cable or power strip does not exceed 80 percent of the ampere ratings limit for the extension cable or
power strip.
To help protect your system from sudden, transient increases and decreases in electrical power, use a surge suppressor, line
conditioner, or
Uninterruptible Power Supply (UPS).
•
Position system cables and power cables carefully; route cables so that they cannot be stepped on or tripped over.
Ensure that nothing rests on any of the cables.
•
Do not modify power cables or plugs. Consult a licensed electrician or the power company for site modifications.
Always follow the local/national wiring standards.
•
When connecting or disconnecting power to hot-pluggable power supplies, if offered with the device, observe the
following guidelines:
– Install the power supply before connecting the power cable to the power supply.
– Unplug the power cable before removing the power supply.
– If the system has multiple sources of power, disconnect power from the system by unplugging all power cables
from the power supplies.
•
Move products with care; ensure that all casters and/or stabilizers are firmly connected to the system.
•
Avoid sudden stops and uneven surfaces.
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.
General Precautions for Rack-Mountable Products
10
CAUTION: Always install the stabilizers before installing components in the rack. 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.
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.
Before working on the rack:
•
Ensure that the stabilizers are secured to the rack and extended to the floor.
•
Ensure that the entire rack weight 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.
•
Ensure that the rack is level and stable before extending a component from the rack.
•
Use caution when pressing the device rail release latches and sliding a device into or out of a rack; the slide rails
can pinch your fingers.
